Infinitra ACB1 16 Button Controller - Full Vehicle Lighting Install & Control has Never Been Easier!
A light bar is only as useful as the controls behind it. If the buttons are confusing, hard to reach, or slow to change, the whole system becomes harder to use when it matters most.
The Infinitra ACB1 16 Button programmable controller is built to solve that problem. It gives the Infinitra light bar a dedicated control panel with 16 clearly arranged buttons, direct output control through the central control box, and dedicated system keys for pattern, color, speed, and brightness changes.
Instead of digging through menus or relying on a generic switch panel, the controller puts the most common light bar actions in front of the operator. Turn on a programmed function, cut front-facing modules, change flash speed, adjust intensity, or move through light patterns with simple button presses.
And all of this is running on the new PLC2.0 platform... our newest generation of Power-Link technology that works as fast as you as you press the button, installs easily with our power bus system that sends control commands over the power lines, and customizable for any vehicle. Easily run your own lights with our PLC2.0 controllers, add your lights into our system, create your own light configuration, the possibilities are endless with PLC2.0!
How the Infinitra ACB1 16 Button Controller works
The controller acts as the user interface for the Infinitra light bar system. When a button is pressed, the controller sends the command to the central control box. The control box then activates the corresponding output or adjusts the selected system setting.
For everyday use, that means the operator does not need to think about wiring paths or output channels. A button press does the work.
For example:
Press a programmed button to activate a specific output, such as a rear warning pattern or side-facing alley light.
Press the Front Cut-Off button to instantly deactivate all front-facing light modules.
Press Mode to move through available patterns.
Press Intensity to change the brightness level without altering the selected pattern.
The controller includes 16 total buttons, but not all of them serve the same purpose. Some can be programmed, while others are dedicated system controls.
Button area | Function |
Row 1 | Programmable buttons |
Row 2 | Programmable buttons, except Front Cut-Off |
Front Cut-Off in Row 2 | Dedicated button for disabling front-facing modules |
Row 3 | Dedicated Speed, Color, Intensity, and Mode controls |
Row 4 | Programmable buttons |
In total, the controller provides 11 programmable buttons and 5 dedicated system buttons. This gives the setup a useful balance. The programmable buttons can be matched to common lighting needs, while the fixed controls keep core functions consistent every time.
Physical setup and connection
The Infinitra 16 Button controller is designed to connect cleanly into the larger light bar system. It comes pre-connected to the central control box using a 4-pin screw-collar connector.
That connector matters because it gives the controller a secure physical link to the control box. The screw-collar design helps prevent the connection from coming loose from vibration, movement, or normal vehicle use.
The controller can be mounted using the provided bracketry in either of three ways giving you a fully customizable mounting solution:
Mounting option | Best use |
Flat (Fixed) configuration | Good for a stable, permanent position where the controller does not need to move |
Swivel (Vertical) configuration | Good when the operator needs to angle the controller for easier reach or visibility |
Universal Bracket Configuration | Good for custom installs on vehicles that dont have a standard mounting location |
A fixed mount may work well in a vehicle where the control panel has one dedicated location. A vertical swivel mount is helpful when seat position, glare, or cabin layout makes viewing angle important.
Power setup is just as important as the physical mount. The controller should connect to the same ignition power source that operates the main power relay. This helps the controller and main relay behave as one system. When the vehicle ignition power source is active, the control system is ready to use. When it is off, the system is not left powered separately by mistake.
A clean setup should focus on three things:
Reach
The controller should sit where the operator can press the buttons without stretching or looking away for long.
Visibility
The button backlighting and labels should be easy to see in both daylight and low-light conditions.
Security
The bracket, connector, and wiring should be mounted so they do not shift during vehicle movement.
Key features that make the controller easy to use
The main benefit of the Infinitra controller is that it separates common lighting actions into simple, repeatable controls. Once the programmable buttons are set up, daily operation becomes very direct.
The 11 programmable buttons give you custom control
The programmable buttons include all buttons in Row 1 and Row 4, plus Row 2 except the Front Cut-Off button. These buttons are used to activate corresponding outputs in the central control box.
A practical setup might look like this:
Use case | Example button assignment |
Rear warning | A button assigned to rear-facing modules |
Side warning | A button assigned to left or right side modules |
Scene lighting | A button assigned to steady illumination |
Low-profile operation | A button assigned to reduced output use |
Special response pattern | A button assigned to a specific mode or output group |
Each output circuit is rated for up to 5A, and the total combined system limit is 30A across all outputs. That means button planning should include electrical load planning. If several outputs may run at the same time, the combined draw must stay within the system limit.
Front Cut-Off gives fast control over forward light output
The dedicated Front Cut-Off button sits in Row 2 and instantly deactivates all front-facing light modules.
This is useful in situations where the light bar still needs to remain active, but forward-facing light would be distracting or unnecessary. For example, when parked facing traffic, reflective surfaces, a garage door, or another vehicle, cutting the front modules can reduce glare while keeping other warning zones active.
Because this button is dedicated, it cannot be reassigned. That is a benefit in regular use, since the operator always knows where to find it.
Row 3 keeps system controls consistent
Row 3 contains four dedicated controls:
Row 3 control | What it does |
Mode | Cycles vertically through pattern list, Modes 1 to 32 |
Color | Cycles horizontally across color sets, Columns 1 to 4 |
Speed | Toggles flash rate between 50%, 100%, and 200% |
Intensity | Toggles brightness between 20%, 50%, and 100% |
These buttons cannot be reassigned or modified. That fixed layout makes the controller easier to learn. If multiple operators use the same vehicle, they do not need to guess where the speed or brightness control has been placed.
The Mode and Color controls work like a grid. Mode moves through the list vertically. Color moves across the color sets horizontally. This makes it easier to reach the desired combination without needing a complicated screen or menu.
Speed and intensity are also simple toggles. Press Speed to move between 50%, 100%, and 200% flash rates. Press Intensity to move between 20%, 50%, and 100% brightness.
For example, a bright daytime setup may use 100% intensity. A nighttime or close-range setup may use 20% or 50% to reduce glare.
How to add Additional Lights to the ACB1 Controller (Grill lights, Underglow, Strobes, etc)
There are 3 easy methods to connecting other auxiliary LED lights to the Infinitra ACB1 Controller. This allows you to operate the entire emergency light system with one easy to operate controller!
*For easy indentifcation, pressing a button on the controller will illuminate the corresponding channel on the wire block inside the ACB1 Control box.
Direct Connect. Simply Identify which channel you want to connect your external/auxiliary LED lights to, for example you want your front grill lights to strobe when you press the STROBE 1 button. Since the controller is factory set with STROBE 1 button set on channel 13, you would wire your auxiliary LED lights into light output 13 on the controller box.
Mode Set Connect. Connect your auxiliary LEDs lights to your channel of choice, cycle through the modes till you get to the OFF strobe pattern. Pressing the button the auxiliary LED lights are connected to will trigger only those lights, and not the Infinitra since it is turned off in this mode. Changing to any other strobe pattern will trigger the Infinitra.
INFINITRA Delete Connect. Connect your auxiliary LEDs lights to your channel of choice, then disconnect the wire going to the PLC2.0 card. This will disconnect that channel to the Infinitra overhead light bar but still control the auxilary LED lights.
How to program the buttons step by step
Programming the controller is easiest when the system is approached in order. Start with the physical setup, then decide what each programmable button should do, then configure button behavior.
Before changing settings, identify the buttons that can actually be programmed. Remember that Row 3 controls are dedicated, and the Front Cut-Off button is also fixed.
Use the included sticker sheet to customize the controller face to your specific needs. (*Remove the standard factory sticker first before applying new stickers to the buttons.)
Step 1. Confirm wiring and power
Check that the controller is connected to the central control box through the 4-pin screw-collar connector.
Make sure the screw collar is properly tightened. The connection should feel secure, not loose or partially seated.
Then confirm that the controller is connected to the same ignition power source that operates the main power relay. This keeps the controller behavior tied to the main light bar power system.
Step 2. Plan the 11 programmable buttons
Before pressing buttons, make a simple plan. Decide what each programmable button should activate.
A good layout groups related functions together. For example:
Row 1 for main warning functions
Row 2 for secondary or directional functions
Row 4 for scene lighting, auxiliary outputs, or less common functions
This reduces guesswork later. If Row 1 is always used for primary warning actions, the controller becomes easier to operate by feel and memory.
Step 3. Unlock changes if the lock-out feature is active
The controller includes a lock-out feature to help prevent accidental changes. The lock-out feature only works for the Infinitra overhead light bar, so no other lights on the vehicle will be affected.
Press and hold the Mode Select button for 3 seconds to lock or unlock changes to Mode or Pattern assignments, Color, and Speed.
When locked, those settings cannot be changed by mistake. Intensity can still be adjusted, even when the lock-out feature is active.
This is useful during normal operation. Once the system is set the way it should be, lock the settings so an accidental button press does not change the pattern or speed.
Step 4. Enter backlighting and mode configuration
To enter configuration mode, press and hold the Half-Sun backlight brightness button until the backlight flashes red.
This mode lets the controller show the current button behavior through illumination:
Button state | Meaning |
Illuminated button | Momentary mode |
Unlit button | Latching mode |
Momentary mode means the output stays active only while the button is pressed. Latching mode means the output turns on with a press and stays on until pressed again.
Step 5. Choose momentary or latching behavior for each programmable button
Use the illuminated and unlit button states to set the behavior that fits each function.
Momentary mode works well for brief actions. For example, a temporary signal, horn-linked light action, or short-use output can be easier to control when it only stays active while pressed.
Latching mode works well for ongoing functions. For example, a rear warning pattern, side warning function, or scene light output may need to stay on until the operator turns it off.
Practical examples:
Function | Suggested behavior |
Rear warning output | Latching |
Scene light output | Latching |
Temporary attention signal | Momentary |
Short-use auxiliary output | Momentary |
The best choice depends on how the vehicle and light bar are used. The goal is simple. Functions that should stay on get latching behavior. Functions that should stop immediately when released get momentary behavior.
Step 6. Set the pattern, color, speed, and intensity
Use the dedicated Row 3 controls to adjust the active system behavior.
Press Mode to cycle through Modes 1 to 32. Press Color to move across Columns 1 to 4. Press Speed to toggle between 50%, 100%, and 200%. Press Intensity to toggle between 20%, 50%, and 100%.
A practical setup might use:
100% speed and 100% intensity for high-visibility daytime use
50% speed and 50% intensity for general work zones
20% intensity for night operation or close-range use
These values are easy to change from the controller, so the same light bar can adapt to different conditions without rewiring or reprogramming the entire system.
Step 7. Lock the system after setup
After programming and testing, press and hold Mode Select for 3 seconds to lock Mode or Pattern assignments, Color, and Speed.
This reduces the risk of accidental changes. Since Intensity remains adjustable, the operator can still adapt brightness during use without opening up larger setting changes.
Operating the Infinitra light bar feels simple in daily use
The controller makes the light bar easier to operate because it keeps the most frequent actions close together.
Imagine a vehicle arriving at a work area. The operator can press one programmed button for rear warning, adjust intensity for the light level, use Color or Mode if a different pattern is needed, and use Front Cut-Off if forward-facing light should be disabled.
There is no need to remember a long sequence. The controls are separated by purpose:
Programmable buttons handle assigned outputs.
Front Cut-Off handles front module shutdown.
Row 3 handles system-level changes.
The lock-out feature protects the setup.
Backlighting helps show the button mode during configuration.
That layout is especially helpful when the light bar needs to be used quickly. The operator can build muscle memory around the rows. Primary functions can live in the same place every time, while dedicated system buttons never move or change.
A final setup checklist
Before considering the installation complete, run through a short checklist:
The 4-pin screw-collar connector is fully seated and tightened.
The controller is mounted in a fixed or vertical swivel position that is easy to reach.
The controller shares the ignition power source used by the main power relay.
The 11 programmable buttons have clear assigned functions and overlays are in place.
Front Cut-Off is tested and disables all front-facing modules.
Mode, Color, Speed, and Intensity controls work as expected.
Momentary and latching behavior match the intended use.
Each output stays within the 5A circuit rating.
The combined active outputs stay within the 30A total system limit.
Lock-out is enabled after setup to prevent unwanted changes.
