Engineering & control
- Fixed main-beam color: 4500K white, yellow or amber
- Individual emitter dimming

- Modular TIR optics
- Bluetooth 5.3 / Race iOS app
- CANbus keypad
- 24 programmable presets
Five interchangeable individual optics let you tune the beam and replace an optic in under five seconds. Solid hardened-polycarbonate TIR optics sit in precision 6061-T6 billet aluminum bezels with bayonet locking and O-ring seals inside and out. The five individual optic designs are distinct from the complete-bar Spot, Combo and Flood configurations.
The thermal design removes the insulating dielectric layer from the LED-to-heat-sink path. The solid copper PCB is metallurgically bonded to a cold-forged pin-fin heat sink, with durable nickel plating. Temperature monitoring at every module supports active thermal management.
Interchangeable optics establish the base coverage. Individual module control lets you adjust relative output to change beam balance dynamically while driving. VHO main-beam color is fixed by the emitter you order. RGBW backlighting is controlled separately. Electronic adjustment changes the contribution of the arrays and modules; it does not move or replace the optics.
Power and current limits can be set in both the app and the light. Within the configured limit, the controller varies power across modules behind different installed optics to emphasize spot, flood or a blend while driving. This lets you put the available electrical capacity toward the coverage you need.
Plan your installation
Nominal size describes the product family. Check the actual dimensions above against your mounting space, including brackets and cable clearance.
Match your vehicle's available electrical capacity, wiring and protection to the selected light. Calculated maximum draw for this model is 77.3 A at 12 V. Confirm the required harness, compatible controller, connectors and circuit protection with Race Lights and confirm which installation parts are included before ordering.
