RACE LIGHTS / THE ZENITH PLATFORM
ONE SYSTEM.
YOUR BEAM.
Quick-change optics. Individual emitter control. Intelligent power allocation. Explore what changes your drive, then go deeper when you need the details.
INSIDE ZENITH
THERE’S A REASON
FOR EVERY PART.
Start with what it does for your drive. Open the engineering detail when you want to know how it works.
ZENITH / MODULAR OPTICSTHE BENEFIT
Change your beam.Keep moving.
Five interchangeable optics let you tune the coverage for your route. The bayonet-locking bezel is designed for optic changes in under five seconds, with O-ring seals inside and out.
GO DEEPER +
The solid TIR optic is made from hardened polycarbonate. A precision 6061-T6 billet aluminum bezel uses a bayonet locking mechanism; the published release rotation is 15 degrees. Five quick-change individual optics establish the base coverage. These individual optic choices are distinct from the Spot, Combo and Flood whole-bar ordering configurations. Choose compatible parts for your light.

EXPLORE A LIMITED POWER BUDGET+
Where the available power goes matters. Try prioritizing reach, width or a blend while keeping the same example budget.
Choose a priority to apply the example. Manual edits leave this example mode.
For this example only: 01, 02, 07 and 08 represent width; 03–06 represent reach. These are illustrative optic assignments, not identification of the photographed optics. Equal capacity per position is assumed; percentages do not represent measured watts, amps or light output.

Ratings vary by model. Maximum light output and power depend on operating conditions and settings. The table does not represent independent testing, sustained output or measured system efficacy.
02Optical & emitter architecture
+
SHO, UHO and Hybrid
SHO provides white main output. UHO and Hybrid configurations add a separate amber or yellow channel for adjustable dual-color output. White + Amber and White + Yellow are distinct ordering choices.
Control and color
Five interchangeable hardened-polycarbonate TIR optics establish base coverage. Individual module output and dual-array control adjust the resulting beam electronically, with color control on compatible dual-color configurations. Dedicated RGBW backlighting adds the visible signature independently. LED architecture varies by model.
03Thermal path & material choices
+
Mechanical heat management
The solid-copper PCB is metallurgically bonded to the cold-forged pin-fin heat sink. Dielectric ablation removes the insulating layer in the LED-to-heat-sink path, creating a continuous metallic route for heat. Nickel plating provides a durable finish. The design gives heat a direct route from the LED toward the exposed pin fins.
Electronic thermal control
Active thermal management is divided across emitter zones and supported by secondary thermal shutdown. Output can change with temperature and operating conditions. Every emitter module is temperature-monitored. Gold plating describes the electronics finish; it is separate from the copper thermal path and nickel-plated heat sinks.
04Connected control & compatibility
+
App + physical controls
Compatible Zenith configurations support Bluetooth 5.3 app connectivity and a CANbus keypad. Published features include individual emitter dimming, RGBW backlight control, 24 app presets and voltage data logging.
Explore the Mobile AppChoose for your hardware
Feature availability depends on the light, firmware, app and controller. CANbus keypad support is not a claim of universal factory vehicle integration. The R3 Uni Pod is a separate PWM-dimmable auxiliary product; this page’s Zenith app and CANbus architecture does not apply to R3.
05Chassis & mounting materials
+
Purpose in every cut
CNC-machined billet aluminum forms the chassis and bezel rings. Black chassis and black bezel rings are standard; custom powder coat colors are available for the rings. The mounting system pairs nickel-plated 316L stainless brackets with Grade 5 titanium hardware. Gold-plated electronics serve a separate electrical role.
