CHOOSE LIGHT OUTPUT COLOR:
Each PRO bar is dual-color — a main beam plus a soft amber DRL (daytime running light) backglow.
Option 1 — White + Amber DRL
- White LED — Super bright, crisp white beam with plenty of light for any adventure. Off-road use only — it blinds oncoming traffic and isn't street-legal.
- Amber DRL — Purely cosmetic amber glow. Street-safe — gives off little light and won't blind oncoming traffic, so you can run it on the road.
Option 2 — Yellow + Amber DRL
- Yellow LED — Cuts through dust, fog, snow, and rain better than white light. Ideal for poor driving conditions. Off-road use only.
- Amber DRL — Same cosmetic amber glow. Street-safe — won't blind oncoming traffic.
- Combo Pattern: combined spot and driving optics offer a balance between distance and width
- Uses a TIR (Total Internal Reflection) lens, which is different from the conventional optics parts, which lose some light internally and produce glare. The TIR lens collects all of the light from the LED and directly leads them to where you need, drastically reducing glare and improving total efficiency.
- Higher light efficiency: brighter, longer irradiation distance
- Housing is upgraded to 304 aluminum. The surface is UV polyester powder coated to protect against UV, salt water, corrosion, fading and scratch resistant.
- Equipped with thermal management system that automatically adjusts the brightness output according to the external temperatures
