CHOOSE LIGHT OUTPUT COLOR:
Every SLIM bar uses a Spot & Flood pattern, blending a focused spot beam with wide flood coverage for a balance between distance and width.
1) White LED — Up to 15,000 lumens. Bright, powerful light for any adventure. Off-road use only — the white beam blinds oncoming traffic and isn't street-legal.
2) Amber LED — Up to 7,000 lumens. Cuts through dust, fog, snow, and rain far better than white light. Ideal for poor conditions. Off-road use only — the amber beam blinds oncoming traffic and isn't street-legal.
3) Dual Function: White LED + Amber DRL backglow — Full white beam (same as above), plus an Amber DRL: a daytime running light you can run day or night. Doesn't give off much light — just a bold amber backglow that makes your vehicle stand out on the road. Street-legal — won't blind oncoming traffic, so you can run it anywhere.
BUILD QUALITY:
- Reflector-style optics with CREE XT-E LED chips for consistent, efficient output
- Housing is UV black powder coated to protect against fading, corrosion, and weather exposure
- Rated for a 50,000 hour lifespan
