Product Description

This kit is built for drivers who want more than just “extra light”—it’s about having the right type of light at the right time. The wide cornering beams handle your immediate surroundings, lighting up the road edges, trail lines, and hazards that usually stay hidden. Meanwhile, the spot beams punch forward when your high beams kick in, giving you that added reach when you need to see further ahead.

What makes it even better is how seamlessly it works with your truck. The lower pair behaves like your standard fog lights for everyday driving, while the upper pair activates automatically with your high beams—no extra switches needed. It’s a clean, intuitive setup that feels natural the moment you use it, whether you're driving through bad weather or heading off the pavement.

At the end of the day, this is about control, confidence, and visibility that actually keeps up with your driving. More coverage, smarter beam patterns, and a factory-style install that doesn’t look out of place. Baja Designs built this system for real conditions—and once you experience it, you’ll see just how limited stock lighting really is.
