These things are BRIGHT!
Color: 4.5" Combo Light
After watching some videos, I decided to pick up these lights to go on my work truck. I work in a lot of remote locations across CO, WY, and NM. Traveling at night down dark highways and dirt roads can be a little stressful when wildlife is out. Not anymore with these lights! I can easily see anything in the ditches around me and at least 3/4 of a mile ahead of me. I’ve been running them for a few months and have had zero issues out of them. They seem to be super durable, easy to install with all the wiring included, look great on the truck, and you cannot beat the price to performance value. It’s also nice that the include yellow lenses to change the color of the beams for fog. Don’t waste your money on more expensive lights, these will get the job done perfectly for a lot less.

Set these up on an older Ford Ranger and a Toyota FJ. Worked out great on both. Good quality for this price.
