High quality
Color: White Combo Beam
Excellent quality. By far the easiest wiring installation you deal with for lights. I would definitely buy them again.

Covers all your lighting needs
Color: White Combo Beam, Color: White Combo Beam
This set of lights was the perfect size for my Polaris RZR. Factory headlights were useless, even after changing 1200 lumen bulbs to 6000 lumen bulbs. This set of Aux beam lights are heavy well built, housings are powder coated and very solid, all hardware s stainless steel. The high low beam option works great when dealing with on coming traffic. They see you switch to dim and you don't get high beams flashed at u. Plus the high/low are seperate switches so u can run both at the same time. They are very bright and have excellent penatration. 👌 only thing wrong, directions included were for installing a light bar (bar only) nothing about lighting or wiring. As I am a Polaris mechanic this wasn't an issue, in fact didn't look at the instructions till I was done to even notice it was the wrong instructions in the kit.

Work great as headlights.
Color: White Combo Beam, Color: White Combo Beam
Super bright and fantastic build quality. Using them as headlights since they have the High/Low beam function. Wiring harness is exceptionally long.
