Great pre and post sales support. Installation was a bit tricky for me. But after reviewing some online content it went in pretty good.
Easy installation. A lot brighter than stock lights.
The older I get, and the more tinted my truck windows become, the greater the need for additional reverse light. The lamps really do the job with much more white light that the factory lamps.
Extremely bright! Easy to install. Worth every penny.
Very bright! As you can see from the picture posted. The bottom is my stock bulbs and the top is these bulbs. Literally looks like headlights.
