I have aux LED lighting on my business 3500 DRW with a flat bed. Spot lights on the side and a bar light across the back. I used Rigid. They have been installed for three years now. No issues, all the bulbs still work and they are bright. I have not used the cheaper brands, maybe they are just as good but its a work truck and especially in the Fall, Winter and Spring there is a lack of daylight here and when you need light, I need them to work. We fix equipment, load trailers with them and so forth, so while expensive, well worth the money.
