These lights are super bright and fantastic, especially for the price.There is no complaints I have with these lights.We needed rear spot lights for the back of our race car trailer. At night in the pits at some tracks it can get real dark. That is not good when you're trying to get your car ready for the next race. So we ordered these lights to put onto the rear roof of the trailer, so they can aim down behind the trailer and we can see what we're working on. We did away with the switch they came with and wired it to our own switch and electrical to the trailer. (Nothing wrong with the stock switch, we just didn't want it setup that way.)These are the best spot lights we've ever had. We've had other race teams ask about the lights, because how nice and bright they was. They were stunned when I said I paid around $30, a lot of race teams spend hundreds of dollars on spot lights and they're not as bright as these.For durability, they are super durable and weather protected. We put these lights on the roof of the trailer in November of 2020. Since then they've been through 3 snow storms, tons of thunderstorms, 70 mph winds, for hundreds of miles going down the road etc... Still work amazing, not 1 issue with them.They worked so good we ordered more, to put in our yard, so when we get back from the races at night we can see easier to back our hauler into it's parking space. They're also in the weather 24/7 with no problems. We kept their stock switch though.Here's a picture of them on back of the trailer. I'm usually to busy at the races and keep forgetting to get a picture. I will try to remember this race season to show how bright they truly are.UPDATE:Updated with a picture of the lights on at the race track. The lights have now been on the trailer for over 2 years now. They are exposed to the elements, rain, wind and snow storms. Never had an issue with them yet. Flip the switch and they turn on after sitting for the winter months. Never had to do any work on them.At this race we had another team ask about the lights, wondering again how much we paid for them. After I told them and how long i've had them, they were STUNNED, that I only paid $30 dollars for them. They paid $300 for their purpose built race lights and they're not as bright as ours. Mind you we only have the 20W you can get 50w for $39.
