I purchased the light kit based on a review by a prior customer. He mentioned that his brake lights were blocked by his motorcycle. I decided to buy them based on his recommendation. The light kit came in the same shipment as my carrier. Appears to be very well made and heavy duty. Very clear instructions, and a YouTube video helped, also. The hardest part was screwing the base plate. It was a little hard to get the screws started. I am pretty sure it won't ever come off. Took about 10 minutes from start to finish. My truck brake lights are only partially obstructed, but the extra safety in South Florida is important. The lights are very bright and worked the first time (a testament to the great instructions).
