We used this Cyfie 12V LED Trailer Light Kit to refurbish our 1975 boat trailer, and we are very impressed with it! The kit came with everything we needed to get the job done, which made the whole project much easier. The lights are a great upgrade for our older trailer, and I love that they are LED and submersible since we use the trailer for our boat. Everything we needed was included, so we didn't have to run around looking for extra parts. Overall, we are very happy with this kit and would definitely recommend it to anyone fixing up an older boat trailer!
