These replaced my older sensors and worked great. Easy installation but the lights are upside down if you use the same brackets. I used some velcro and it worked great and the lights are on top just like my old ones.
This kit made installing the springs easy. I bought a few parts at the hardware store because the person who attached the previous springs had rigged up something a bit non-traditional. I wanted the install to be easy, so I used what was already in place and replaced what was necessary (springs and pulleys).. I might buy another set just to have as back-up...
