Very pleased with this led tail light. I did not want to add a run/turn/brake controller to the rats nest of wires I already have under my seat. I have a trailer wire harness and converter under there already. But I did want a brighter tail light. This product fit the bill. Installations could not have been simpler. Remove oem tail light, unplug from fender mount, plug new adapter into oem fender mount (new light comes with two, your choice). Mount new light with oem mount screws and your done. Tail light is much brighter than OEM and brake light is scary bright and I can always add a run/turn/brake controller later if I choose to.
