Yeah i'm starting to think that might be the smartest move. Wonder if i can find another that will bolt directly in without modifying the hole.
Glad i can use the tail light for power also just seems simplest. Need to find a good quick releasing connector for it.
Edit: After some searching i found this light that look like it might do the job
i measured the area of my light thats still installed it was like W 10.2" H 1" on the outside. Will that one i found fit ok? i can use some RTV sealant or something around its edges if there is any gaps.
