I like this write-up since I look at my poor truck and its lack of lighting. This could be a cheaper and easier alternative for adding lights to a car, but….there could be legal (street legal) issues, still expensive (LED strips) and I wonder how “auto proof” those LED strips our. In other words, how long will they last?
