My tail light buckets look like new but could be connections between the tail lights and the front maybe, all the sockets and the 'local' plugs have been cleaned. It is mainly in the sun of summer i have issues with people. Kinda think it's that most are used to those glaring LED lights and not paying attention anymore these days. But this is a great tip for someone with not so bright buckets.
Got a roll of it at the auto parts store - summit has it as well
