Hey! No need to get defensive just because someone has a legitimate concern and observation about the safety of these lamps. I was looking at some today and it clearly said on the back of them that they weren't for highway use.I changed turn signals-flashers,tail-brake lights,and all exterior lights to LED today. No problems at all.Next week-all interior lights!!! Some people know their limitations and try to discourage others from experimenting.I have yet to find my limitation so,therefore,my experimenting will continue. There are naysayers and then there are doers.I'm in the latter pile.
