that couold be cool bart... problem is the operating temp... only up to 85* C.. which translates to about 185* F... my vx regularly runs around 190* during the summer, i dont know what that translates to as far as the engine bay goes... next time i go for a drive ill measure the under hood temp and report back.. the lights i got are made to be mounted in grilles where high temps are common, so i figure they are ok to run in high temps.. so far so good
