No issues what so ever with the ones I installed... They stay plenty cool.. even in the Arizona summer heat... I tell you, they run COOL to the touch.... the heat sink is way over kill... And reality, very little is machined away to fit the Stock Buckets... I hate cutting Original parts, so I don't !!! Not a single failure in my application!!!!! See my pictures at the beginning of this LED install thread...
And the ones I have machined for friends... No falures so far.
