[MENTION=8029]BeerOrGasoline[/MENTION] or anyone else who haz, I was given a set for my low beams on my Silverado, I don't have the box in front of me but they have the large heat sinks and cooling fans, swapping these into GM trucks can I safely leave the dust caps off??? or should I still a few holes for air flow?? or just sell em lol. the light out put is pretty bad ass on my brothers truck but I'm not sure I agree with his theory of putting the dust covers on and hoping for the best
