I assume the part of the kit you are referring to is the heat sink at the base of each bulb. My only concern with these LED kits is that there is a greater heat build-up inside the already cramped headlight compartment. If these bulbs get too hot to touch in 20 minutes, will it be like an oven in there after a 5 hour trip? What are the chances of plastic and wiring melting?
