Just a POI; there are tens of thousands of autos out there from various makers with closed in light housings that don't melt down. Don't think air flow is 'it'. LOL, yes, there are even more with open air, gasketed systems that haven't had problems with water either. Something other than the twin H7 prolly would have been a good way to go...Wanderer said:Howdy,
I believe the root cause IMHO is that the headlight connector was poorly designed to be used in an area with limited air flow. Because of a "water" concern the back of the headlight does not get enough air flow to keep the OEM connector cool because it is part of the load. The point at which the connector and the bulb plug in is the load, that’s where the watts/power get consumed and that is where the heat is generated. By moving the OEM connector away from the load it is no longer part of the load and basically becomes just like a piece of wire in the harness. Ceramic is pretty much impervious to heat, think Space Shuttle, so the watts/power that is being consumed is isolated at the load. The plug and play replacements also have a higher gauge wire further isolating the load.
