in the US these are sold as "Fog Light Only" but i know some are using as headlights. has anyone here tired them and if so how do you like them or how do they perform in our reflector headlight housings? i just put a set of LED's in from SuperBrightLED and they are not "tight" in the housing and am concerned they might come loose and fall out. looking at more of a "brand name" to see if they are any better. thanks.
