I am with www.pbcheap.com. and you are exactly correct, http://www.pbcheap.com/car-lights Car led light are basically like anything else we buy. There is good, better & best. A good Car led light are made of
aluminum & high density plastic. This is due to the fact that there is an LED driver inside that lamp which makes it operate...that driver gets extremely hot so when the LED lamp is made of some type of metal, and "fins" as I call them..air can circulate around the lamp and cool it so it will not overheat and fail. Cheap LEDs are cheap they are avaialable and right now are giving LEDs a bad name, they do save you money on your electric bill but are not always the brightest as the cheap ones typically just have a bunch of "LED indicator lamps" clustered together inside the lamp itself. This is the inexpensive way to put a bunch of indicator lamps together put them into a lamp and give you LED light....Good ones will have very few LEDs and they will be big chips, with a photo optic lens on top of the chip to harness and expand the light so basically the bulb design is working with the chip to deliver clean crisp light!
