Can't tell how big the heat sync is Sam. Would it fit in the fog lit housing? Tired of blowing them and they don't really work anyway. Would this be a good cosmetic replacement there?

If you plan on running them long periods, and they get that hot, it might not be a bad idea to put more heat sync on them.

Its big, it wont fit there for sure.. measures 2.34"x2.37"
as for the Fogs, install HIDs John, you wont regret it, i have 5000K and i cant be any happier
they are projectors, so you dont have to worry about them being too glittery. as for the folour, if you wanna match the top ones go with 4300K, same as stock, but better output and no problems

yeah prolly is a good idea, i bought them for my trunk because my current sub box takes blocks all the light, with the new sub box coming soon that problem is solved
