Fog bulbs

[larry leung]

Fog lamps are a pattern of light thrown by a properly designed lens/reflector. It is a wide (generally approaching 90 degrees of spread) shorter range beam with a very severe upper cutoff. Changing the bulb color will do absolutely nothing to make a set of driving lamps act like fogs. Driving lamps project a generally narrow (typically 20 degrees or less) long range beam, no cut-off. The lack of cut-off is what causes the glare in fog/rain/snow conditions. 

BTW, the factory fogs, IMHO, stink. 

Not the answer you wanted but, at least you'll save some $$ and time by not looking.
