What's the purpose for rear foglights?
I noticed that the innermost bulb holder is empty on my car's taillights, and doesn't appear to have a positive lead. I assume this is the location for the rear foglights. How difficult would it be to get a lead in there for maybe a second set of brake lights or running lights? May as well make use of the spot, eh? And I don't even really use my forward-facing foglights very often.
Be nice to get the knob light working with the front lights, though...
