messing about with my car earlier and found this random green light floating around the steering wheel, what the hell is this i thought? then i remembered a thread when someone mentioned a luminated ignition barrel, so i thought id try my luck and see if this was what it was for! took out the plastic bit around where you insert the key and low and behold there was a slot for this little bulb to sit blimey, id discovered a nice little factory option ;) question is, how rare is it?
