well I don't understand?!
these are the ones I HAD (now HID
)
even when connect to the fog light unit, unless it was clipped into place then it would not work! almost as if the metal body of the LED bulb WAS the ground! (well thats what I assumed!)
so make sure your LED bulb is actually FITTED into place, rather than being connected up to quickly see if it works if you see what I mean?!
