when i posted a question about why my LED interior light wouldn't work i got allot of replies so i thought it would be worth while posting my solution :)
the problem was the led bulb will only light up when current passes through them correctly, unfortunately the carrier is set up a bit backward for led bulbs :L
useing standard clips and a bit of fileing i redirected the earth
the clips are ideal because they insulate the old tab from contacting the positive point on the bulb, but one side the plastic needs cutting of to make more room when the bulbs in
then i souldered a wire to the positive tip of the bulb, with a male clip on teh end for the cars positive feed to plug into
popped the bulb in and presto, crisp white light for my mini
hope seeing this helps people out :)
