Ok, so the bulb ends in the number plate light were corroded and when I removed the bulb, the bulb holder spade connection snapped off!!! So, I went and got a replacement from a scrappie (only £3) soldered it back in place, got two new bulbs (only 43p), put them in and now both number plate lights now work! (#feelingsmug) Only issue is that the light has still went out on the dashboard!!!!! Someone please help! Craig
