I would like to ask if everyone has the problem of getting to the front side light (parking light) bulbs. Both or one of them don't come on everytime but the slightest tap on the glass and on they come. They haven't actually gone (obviously) and are either loose or have a dodgy element but i can't see how you get to them. The handbook is useless as a guide as it is so unclear. Can anybody help by describing clearly how you get to them? Thanks.
