I've not got around to replacing them yet, i see it is a common problem and the only cure is to connect them to the electricity mains!!! I could get plastic ones but i thought that the VW ones were so lovely and sexy, set it off a treat..... I know that this is feminine and none of you guys will understand but its a bit like wearing nail polish, a little detail that can set off the outfit a treat!! Next time you are out on the pull boys.... take note, did she go that extra mile?
