Hi there having a nightmare recently with my brake bulbs. They seem to be very temperamental with working then sometimes not. The bulbs work fine as I've tested them out. There's no logical answer as I've swapped them round had new bulbs fitted they worked for a few miles then they just stop, a quick fiddle around with them and there back working again. Sometimes it's just both that stop and sometimes just one, very random :/ anyone got an idea of what may be happening or a solution ?
