The last few nights when my lights are on I'll be driving along and suddenly for no apperent reason, my bulb out dash light comes on. I've checked all of my running lights and they are good. When I turn the lights off and back on again the problem goes away, until the next time. Is this possibly a faulty bulb-out relay? If so, where is it located? If not, does anyone have any ideas what it might be? Thanks.
