I have 78 280z that i have "up graded" to the crappy plastic lenses with the replaceable bulbs. I put in relays when i did the swap, and had absolutely no problems for a year and a half. Then a few weeks ago my passenger low beam blows. Not a big deal, my lights aren't that bright so I drive it with high beams for a couple of days until my driver side high beam blows. Bummer, so i replace both bulbs. I tested the lights and checked my relays, no problems, but as I'm pulling out of work that night i see two quick flashes and everything goes dark. I switch to highs, and see another flash, and I'm down to one high beam. I checked for frayed wires and bad connections, then replaced bulbs again. had no problems for a month, but tonight lost both low beams while pulling out of work. The only common element as far as i can tell has been the weather. Every time it has happened it has been cold and misting, like just before it starts raining. I'm not great at electrical, but I can usually fumble my way through. Has anyone ever had a problem like this before? What should I check.
thanks, Jason
