well i have a 88 GTE 5spd, and i just started to have my exterior lights not to work. i changed out 2 fuses and then it popped again on the highway. so today i took another look and popped 2 fuses and by the third time it doesnt turn on. only my head lights work, i checked relays and i even changed relays and nothing, at first when i hit the brakes all the lights turned on, but then it stopped, i was wondering if it could be the safety failure box in the trunk? when i looked at it, it was all when and guess that can be the problem, also i hear the relay click when i turn it to the parking lights, but nothing only head lights work, and tails when i hit the breaks, dash lights are off and every thing else still works
