my gf's 95 honda del sol doesnt have a little buzzer reminder to tell when the headlights have been left on, which means i keep a second battery around to go jump her car with once every 2 weeks or so.. very annoying.. so im gonna put a buzzer in to remind her to turn the headlights off.. but im not quite sure how to do it.. so i figured id tap into the knowledge base here...

heres my idea so far...

a relay that draws constant power from headlight switch, switched power from the output wire on the "door" mode of the dome light and the acc out (87?) to a buzzer

my other idea was a relay that draws constant power from fused wire from battery, and outputs to the buzzer, the switched power from the headlight switch and grounds to the pin switch in the door.. so its only grounded when the door opens....

im open to suggestions.. as spike can tell you my relay wiring is a bit sketchy still
