I put in some higher wattage H4 bulbs in my 93 Honda del sol about a
year ago and they've been fine until recently when they started turning
off and on by themselves. To make things worse, they completely died on
me now. The high-beams still work fine so I'm driving around with my
high-beams on at night. This doesn't make oncoming traffic very happy.
I've tried wiggling the connector hoping maybe it was just a loose
connection but they still don't work. I tried replacing the bulbs and
that didn't work either.

Can anyone help me diagnose what the problem is so I can fix it? I'm
handy with fixing things but I don't know anything about
troubleshooting electrical problems.

Thanks for the help.

 

Did you check the fuses? also you may have burned out your harness.
