:) T-Plate, honda accord ex headlights not working at all, no dim lights, no main lights, no beam ligts. Back lights and interior dashboard lights working.. All fuses checked and are fine, changed all bulbs.. but no joy! Any ideas what it could be?

I had the headlight switch go bad on my old car. If you have a voltmeter or a test light and are very flexible, you can test for voltage at the headlight switch terminals. The switch comes after the fuse in the circuit (I am fairly sure), so if the fuse has voltage, that's the next possible culprit.

If the switch is OK, then you have a wire connection loose or a wire is broken. This is the hardest to find. But I say the switch is more likely because it gets the most use and abuse.

Good luck!
