So here I am driving just before dusk the other night. Getting a bit dark, think I'll turn on my headlights. They worked for all of about 1 second and promptly die in the arse. Left me in the sticks and no lights.

I've looked closely at the fuses under the ignition, all of them fine.
Is there a fusable link and relay somewhere on the headlight circuit that I need to check in case it's blown as well?
