Main beam (flash) switch works, but not lights ..any pointers FIXED

[Stridey]

My lights went out last evening, dip and full, but the flash switch does illuminate the lights if held down....

Flashers work.

Ive checked fuses, looked at wiring. No thorough testing yet.

Wondering what sort of things I should check now.

Sidelights working normally?

I'd probably start with the main light switch. Check either the output voltage on the terminals as you work the switch or the continuity with the feed disconnected.

Got the wiring diagram already?

Side and dip and full not working, only full if I hold down the flash switch.

i have wiring diagram...(and tester)

ordered new switch anyway. Checking relays.

Relay also strong possibility... I was trying to remember the circuit details to see how flashing with the flasher switch differs from main beam with the main switch...

Clean the spring clips which hold the light switch into the dash.  The lights earth through these, via the dash, and if they have a bad contact then your lights won't work.  Even disturbing the switch by removing it and then putting it back in may cure the problem.

Fitted new switch (superb next day first class delivery by Car Builder Solutions).

Works like a dream.

Did check contacts on old one, Mort, no dice, but made sure new one is doubly secure/tight.

Thanks to the club again, for speedy suggestions and help.

Phew!
