Main Beam Light On Dash Not Working.
Posted 24 October 2020 - 08:24 AM
Thanks in advance.
Failed mot yesterday for a failed bulb, sure it was working when I checked everything last weekend! Anyway, it’s failed for that plus the ‘tell tale’ on the dash not working. Before I start working out what type of bulb it is on the dash etc is the dash bulb linked/part of the circuit of the actual headlight bulb? In otherwords, when I replace the headlight bulb Will the dash bulb probably start working again?

Do you have headlights which are sealed beam or Halogen bulbs ?
Additionally, what instrument panel do yo have as clocks - the old 1 or 3 clock binnacle offset - or a 2 or 3 set in front of the drivers wheel ?
They use different bulbs - hence this question.

The headlights are halogen, H4 off the top of my head, the dash is 3 in front of wheel.

Some dismantling required to access them then. The tell tale is wired in parallel, just a branch off the main beam wiring so it would work even if you had no headlights. It may well be the bulb, but might be the printed circuit or a poor connection somewhere.

Acess is from the large gap at the side of the steering column

Thanks to both, I’ll give it a whirl tomorrow.
Give the bulb holder a 1/4 turn and it should pull out the back of the guage. The bulb required is a 501 capless bulb
