The 'exterior lighting bulb failure' indicator lamp has been coming on quite frequently, the problem usually being with one of the side lamps (same housing as full beams - light switch to position 1?).

Tonight, neither of the lamps will come on but the license plate lights come on fine, as do the instrument cluster lights. I don't think the problem is with the bulbs though, because the full beams come on when I push the 'combination switch' stalk forward, and I assume they're the same bulbs (?)

Anyone seen this happen before?

Also - does the orientation of the bulb matter when you insert it into the socket? Do they have polarity?

Side lights are not the same bulbs as the Main Beam, and no, they are not polarity sensitive

Right, I'm confused. The main beam bulbs used to illuminate 'dimly' when I turned the switch to position 1. I assumed that these were called the side lamps. I'm talking about the light marked with the star in the attached photo, just in case I'm using the wrong names/terms. :)

There don't appear to be any other bulbs blown, so am I looking at a fuse/wiring issue?

No they didn't. You have separate 5w lamps in there. Have you read the manual?

The Main Beam will be a H7, the side lights will be either be an all glass 501, or a offset pin BAX9

Well, this is embarrassing :) I''d read the manual a few years ago but didn't see the reference to the separate bulbs, and never noticed it when changing the beam bulbs. Thanks for the pointer!
