Flickering Lamp-out warning light

I guess I could be looking at a new rev counter, but has anyone else seen there lamp-out warning light flicker on/off when you have dipped beam on and change sometime else electrical. Doesn't seem to do it when just on side lights ... which would be the most obvious time it would come on!

For example, flicking to main beam and back, wipers on/off, braking, etc. I also seem it once or twice when I've put the rear screen demister on!

I can't see any obvious problems outside, like a blown bulb or one that flickers, but I guess it could just be teasing me so stops when I actually look!!

cheers, Gary

If you go driving at night and press any of the 'raise window' buttons, even when the windows are closed, you will notice the headlights dim due to the increased load.

My guess is that you have a slightly bad power supply to the lights or in general (e.g. the alternator) that worsens this condition, and the bulb check circuit doesn't like it.

Check your charging rate with a multi-meter Gaz. Every item on and it should be more than 12.45v + on tick over across both battery terminals. If it's less than 12.30v + then the regulator needs changing...
It also does sound like the rev counter could be showing signs of potential failure though but they tend to just start to show a permanent warning light, it's not such a gradual failure.

Check the security of the side light bulbs in their holders too. Just one flickering on and off can give an effect of dimming and it might be just a coincidence that it happens when you have main beam on. A single wrapping of foil tape around the main body of the pegs on the bulb does the trick
