What Bulbs does the warning Light Cover?

[DeadZero]

Hey

 

Bulb warning light came on at the weekend, drivers side main beam was out, changed the bulb, but the light has just stayed on.

 

Goes off and on randomly,  stays off for a longer period if I start car with main beam on, but will come on again while driving.

 

Checked all the main bulbs, indicators , head / side/ rear and brake lights.

 

2007 SE VRS , Standard.

 

I take it this an MOT failure ?

 

Thanks

As far as I can tell looking at a wiring diagram: front side lights, tail lights + rear fog, dipped beam headlights/Xenons, brake lights inc high level.

 

Something makes me doubt that the warning light would be an MOT fail if all the lights themselves are functioning correctly, but I could be wrong.

Thanks Wino, I will go replace them all, so see if one is going faulty.

 

so the light is tripped if the resistance goes up?

No idea how it works, sorry.
