Alhambra light problem

[MARK REDMOND]

I have a seat alhambra 2002 and when I switch the car on it shows a warning light on which as far as I know means bulb out. But when I touch the brakes the light goes off. All bulbs seem to be working and dont know what else to try. Can anyone help?

Has someone put LED bulbs in instead of halogen? Does it have a high level (3rd brake light) and does that all work?

 

[MARK REDMOND]

Most of the high level light works but not it all. Sometimes it all comes on and other times does not

I'd probably start there. I can't remember the exact %. But if <xx% of your high level is on, it triggers the warning light. I can't remember how much of mine I lost... think it was 60% which would make sense as I believe 50% or more is an MOT failure.

I replaced the high line brake light now works 100% but symbol still coming up. I have replaced every bulb in the rear of the car and still coming on until I hit the brake pedal and it goes off.
