![]() I have the bulb warning light on. EVERY bulb on the car lights, if I had a bad contact would I get bulb warning even thought he relevant bulb was lit?
I have NCT (MOT) next week and even though no bulbs out, bulb warning light would be a problem over here (Ireland). Any ideas? I have double checked and everything works, high beam, low beam, parking lights, front fogs, rear fogs, high mounted brake light, number plate lights (both), brake lights all six indicators, reversing lights, everything lights.

![]() Have you recently changed a bulb ????
Have you considered the corroded plate lights scenario. ????? |

![]() No, no bulb changes. Might try the corroded contacts issue on the festoon bulbs on the number plate lights, I CAN see some misting/tiny water droplets in them even though both plate lights are lit.

![]() Remember if you have a brake light out the system compensates and will light the fog etc. Carefully check each bulb in the rear cluster.The side repeaters and reversing lights are not on the bulb failure circuit.

![]() Cherers PAB, good to know re the side indicators and reverse lights, as my reverse lights are LED but have been working for a year or so with no probs so its not a canbus issue.
With tool box sitting on the brake pedal, car in reverse gear with handbrake on, every light in the back of the car is lit, so no subsituting going on.

![]() I had LED lights that were fine for years but then I started to get flashing xenons..
it turned out to be my canbus friendly LED number plate lights were playing havoc with the canbus system. replaced them and my problems went away so I'd defo swap them out as part of a test.

![]() Hi,
I have the light on the dash illuminates every so often, if I use the passenger side indicator the indicator flashes very quickly, and the driver side flashes as normal, then all of a sudden the rapid flashing returns to normal, and the warning light goes out as well, so this maybe coincidence but I wriggled a black wire coming from the driver side rear cluster and the rapid flashing from the passenger side returned to normal, so I personally seem to have a bad earth somewhere on one of the light clusters at the rear. This maybe what you have, as it looks as though a bad earth will illuminate the warning light on the dash. |

![]() Thanks for all the suggestions.
Solved it the old fashioned way. I took out every bulb and re-fit them to no avail. Then out of pure frustration I performed a 'percussion adjustment' on the rear left light cluster and the ****** fault light went out!!!! Typical. ![]()
