Side lights come on when brake pedal is pressed

Not a problem on my Audi but my fathers FourTrack 2.8TDS.

The problem:

When you hit the brake pedal the side lights come on, the 2 in the front bumper, the 2 small lights in the head lamps and the lights over the rear number plate.

Could this be an earth fault or is it more likely to be a shorted connection somewhere?

Any ideas and any help much appreciated,

Kev.

check you've got the right bulb in.

A common cause for this is using a single fillament bulb instead of a dual one.

Sorted it out this morning.

It was a dual filament bulb and one of the filament arms had broken and was resting on the other, so hit the brake pedal and it power up the brake lights and this then transfered across to the side lights.

2 minute job - well it would have been if I didn't have to drill out the bolts holding the lense in place /ubbthreads/images/graemlins/frown.gif
