Technical Brake light not working

[the frog]

My drivers side brake light has given up the ghost, the bulb looked to have blown so thought that was the problem - PITA to get too! Stupid design of inspection hatch. Anyhow the bulb was replaced and didn't solve the problem, ok duff bulb, tried another one and still nothing????

I suspect the light unit has a circuit board inside which has failed????

Any help appreciated.

its just the one brake light not working?. both mine went out and it was dirty/coroded brake light switch at brake pedal, took it off and cleaned it with screwdriver blade & hey presto they were working again

Sorted, for some reason the bulbs weren't seating properly in the holder.

I need a new rear light d/s still anyhow as it's cracked. Anyone breaking a multipla?

Hi-Just joined to say how I just solved this problem. After 30 minutes changing with new bulbs and then replacing old bulbs I found the problem to be intermittant with both old and new bulbs and both sides, that is changing left for right. So bulbs worked and didnot work, that is in a locked position...With someone pessing and leaving the brake on I fiddled with the bulb holder turning anti clockwise to undo then clockwise to hold, in the locked position sometimes they worked and sometimes they didnot; even with a squirt of WD. SO MY CONCLUSION IS POOR ELECTRICAL CONTACT WITH BULB HOLDER AND LIGHT ASSEMBLE. Any suggestions of better spray than WD?

Electrical contact cleaner from Maplin, much more effective than WD40 for electrical connections. It's around three quid.
