Hi all - I hope you can help.
I have a problem with my driverside brake light. Its on a Panda 4x4 1990 FIRE, where the brake light is combined with the driving lights (the ones that come on when headlights are on).

The bulb is definitely okay as it lights up when I put the main headlights on.
But it doesn't get brighter when braking, and if the headlights aren't on - then it doesn't light up at all.

The way the wiring is on my car, all the wires come to the driver side cluster - before continuing on to the passenger side...

Does anyone have any suggestions for sorting this?
Any help much appreciated.

Isn't it a double filliment bulb? I.e. it's possible the second filliment has gone but the one for the driving lights is fine?

Ahhhh.. ..hold on, will replace and confirm.

Yep - all fine now. I had originally assumed the bulb was fine - not clocking that it was possible for just 1 of the two filaments to go. (For some reason I'd assumed if one went then they both would).

But wierdly, when I tried the passenger side (functional) bulb into the drivers side - it didn't work properly either - this time just shining at 'braking strength' when the lights were on, and not changing when the brake pedal was applied.

But a trip to halfords and £1.99 later - all is sorted. Dunno what all thats about.

Thanks for the help - now off to show off my new brake light....

lol, nice one I wasn't sure if one fillament ever went on its own but thought it was worth a try
