My son has a '99 206 and the other day I noiced that the n/s brake
light was not working. A few days later, before I could get out to buy
a replacememnt bulb I noticed that neither of the main brake lights
were working (high level one is OK). Got two new bulbs and went to fit
them but there was definitely nothing wrong with the old ones (replaced
anyway). They still didn't work. Checked forums etc and cleaned the
contacts (which seemed ok anyway). Still no joy. Checked fuses 11 and
12 and they are both fine. Still only have high-level brake light
working so it's all a bit dodgy. Are there any other fuses associated
with brake lights (although all fuses seem fine)?

BTW what is the red rubberised button in the engine compartment behind
the n/s shock absorber top?

Any suggestions???

Thanks, RB
