Brake / Side light issue

[Soarer]

Hi all. I am hoping someone can help with a rear light issue. I have a 2012 SWB which has been very reliable until about 10 weeks ago. It started to blow brake light bulbs, about 4 over the course of 6 weeks, both sides. Then about 4 weeks ago (just before Christmas) the O/S brake light and tail light stopped working, when I removed the bulb I found that both filaments had blown, I put it down to cheap bulbs someone had given me, why else could it suddenly be blowing bulbs. So I decided to get a pair of good LED brake / side bulbs instead. I put them in this morning and the O/S LED brake / side lights still do not work, the N/S LED brake / side light works fine. I could not find a fuse listed anywhere, so I physically removed and tested every fuse in the engine bay and under the dashboard, every fuse tested good. Could any one give me some advice on where to look next for the fault. The wires appear to be tightly in the connector and I could see any rust on the metal terminal where the build clicks in. Any help will be greatly appreciated. Thank

Welcome to the forum.
I thought that there were fuses for the lights, but may be mistaken. Only things that I can suggest are checking that you get +12v to the light socket and that there's a good earth for both sides.
Does the high level brake light work?

Just removed some notes from this post as they applied to the M59, not the B9.

Hi

Thanks for replying. The high level brake light is working, all the lights on both sides work, it was just the O/S Brake & Side light that wasn’t. I check the voltage when I got home tonight and neither the brake or side light were getting the 12V to their terminals. I started to check all the cable connections were tight etc, prodded and poke about wherever I could see the loom, popped the LED Bulb back in and it worked. I think there is a poor connection somewhere that I must have prodded or poked on, so although it’s working again I won’t be surprised if it fails again.

I'm not saying you do but....

You find that if you sit with your foot on the brake for long periods (Traffic lights etc) the bulbs have a shorter life and the fitting / wiring can overheat causing a poor connection.

Brake lights were never designed to be on for long periods of time, that's why you have a handbrake.
