    Default Third brake light

    Ok for my first technical post....

    My third (LED) rear brake light does not work and makes the computer thingymajog say "check third brake light".

    I have tested the LED strip and that works ok, however there is no 12v feed to the connector.

    I have traced the wire back to the multi plug behind the left hand carpet wal in the boot, but there is no 12v supply there either (there is continuity in the wire)

    Does anyone know whether there is a relay or a fuse which controls this third brake light, and if so where abouts it is? I could jumper the wire with another brake light wire to get the third light working, however this wont cancel out the computer message about it not working.

    Help please........

    Someone once told me my Omega probably had 1 fuse covering all of the lights at the front, so I took a look and found there was a separate fuse for each light function - so 10 fuses just for the front lights. Using that same principle its highly likely you have a fuse just for the 3rd brake light. Look in the fuse box, see if you can decipher which one it is, or if you can only decipher which fuses are for lights but not which lights in particular, then check all of these and you may stumble across a blown one.
