Some of you will know that I have been looking
for a replacement rear right hand side light
on my mk3.
Finally I managed to find one locally and replaced it
today, after I put it all back and probably was like
this before and did not notice it. The light bulb that
is used as a brake light and side lamp lights real bright
when the side lamp is on and goes dim when the
foot brake is depressed so really its working the other way
round. the left hand side works correctly.
What can be causing this, is this an earth problem?
