I was following a 60 reg Octavia and I noticed there was something peculiar about the brake lights. When applied the left brake light that lit was in the top of the light assembly, but on the right it was at the bottom. Just wondering whether the light units came from different model years or whether one was wired incorrectly.

I have a vague recollection that occurs when a bulb has blown - the brake system uses the fog light bulb as an alternative to the blown brake bulb
