Got a horse trailer, which seems to blow the fuse in my car for the 'Right Hand Tail Light'.
When using the trailer, it will blow the fuse (not right away), knocking out the rear tail light on my car, and the rear tail light cluster (not indicators) on the trailer.
I've followed the electric cable and it seems to be sound.
However, I've looked at the tail light holder (see image). It looks corroded. Could that be the reason is eventually blows the fuse whilst in use?
Is that likely to be the culprit? Am I better leaving the bulb out so that it doesn't blow the fuse, or leave bulb in?
Any advice appreciated as to whether I can clean it up or whether it needs a new holder.
