Had a trolley jack in my boot the other day which smacked into one of the bulb holders bending two connections and making them touch, this made the rear brake light fuse pop. replaced the fuse and now the rear lights are going crazy (when i indicate they all flash/glow at same time etc.)

Points to an earthing problem but it should only be the brown points on either bulb holder plug earthing (but according to rac man pins 2 and 3 are earthing as well?

Im pretty crap with electrics but he reckons my fuse box is throwing a spaz?

anyone got any suggestions of what i should look at?

My runarounds broken down at the mo so need the cos for work tomor!

thanks.
