Ok still trying to sort the non operating spots on my 82 MK1. It looks as though it has had some sort of headlight upgrade at some point and the spots are triggered via a relay that sits on the inner wing near the battery, its connected straight to the battery and to one of the main beam wires.
Presumably this boosts the power of the lights.
I have bypassed the relay and the spots work fine so I can only assume its this relay.
Does anyone else have this? the relay is made by Durite? number 0-726-12 12V 15A
Finally how can I source a replacement?

?
cheers
