Just brought some P1 lights from someone off here, but have a few queries ...
Do i need any additional brackets from standard driving lights to fit P1 driving lights? Also when they arrived one of the brackets had been sheared off, so there was only 3, will this be a problem? or can they still be fitted? also there were 3 long screws attatched to these brackets wasnt sure if there was supposed to be any more? I have also brought some fog light covers how does these fit together?
On the back of the fog lights there are some wires which have been cut presumably so they can be re wired to lights. do i need any additional cables or plugs to attatch these?
Regards
