Mini Cooper light problems
 

I have a 51 plate r50 Mini Cooper that is having issues with the lights, the main beam randomly flickers on and off. I have fitted second hand lamps today to the car after hearing they could of been the issue, it hasn't solved it....any suggestions? If this is in the wrong section I appolgise

If you replaced the lights then you may have a connection issue. Do the lights flicker on rough roads or on any road?

It done it with old lamps, so changed them thinking it would help but nothing.
It does it randomly, like it'll do it then stop for abit then start again

Loose or corroded connections or fuse? Definitely the poser source.
