Strange headlight

hi guys, i dunno if you can help me out
i was driving home one night and i stopped to get petrol, after i got back in the car i put my key in and started my car and the car through up an error "right dipped headlight" so i got out and changed the bulb and the error was still there and the old bulb was still fine and i tried different combinations and still the error still there.

all the other lights work fine just that one bulb, any suggestions guys?

i havnt got xenons jus standard H7 bulbs... i think ill go park my car in the garage and try and figure the problem out now, ill let u guys know how it goes

fixed the problem, turned out it just needed a couple of sqirts of wd40 in the connectors to make it all work properly
