Daytona 955i

Hi all I'm having an issue with my headlights . If I switch the lights on
On dipped beam both lights work
If I switch the main beam on the right hand side light goes on main beam but the left hand light goes out. Any ideas ?

 

Swap the bulbs over, if the problem moves then, as above, the bulb has blown.
If it stays the same then it’s wiggly amps which is the work of the devil.

 

Or it could be a relay that's not working or has been removed.
