2010 ASX RHS rear lamp no longer working
 

Hello.
RHS rear lamp no longer working however other lamps on circuit (LHS rear lamp + front parkers) working plus RHS brake light/s work. Not a fuse issue. Not a housing issue because bought a new housing to no avail (exact same issue). Indicator in same housing works but is on another fuse anyway. Presumably a wiring issue then. Anybody with same issue? Anybody had same issue and solved? Cheers
