Hi i am in need of some help again!

After a rear wiper problem i had which is now sorted thanks to the forums i have noticed my rear high level brake light has decided to stop working

Could it be a fuse problem? if so which fuse would it be

Please please help

Thanks

Are the other lamps working? if so wont be the fuse, quite likely the light unit has failed as they seem to be prone to failing due to water ingress. If possible check the feed to the unit
