ive noticed on my quad lamp that the centre lights only come one when i have full beam on. yet the switch on the dash that does the rear high intensity has 2 settings. pushing half way does nothing, but pushing it fully in turns the rear lights on. a friend of mine has a mk1 and he can turn the inner lights on his golf independently (hope i spelt that right). has mine been re-wired? or is this just a different set-up on the light switching?
