Thanks Neil - I will bleed the system anyway but I'm asking if the switch should have brake fluid inside it or just air ?

it works off fluid not air, the braking system should have no air in it

I usually fill switch with a syringe, then put a small piece of cling film over end, then brim the t-piece with syringe to overflowing with kitchen roll around it to catch overflow, invert the switch and place end into top of fluid then carefully remove cling film making sure it is not damaged, always good to bleed as well but have done this before successfully without bleeding always assuming your switch is in the normal vertical position at the top of the system. :wave:

Thank you Edosan - apart from minor details that's exactly what I ended up doing before I read your post. Brake lights now work perfectly.
