Tail lights on all of the time.

[Liroka]

I've been working on my ol' boxeye; replacing the shock and opening the headlight unit to see why my headlight was pointing up and why it wouldn't adjust. I've put everything back together and now my tail light is constantly illuminated even when my lights are switched off. Aside from this there's no response (in the light) when I engage either the front or rear brake. I thought it might be a stuck brake switch but the light is definitely just 'tail light bright' and not as bright as when the brakes are engaged. I did also replace the rear brake switch as the original was a little corroded, though this was changed after I noticed the problem with the lights.


Any help would be greatly appreciated as I really don't want to spend another week stuck in A1 traffic!
