Emergency lighting box

[ROYSTON]

When I disconnect the box, I get no headlight, but tail on all the time- I have, already pulled the blue / black from the relay so I can switch the headlight from the right controls.
What is the fix ?
Thanx.

L/Y to L/B, I shall give it a wizz.

Tail light still on full time.
