Rear Moretti Light

Having a problem with drivers side rear light.

Normal driving light not working. Have changed all bulbs etc think its a loose wire.
have reversed connection and light works but when break applied reverse bleeper comes on.

anyone any ideas who could have a look at it for me. Would have a go myself but afraid I make a rocks of it.
Recon it just needs wiring stripped and replacef

You have a reverse bleeper? Is it a dump truck of a Subaru we are talking about ????

Must check it again think it only makes the noise if you reverse connection on lights.

You have me there but am sure it bleeps when you reverse?????

Same sound as truck reversing but comes on when you break if wiring reversed
