Headlamp issue

[Jelleyboy]

For some reason the left lamp is coming on but the rights showing no signs of life, took a cable from the working lamp to the lifeless one and it shows very faintly not enough to light up, the cables are in the junction boxes completely stumped with this one

Is it a 2-wire connection or is the earth return via the lamp body and chassis ? if it relies on the lamp body connection to the chassis then there may be corrosion causing a high resistance between the earthy side of the bulb and chassis.

ive just cleaned up these locations so they're shiny for the earth connection the other side that's working is the same

Have you tried swapping the headlights from side to side in case the problem is not in the wiring?

Temporarily connect an earth wire from that earth point right back to the battery.

 

If that isn't it, then your two or three connections to the bulb are wrong, or the bulb isn't earthing to the housing.
