My reversing lights don't work and there's no power to the bulbs. I know there's a switch on the G-box, but is there another or only one on the box? Also, if I remove the box switch will the oil run out or is it sealed behind the switch? Does anyone know if you can get these pattern or only original, as they are not cheap. Thanks.

Hi, experience from other reverse light switches are as follows, you'll findit located on top of gearbox, usually with a clip on lead, flick off the lead, loosen switch with spanner, then undo, oil won't come out as it on top. Before replacing with a new one. use a little bit of petrol to wash it off, then plug back onto lead and press the switch with your finger, if it works unplug lead, screw back into gearbox and plug lead back in.
If you need a new one just order at for dealer, not expensive £12-20, replace as described above.
Hope this helps!!

It's definitely at the bottom of the box, as per photo, and cost about 37 Pounds Sterling, here.
