My car never had one fitted, its a 1974 Mk2, so no reverse light on the cluster or even an aux one. All these years later I am going to fit one, following a near miss and a very bemused young driver (who could not understand car was going backwards yet no reverse light...).
I am not even sure if the gearbox has the switch. On the same page as the lovely shiny aux reverse light (carbuilder) are pull switches. Will this be ok when it comes to MoT if I connect the reverse light to a manual switch in place of having the automatic switch at the gearbox side. (the loom has the plugs for them, but I tucked them away when I fitted a new loom 5+ years ago).
