Gremlins got to my reverse lights. The bulbs are new and the fuse is good, didn't have my test light. does anyone know what color on the steering column harness the reverse light power is? I recall something mentioned about a piece on the inner firewall, how do I check this? :blah: Thanks

Back-up lamp, circuit no 24, wire is light green.

It is lght green ,it could be your Neutral Safety Switch allso located on your colum inside cab.

yeah, I'd check the neutral safety switch, if it is not adjusted correctly, the reverse lights could be on while you are in Drive, or some other gear.

Thanks to all, much appreciated!
