The switch on the transmission is bad. It usually looks like a bolt with two wires going to it. Check a service manual they are easy to replace.
Both a stuck reverse switch and shorted wiring can be causes for reverse lights to stay on. Under normal circumstances, the reverse lights turn off as soon as the vehicle is shifted out of reverse.
Either the reverse switch is defective or out of adjustment.

Where is the fuse located for the reverse lights
Check your fuses
Hi, did you ever find out why your A140 reverse light always stay on even in other gears, I have the same issue, i have checked the bulbs, replaced the reverse light switch and still have them always on..
Sounds like the reverse switch is either damaged, or wired backwards... Did you have your clutch done recently?
Reverse switch on trans. is, most-likely, broken or stuck on somehow. You need to check it and/or replace it.
Cracked electrical wire caused this to my car once.
Try bypassing the reverse light switch that plugs into the transmission. If your reverse lights come on, voila! Problem solved. Buy a new switch.
