Is this normal? These reverse lights stay on for 10 minutes after I exit my car and lock it up. Not full brightness, just a dim glow.

 

No. Someone's done something.

At a guess, fitted LEDs.

 

^^ Agreed. The usual downside of fitting aftermarket LEDs is that they tend to stay on for long periods of time after the car is shut down....

 

I witnessed the same thing. I installed 10 watt LEDs, believing that would present a sufficient load, but they remained on, although dim. Removing one and replacing with original bulb eliminated that. I picked up an "experimental" bulb carrier from a wreck and will try soldering a resistor in parallel across the reverse light contacts and see if that eliminates that problem. Many LED kits include that resistor.

I also replaced the entire interior lighting with LEDs, and they work perfectly, with no "constant on" condition.

 

Ha I'll bet you guys are right I've been there too ! Also bewere of the positive earth frame on the back of the tail light cluster as touching that on the boot/trunk frame is a quick way to fry your RECModule ! It has a fuse but with mine it blew both the fuse and recm.
