Height tail lights won’t go off

Hi guys the Height tail lights on the back of my cab won’t go off , does anyone know what might be going on here.

stuck misadjusted brake light switch

Thank you I will check that out. It’s strange it goes out after about a minute every time I switch it off.

Not sure what year your GEM is but in my 2013 there is a timer that turns off all the lights after a period of time after removing the key even if they are left manually switched on.

Thanks for the info. That’s what seems to be going on.
