Parking light Indicator MK23

[10isBestmm]

Truck recently started having the parking light indicator stay on for 2-3 mins when releasing the parking break.
Truck rolls and brakes aren't engaged and the air tanks are full. (110-130 PSI)
Anyone have a similar problem?
It happens during warm and cold temperatures.

There is a switch on the parking brake valve more than likely. Pull the valve. Check for power going thru it with the valve disengaged. If yes replace the switch. If no we will chase that gremlin if needed.
