Why are the bottom pair of lights Lite at ignition?

Why is my 4 wheel drive light not engaging?
If you don’t shift it into neutral, the 4wd light will continue to flash and won’t get into gear. Seems to be a common occurrence on these trucks. Dodge dealers recommend engaging 4-lo, then back in 2-wheel drive, then back in 4-wheel drive hi (4H). This sequence apparently resolves the problem.
Why are the green lights flashing on my Mk 1 / 2?
Assuming it’s a Mk 1/2, the green lights are flashing because the system thinks that the front axle freewheel unit is still engaged and is trying to disengage it (or vice versa). The system is operated via vacuum created by running engine (for petrol models) and is controlled by switches and electric solenoid valves.
