What year?

I don't know this model, but on my Chevy (with a real transmission not a 
slushbox :) the LEDs indicate if the hubs are locked in.  Thus when I switch 
to 4WD the lights don't come on right away, and when I switch back to 2WD the 
lights stay on until the hubs unlock, which can be quite some time latter 
(generally when I next stop).

I'm sure my S10 has completely different parts from the truck you are looking 
at though.   Still my first though would be to find someplace where I can use 
the 4WD, and make sure the front tires really are spinning.   If they are 
really spinning I wouldn't worry about those "blinken lights"
