Blue lights on there typically mean the handbrake is fully applied when solid blue, and in the process of being applied when blinking blue. Cars have also been known to just be flashing anyway even though the brake is fully released and fully in motion.
Handbrakes are the white lights i seen em come on at hoboken when they were doing there brake test
If you're talking about white lights on NJT's equipment, I believe those are lights indicating the cab signals are cut in for that cab car/locomotive. Blue lights are handbrakes, red lights are doors are open on that car, yellow means >25?psi in the brake line(cylinder?), green means <25?psi in the line/cylinder?.
...or if you're talking about PATH, then sure, I don't have a clue about the PA5's. I don't go to Hoboken (via PATH at least) anymore when I live a block away from Newark Broad St.
