0 ThermoDog Posted December 30, 2020 Share Posted December 30, 2020 That light lets you know that air pressure has yet to reach cut off limit. It should extinguish when the air tank(s) have been charged, at which point you can disengage the park brake. It’s picture represents brake shoes locked to drums when illuminated. But it’s always been an indication for me that my bladder is full and it’s time to pull over and pull the yellow handle. Haven’t figured out what the yellow handle has to do with my bladder though...
