Freightliner no brake lights

Should be a brake light switch on the parking brake. Look for 2 air switches, 1 controls the low air light/ buzzer, other one controls brake lights. The switches are different, one normally closed, one normally open. They’re marked accordingly. I had more info on them, but it got lost. Maybe someone else has more info, maybe Dealer can help.

 

I don’t know, myself.My 01 Fld has then on parking brake.

 

Maybe there’s another somewhere. Maybe on the brake valve? I’m thinking that’s the one you replaced under the hood? Maybe another instead dash, on or near brake treadle valve. Sure you got the right switches in the right place? Do brake lights come on trailer? Straight Truck? Check the lights at back of frame, maybe. One bad wire, on first light,will cause both to not work.on my bobtail, the others jumped from the first.

 

If you ck. above your brake pedal and look for another 2 wire switch that is on brake line that is leading to the emerg. brake buttons, from foot valve, some year models you must lay across floor and reach up under dash to get it out?
