some what imbarrased with this question how do you turn the park light on a five ton

I can get the flashers on but don't know how to put the park lights on, help, thanks, Joe

If your truck has this switch you need to have this combo of levers: headlights on and then second handle set to park. If you have the pushbutton keypad switch I have no idea...

Are you trying to get the park lights to come with the head lights, or are they just not coming on at all? Check the bulbs to make sure they are not burned out. The park lights and head lights don't turn on at the same time unless you use a jumper wire. Erik's Military Surplus used to sell a jumper wire that connected in place of the wiring harness which allowed the head lights and park lights to come at the same time.

Probably be a good idea to read this :
TM9-2320-272-10.pdf
TM9-2320-272-10 Operations manual for the M939 series trucks. Sept 2004

[h=1]TM's for the 939 series trucks[/h]

Thanks guys, guess I should learn to read, heck at my age its to late, I wanted to use the park light only have a parade for the local High school ROTC and just want the park lights on in the parade, you all are so helpful, will read that in operations manual, thanks again, Joe
