Rear cab work lights

If they're like my 16.. you can only turn them ON at a stop.
When you reach about 5-8mph they turn OFF automatically.
BUT...
If it's like mine.. because I put amber LEDs in mine bc it's purdy.. once they turn off, just flip the switch OFF/ON again(while moving) and it will illuminate in motion.
Then you can check it anytime while you're going down the highway u til you turn off the ignition to kill the sequence.

 

U guys know what's the fuse number... I found the fuse box but have no idea which is the fuse for the cab work lights

 

Xirtam2k the work or utility lights might be over current protected by the SAMCAB and not have a fuse. Look at the SAM wall chart in this link https://www.dtnaecomponents.com/Fre...DateAugust2nd2010AndNewer/SAMWallChart6_0.pdf
I see utility light output at connector X3 pin 7. (X3/7) which is a logic controlled output that is unfused but will turn off in case of over current. The utility light ground looks to be on connector X3 pin 21.
