What does this button do?
What is not mentioned in the manual is the mirror spot lights also turn on with the bed lights. And those are the LEDs pointing down, not the 'spot' LEDs on the side of the mirror, which are turned on with the switches above the light switch panel. But yes, the bed light switch should have an ON light, like the spot ones have, but not a huge deal since they turn off at speed.
I also posted the 2018 manual, same switches in cab and bed. See post #12 in this thread. That is the 2018 manual. Same info.
The OP is asking about the button in the cab located beside the headlight switch, which is why I circled it in red. Not sure how more clear it can be.
