What are these toggle switches for?

My dash is just like that, but doesn't have the toggle switches. Looks like somebody put an aftermarket accessory on there like lights or a fan or something at one time.

 

One for chicken lights. Other for super trucker mode.

 

It's the fun switch.

 

Probably a Jake brake that doesn't Jake no mo.

 

They activate the blinker fluid.

 

That is probably the cruise control, one is on and off and the other is set speed, on and engine RPM setting at the top.

Sometimes there is a toggle pair for the Jacobs braking as well.

Sometimes he whole dash is toggles. It depends on how old it is.

 

due to the fact that they don't match the other switches and they are not installed level to each other id say they are not factory someone added them witch means no one here can tell you what they do, you can try turning them on and see what they do. hopefully neither is a ejector seat

 

1) incognito switch (turns take lights off)
2) ejector seat

#1 is a possibility.

We used to do that so when we got shot down with radar our brake lights didn't tell on us for having a bird dog.

 

Could be activation of 2nd and 3rd turbo when going uphill !
