switch

Hey guys! So I recently realized that the back-light bulbs in a couple of my Toyota OEM switches had burned out! Specifically the back-light for one of my aux light switches and for my A-TRAC switch. So here is a write up showing how to replace those bulbs. First, here is the "before" photo...

I have a strange switch on the left side of the steering wheel next to the clutch start switch. Below is the picture when I flip the switch, the following icons light up on my dash. could anyone tell me exactly why it does this?
