Yesterday I popped out one of the blanks to see if my Scion switches would fit.
Scion OEM Style LED Rocker Switch
The switches are indeed too big to fit without some modification to the truck. The switches fit in other Toyotas so I thought they might fit in ours. They are too tall and would require some grinding on the mounting plate to make them fit. I'm just not positive I am set on this switch for my lights. They have a loud click when they are switched and do not sit flush. I'll see if I can find a better alternative.
