If the 4 arrows do not illuminate does the entire switch require replacement or can it be repaired to restore that functionality?
The same switch is used in all 360s and the 575M so maybe someone will chime in with an answer. You might be able to open the switch up once removed to see if the bulb is replaceable.

The L and R do not illuminate. They are just silk screened from the factory. When we refinish them, we laser etch the L & R. I actually did not think the arrows illuminated, I just thought it was a glow in the dark type material. http://youtu.be/JerZHMR8jn4
