light is out of ballast switch

[mk_deuce]

is there a bulb in there that can go bad? My other two light up. When I run it either way I can hear the pump working, it just doesnt light up red.

I had the same problem. With mine the common wire came disconnected on the back of the switch. Just unmount the switch and rehook the wire.

Had the same issue. Jumped under the dash and found a spade connection loose. Put that back on snug and the light came back on. I'd be surprised if the light buld itself was burnt out. But I am sure there's an easy replacement buld for those - if not an entirely new switch.
