The light on the DSC should mimic what your signal light does (they're connected internally). Remember to jump the signal light so it's configured for solid light operation, even though the operation is rarely actually solid.

Here are the blink rates, they depend on what mode your robot is in:
Solid ON - Autonomous enabled
Solid ON but blinks off every 1.5 sec - Teleop enabled
Slow blink (900ms ON / 900ms OFF) - System disabled by system watchdog, user watchdog, or driver station set to disabled
Fast-slow (200ms ON / 900ms OFF) - Low battery (<12V) or no user code AND system disabled either by system watchdog, user watchdog, or Driver Station set to disabled.
Fast (200ms ON / 200ms OFF) - System error; no Driver station communication; bad cRIO image, bad team ID, extensive communication errors
