What does the TICS light on a Honda car mean?

I have a Honda and never seen a TICS light on it (or any previous Honda I have had), perhaps you meant TCS light (which my current Honda and the 2 previous ones have).

The TCS light is the Traction Control System light and comes one when the computer detects that the wheels are losing traction on ice or snow, The wheel(s) that have lost traction are drive wheels that suddenly spin much faster than their opposite partner(s). To correct this the computer briefly automatically applies the brake on just this wheel(s) then releases the brake to see if traction is restored. The TCS light is on during each of these braking events.

This is an automatic system and should be allowed to do what it needs to do (i.e. do not brake yourself, which may trigger a skid) however if the light persists ease up on the gas a little to reduce the chance of losing traction on the ice and snow.

This is all explained in the user's manual. Traction Control Systems have become common on many makes of cars, not just Hondas.
