I have a 96 Accord with the same light/flag. It usually starts to change colors (green=normal, yellow=attention, red=urgent) to remind you that the car needs to be serviced. To reset the light, there should be a little opening on your display (just below the speedometer) and all you have to do is stick your key into it to reset it, usually the mechanic will do it after you have it serviced. For more info, look in your owner's manual. Take it to Auto Zone for a free check up and then take it to any respected auto mechanic that specializes in Honda to have it repaired.
