Maintenance light 97 civic?

Recently my gas gauge stopped working so I ordered a 2000 Honda crv gauge cluster because I thought it looked better. This was about 3 days ago. I didn't notice this before but when I turn my headlights on, the maintenance required light turns on as well.

The light was never on before I changed the gauges. I'm thinking it could just be the illumination from the gauges lighting up that part. The car is mechanically sound.

Hold the odometer reset button in. Turn the ignition switch to on, DON"T START IT, in about 10 seconds the light should go off.
