DASH LIGHTS on 1996 GMC Jimmy

What is the green light on right side of instrument panel that looks like a headlight? No lights on exterior are out.

That green light is a reminder the daytime running lights are on. That light should go out when you turn on the headlights or apply the parking brake.
Thank you.
I must have a short because in 18 months this light has not been on and daytime lights have been on.
