red light

This may be a silly question....but I just purchased a 97 Isuzu Rodeo and in the upper left hand corner of the dash where the rear hatch release switch is located....there is a small red LED next to it.....this light has never come on.....would anyone know what this light is for????

Thanks for your input....

alarm. you if your truck didn't come with a keyless entry fob i would bet you could but a used on off of ebay, reset program it and you have keyless entry and alarm on off.
