Actually I think you and Kaleb are right. I thought the FASTEN BELTS light was working properly but I just checked and it it not.
The BRAKE light works with the parking brake as it should. The brake wear light, which looks like (O), comes on momentarily when the key is first turned on. The FASTEN BELTS light does not come on at all, unless I step moderately hard on the brakes. So my guess is -- a prior owner has switched the bulb holders, and possibly also bypassed the seat belt switch.
