Not the ABS light but the Brake light laminated on the dash all the time. Brake reservoir has the proper level of fluid and I even replaced that sensor at the bottom of the reservoir. Would bad wheel sensors on the hubs cause this light? The ermgency brake level/switch works fine and I don't think it is triggering the light. I don't have a valid ABS light, it doesn't light up when starting the car so I guess the previous owner disabled the lights.
