Safety Indicator Sensor
 

I have a 1993 Honda Accord LX 4 door sedan. All of the safety indicator lights on the dash that show if a door is open or a tail light is out are on and will not go off. They flicker occasionally and may go off for a few seconds but come back on again. I think there is a sensor located in the rear axle area that may be bad but I am not sure where it is located. Has anyone else had this problem, how did you fix it, if the sensor needs to be replaced please advise location and part number. Thank You. Sabre

May be the alternator failing or the brake switch.
