While reading most the comments below about what lasts longer than expected , have you ever stoped and wonderd about the dinger in the cars ... .no one mentioned the SEAT BELT WARNING BUZZER BELL chime DINGER .they never fail the entire life of the vehicle ,and are nearly impossible to disable without breaking something critically necessary if they are rendered disabled ,,. . imho , one could go rite down the line in a junkyard turn the key and open the door, connect a jump box and I would bet 9 out of 10 would sound off ....the seat belt warning guys should build the ENTIRE CAR ,AND most everything else in this crazy world
