[Supras] Help with Brake Light Failure

[JAMES]

   When I start my 89t and tap the brake pedal the "REAR LIGHT FAILURE" light comes on. 
 I checked the brake lights and they were not working. I replaced the bulbs and cleaned the
sockets. They worked for about a day, the light came on and they were out again. I replaced
 the bulbs again and checked the fuse and I still can not get them to work. The taillights still
 work but not the brake lights.The brake light on the spoiler still works. Any suggestions would 
be appreciated.
