Winking Brake Light

[RGuzz]

Faintly winking brake light in dash. The fluid levels seem to be okay 
no trouble from the bomb...yet. I do have the sense the problem is in 
the emergency brake handle. Going over bumps seems to affect it. I have 
replaced the IC because of many in dash gremlins, all gone, but this 
persists so it's not in the dash. How do I tackle the brake handle 
thing?
I know this has been discussed before.
Happy thanksgiving.
