Re: Adding a 3rd Brake Light to a '67
What your missing here is the backfeed issue.
Reread my original posts.
I never said your way wouldn’t work.
What you failed to realize from the start was the flashing third brake lamp during hazards operation when you wire it your way with a stock switch.
To each his own, you can do what you want, but I stated the facts an am correct. If you want your third brake lamp to be compliant like a modern car, you simply can’t wire it like you stated. If you just want it to work in the most simple form, then yes, you can just splice into the factory wiring. Case closed .
