Wow, just trying to help those cure their problem temporarily, never thought it'd generate all this.
If this were a classic or something, I guess I'd feel the same way. But a $70 or more switch not counting the special tools required is a lot.
In my case, the turn signals are working fine. My main brake lights were not. I can see when my turn signals aren't working by watching the blinker, but I can't see that my brake lights weren't working. After almost getting rear-ended a couple times, I knew I needed to fix the brake light problem.
As far as the third brake light "blinking", it's impossible. The third brake light is wired directly to the brake light switch, the main lights are wired through the turn signal switch. As for overheating the wiring, the third brake light had 16 gauge wire going to it, virtually the same as that going to the regular brake lights. If it were going to overheat, they wouldn't have used it for the regular brake lights. The car that I removed the pigtails from had 3 lights wired using the same gauge wire. I don't see that as a problem what so ever. But, it is a cause to consider ... I'll keep an eye on it.
