Re: Adding a 3rd Brake Light to a '67
I never heard of the turn signal isolator until now. I was about to buy it on ebay but I looked at the reviews on Amazon. Like 90% complaints, it's junk, it fried, it doesn't work...
Did you wire it directly to the brake light switch, then?
I would at least upgrade to a Led bulb in that G body housing. I did that on my daughters car and it made quite a difference in brightness and how fast the 3rd brake light goes from zero to full illumination.
You could upgrade to a led strip light, as long as it would fit inside the unit, not sure it would be worth all the trouble?
The bulb would be a lot easier and cheaper. Does it take an 1156 version LED bulb?
