3rd brake light

[bluef250]

Has anyone installed a cargo light with a third brake light instead of the stock cargo light?

That's a good idea. I have thought about that too. Probably tap into the existing wiring for the brakes and run it up to the light. I don't know if a red bulb would work, or if you'd have to get the clear lenses tinted somehow. Maybe a red LED type bulb would work?

I've also wondered how hard it would be to modify one to be a cargo and a 3rd brake light. A second light socket would need to be installed. Probably more trouble than its worth. I would think your idea wouldn't be that hard.

My 67 didnt come with the cargo light. I bought a 3rd brake light kit from Sir Micheals I think. It came with a template and looks real easy to install. Just run one wire to the brake light harness, either side it doesnt matter or as I did, tapped off the brake light switch at the pedal. I'll see if I can dig up the photo and instructions. Been a long time.

The only problem would be that adding a second setup would put it off to one side or the other. I've contemplated this as well, and decided that the only way of making it look good would be to add TWO more, one to each side of the original, essentially for two extra brake lights....if you were to wire them right, you could get your turn signals working side-to-side up there too!

...but like you say, probably more trouble than it's worth. I'd like to install a third brake light, but I'll probably use one from a junkyard. I'll just have to make a template of the roof curvature to take with me, for finding one that will set right on the Ford roof.

be cautious where you tap into your brake light wires. A friend of mine added a new wing to his mustang w/ a 3rd brake light. the car never had one before. He tapped in next to the rear light housing on left side. Now when he puts on his brakes it lights up beautifully.........but when he hits the left blinker it flashes...lmao it looks a little funny.

I think, the electrical tap for the brake needs to be made before the turn signal switch, perhaps right after the switch on the brake pedal to avoid the left / right turn problem.

exactly right then run a wire from there through the cab and up to the 3rd light. I dont see any other way to avoid a new blinker.
