I also plan on adding the third light, but his picture troubled me. The actual brake lights look dim. I been looking at installing these in my cars. This style of LED brake lights are much brighter, get 30,000 hours and fit into the fixture that is already there without any modification.

I tried LED bulbs and was disappointed. You can also use 2357 bulbs instead of 1157; the 2357 is the same bulb but with a much brighter brake element. Get the long life version. Some also say to paint the inside of the lamp housing flat or semigloss white to make even brighter but I have not done that.

Doing the spring clean-up, thought illustrating the method would be useful to others - this basically makes the 3rd brake light a "separable" task without too many contingencies on clean surfaces, etc. We attached the lights to some vinyl weatherstripping, and then attached that to the upper screw positions in the rain tray. Basic idea:

Looks like this from back (lights off):

Looks good! That stretch of roadway looks like Baron Cameron Parkway near Lake Anne Center in Reston, VA.

I'm not sure why that would be the case. Modern cars like Volvo which use the bulb I linked too, have super bright tail lights.

^^ I'm sure it depends on the particular LED bulb you are using. I tried 36 LED from superbritelights and found the LED to be a little brighter but less full in running light mode, but much dimmer than the std 1157 in brake light mode, which is where you want the lamp to be brighter. The 2357 on the other hand is way brighter as a brake light.

on 60-69 cars its common for average 1157 bulbs to melt the red plastic lens. I would be hesitant to use a hotter standard bulb, are they hotter? Id experiment with some LEDs that projected the light towards the rear. Lots here.

To clarify...

The third brake light is very bright. It is the same or greater intensity (because of the overlap) as the surrounding newer vehicles. As we tried to say in the original post, the KG tail light brightness is dim, because at the time, the running lights and the brake light connections were wired wrong and were reversed. No one working on her in the past had caught the mistake. (She had passed inspection last year but this problem was brought to our attention when they failed her earlier this year.) We have since rewired the tail lights properly and have appropriately "brighter" brake lights and passed inspection again. It had always troubled us to have such dim brake lights, so the third brake light was a priority. Now, we know why those tail lights were so dim. I still feel that the third brake light is the one that people notice most though.

My concern now is that at night the running lights will be dim, and I will not be seen as easily as when they were wired for the brake light filament intensity. We tend to not drive her much at night, but it will always be on my mind whenever we do get caught on the road after dark.

In the past, we, too, tried LED replacement bulbs, but they didn't work for us.

Yes, it is that intersection last Fall before all the salt. You know NOVA roadways well to pick that out.

I used to live in Reston a few miles from there. I guess I traveled that stretch far too many times - LOL!

Thought I'd post some photos of 3d led brake light and 2357 bulbs with direct evening sun on car, since these are the conditions we need to stand out in. First photo no lights on...

The 2357 bulbs are very bright and very red, which doesn't come through in this photo. As for melting the lens, mine are staying relatively cool. Cant speak for the earlier lens, but with the '70/'71 lens there is at least a 1-inch space between bulb and lens to dissipate heat.

I found this stop light -

I haven't sized it up with the ghia - I'm hoping it'll fit nicely on the parcel shelf in the back but we'll see... it's pretty cool anyway. This thread has some great ideas if it doesn't work out.

Very cool!

It almost has a similar profile to the Karmann Ghia side emblem:

It would be cool if you could find some printable material that is transparent when lighted from behind and use it to make a copy of the Karmann Ghia side emblen to fit over the lens of your new stop light.
That way it would look like a large Ghia badge, and the "STOP" would shine through when you touched the brake pedal.

Nice install ideas. Cool
I decided to try a different route especially since our Ghia's are a bit low I wanted to get a third light into a drivers field of view. I found a billet light from Watson Streetworks

I mounted it in the top of the back window with a plug and Velcro. I can remove at a show but I have rarely done so.

How are all you early Ghia owners getting these into the solid steel rain trays?
I cannot figure out how to get them into my '69 Vert.
Thanks.

I tried the double sided tape that came with a led strip in my engine compartment. It got too hot, the tap fell off, and the led strip got slightly abraded by my fan.
