Maybe a flashing Strobe Light? Or a camera flash? (IMG:style_emoticons/default/av-943.gif)

Here's the link from a few years ago discussing 3rd brake light options. And yes, I put a blinker relay in the hot lead. What I thought was interesting was that when I videotaped the light going on, you can see it light up (LED) a few milliseconds before the incandescent tail light bulbs:

There are all sorts of cheap options for a LED 3rd brake light on ebay/aliexpress that flashes at first and all that.

I'm thinking the same from these folks.

I'd prefer if Spoke @Spoke can offer a group buy. Keep the $$$ for our valued vendors.

I totally agree with the importance of the 3rd brake light. If you don't have one you should be thinking about mounting one. Some guys have mounted the 3rd brake on the engine lid which is fine but I prefer to have the 3rd brake light as high as possible on the vehicle since the 914 sits so low.

I've thought about doing something for the 3rd brake on the 914 but the issue is there is no existing fixture to be reused or repurposed. As well there are many off-the-shelf options for 3rd brake and LED fixtures and strips.

Any solution will involve cutting, drilling, or taping and that's something I've stayed away from with my LED boards.

About the front-end flashers when you hit the brakes, there are many standalone brake light flashers on the market; some for as little as $5.

One thing I have thought about making is a pigtail with or without a flashing module that would help to wire a third brake light onto the roll hoop or engine lid. This is what I did with my 914.

On my 914 I stole power from the driver side rear light bucket using a Y-spade connector.

For ground I used a ring terminal and attached it to the ground stud behind the relay board.

I ran the power and ground wires up the sail panel under the trim and over to the 3rd brake light.

The unit I used was from Summit Racing in the 12in version. They also have 9 and 6.5in versions.

Brake LED Strip

Using a small angle clip I mounted the light to the chrome trim on the roll hoop.

Attached Image

The LED is only 0.625 inches tall and is not seen from the interior because of the roll hoop pad in the interior.

Attached Image

I did have to file a little bit of the chrome strip for the angles to mount.

Attached Image

Also had to make a wire chase by grinding a slot in the roll hoop but this will be covered by the chrome strip.

Attached Image

It's a pretty easy install once the LED and wiring was determined. One thing I like about the wiring is none of the 914 OEM wiring was cut or spliced. One could also add a 3rd brake flasher in the wiring.

Lots of clean installs but the one I liked best if I remember it correctly was done into the chrome strip. It was a very slick install.

What would be cool but doubt the tech exists but a wireless light with magnetic base that could be sent a signal from the brake light switch to turn on..

IF there was, how many of us would forget to change the batteries?

True but we all remember to charge our phones.. Just a thought as no drilling would be required.
