Kahtec 3rd brake light Module
 

This module, causes the 3rd brake light to flash six times then go solid. My specific module is the smart stop delay, which means after the 3rd brake light flashes i've got an eight second period, where i can lift fully off the pedal before the light flashes again. (nice feature when in bumper to bumper traffic)

Now to the write up for the DIY,

Tools needed,
-pliers
-screwdriver
-3m double sided tape to mount
-scissors
-brain

When you order this somewhere around $32.00 shipped for me, you receive the module, a set of really pixelated instructions and three quick connects.

when you look at the wiring in the trunk well going to the third brake light you will see the circuit the black wire is your ground and the green is your power.

Take a quick connect and attach the red wire to the green wire on the left side of the circuit.

Then take a quick connect and attach the blue wire and the white with a green chaser to the right side of the circuit.

Take a quick connect and connect the black wire and the white with a black tracer wire to each other.

after you have done that cut the wire that is white with a green chaser on the right side of the circuit.

LOOK AT MY PICTURES BEFORE CUTTING OR CONNECTING ANYTHING

Attached photos of it installed and a video of it working

any pics or video of the 3rd brake light working?

Video should be working now.

nicely done! not my cup of coffee tho

Thanks! I purely bought this due to the fact i've been rear ended twice in a much bigger vehicle (lifted Toyota Tacoma) where the driver behind me flatout wasnt paying attention so i figure that this will draw some attention

Nice looking mod and I imagine useful to deter any more rear-ending and probably not a bad idea for track-goers as well. There was another DIY on here but with flashing rears instead of the brake strip. Personally I think the brake strips look nicer. I don't think the other mod had the smart stop delay either, which is a great addition. Do you happen to have a video with the rear taillights in the picture as well? Thanks for posting!

Tucker, nice list of "tools" needed...esp. the "brain" part! Haha. I also added some split loom tubing and couple of cable ties to make it look "factory" and prevent any wire snags when shoving something big in the trunk. The 3M double sided acrylic adhesive tape works well to attach the module. Thanks for posting this up. I've had several PM inquiries regarding "how to" and you've covered it all! Like you, I am very cautious regarding being rear ended as have had some close calls. The KAHTEC visual alert adds an extra measure of safety that might help prevent that one driver behind you texting on the road or not paying attention when there is a sudden slow down on the freeway....they say there are over 2 million rear end collisions per year. Next level of automotive technology beyond this to address the problem...they are adding sensors that automatically apply brakes. (Likely to be standard equipment on all cars in the near future.) Thanks again, man. :thumbsup:

Yeah, I'll be adding the tubing and stuff here shortly. I am ultimately going to solder the wires and give it a more clean factory fit and finish! Thanks for the advice John!

Ill see if i cant get one later tonight and will post it! I agree i think if you had the rears flashing i think it would be a little much and more confusing than anything to those who wouldnt know what theyre looking at.

Nice writeup and video, I have the same module waiting to install.

Planning to install it along with doing the foglight mod to 4th brakelight, but I will only have the module flash the 3rd brake light.

thanks for turning me onto this - i ordered one and installed it. works great. the only thing i did different was that i didn't use the quick connectors nor did i do any soldering. i actually took apart the pin connectors, and just attached the new wires directly (threaded them through the hole in the pin, and put the pin back into the plastic housing). they're held in there really snugly and there's no danger of them coming out. i also secured the wires with shrink wrap and electrical tape.

nice

This does not include the bulb for the 3rd brake light correct?

Correct, it's a small module that taps into the harness for the light. No need to touch the bulbs as its all in the wiring.

this is pretty damn awesome and I'm definitely leaning towards doing this, thanks...

is there anyway to make the flashes blink faster?

You could possibly talk to the company and see but the unit is sealed when you get it.

I wonder if you can do this to the rear fog light that has been custom installed...

nice write up...but it's kinda like F1 rear brake lights?

Yes, essentially but only when you hit the brakes.

I would think that you could do this to a fog light that's been installed. It's basic wiring.

I bought the kit but I accidentally bought the one for the main brake lights. The guide works but you just need to wire the blue wires together for it to work. Otherwise the third brake light wont blink

This is cool! :thanks:

Interesting
 

Subbed for possible order. Thanks!

Anyone know if this would work on the fog light (assuming that you have it modded to be a working light)?

I had the module, but got rear ended anyway LOL ! But since I was stopped for about 8 minutes before I got hit, the brake lights were solid for those minutes.

The module can be connected in various combo's (all brake lights, main only or 3rd only etc).

It is a good system for non led lights with nice bright seperate flashes.

I now use a strobe on my 4th brake light strip since it is led. On filament bulbs the strobe is hardly visible and the Kahle unit is more effective.

:cheers:

Bringing life to an old thread...

I bought and installed one of these http://www.kahtec.com for our Outback. Will be installing one of these in our BRZ this weekend.

With so many distracted, aggressive and inattentive drivers in my area, I think this device is just an additional measure to defensive driving.

I removed the OEM high mounted brake light from my BRZ and purchased an Intec high mount 3rd brake light from FT86 Speedfactory http://www.ft86speedfactory.com/inte...ight-2005.html. It is a bit pricy, but I hate the OEM unit from both a safety and astetic perspective.

On our Outback, rather than use the wire taps, I decided to solder the connections and cover with shrink tubing. I also used split loom to cover the wires to provide a finished look. Last, I used 3M double sided tape to attach the module to a panel. I'll do the same on the BRZ.

Wow this looks great

Remember folks, in Ontario a flashing brake light is illegal EXCEPT on a motorcycle.

Been flashin almost 4 years now, still waiting to be pulled over.

I think the speed tax collectors like the flash because - less rear enders, less down time for making more money (besides the lazy buggers hate the paperwork).;)

And yeah, the Toronto tax collectors on iron donkeys have the strobe led flashing brake light.
But they can't watch TV, work a computer, and use a microphone and cell phone like the cops in the cars.

Could you post a video of how it looks with the Intec light? I just installed mine and have been looking at this module as well. Thanks!

I plan on installing the Intec this weekend. If I can use Photobucket to post a video, I will. I've never actually posted a video before. :)

Haha okay. I haven't done any videos either :iono:. If it doesn't work no big deal!

Is this illegal in British Columbia?

Great thread! Just installed mine, works great. Definitely needed here in South Florida with all the older folks on the road and bad drivers down here.

How's this holding up 4 years later? I purchased one last year (different brand) and it's already not working.

Bump. I'm not sure what brand does a quick strobe like this, but I'd like to know. Seems like it would draw less attention but still let people know you are braking.

That's exactly what the one i had did - SUPER fast strobe effect. I'd actually prefer a slower one.

Plus, mine died within a year or so.
