The pulse module we use blinks every time you use the brakes. It doesn't stay blinking. It only does it 5 times then stops. I haven't heard of one that you have to wait 8 seconds or so for it to blink again when pressing the brake. It could just possibly be a bad module but from what we use at work, it goes off every time

This morning on the way to work, I pushed the brake and it would flash then go solid, If I hit the brakes right away after letting off them it would not flash, just stayed solid. If I waited a little longer it would flash again. I will have to time it to see how long before flashing again. I can also get some pictures of the module if people would like. It had some writing on it. Its only three wire hookup. Looks to be in series with the positive, and grounded to the negative. Looks to be a simple charge-discharge timer circuit.

I installed one of these on our BRZ and our Outback. On the Outback, the 3rd brake light blinks 5 times each time you apply the brakes. If you stay on the brake the light remains solid.

On the BRZ, the 3rd brake light blinks 5 times, remains solid, but will only blink again if 8 seconds elapse between brake application.

Because the BRZ is so low, I felt I needed something to alert distracted drivers. I also installed an Intec high mount 3rd brake light.

Kahtec offers several types of flashing modules. Installs in minutes and can easily be uninstalled.

Which one did you get?:http://www.kahtec.com/US_Order_Form.htm

I'm very interested in buying one, I've been getting alot of people that ride right up onto the tailgate under light braking to a stop or won't see the car. I'm guessing you got the Blinking Smart Stop Delay?

Multiple cars are now coming with them form the factory. There is a bunch of peer reviewed academic literature on their effectiveness in reducing the number of rear end collisions. They are expected to be mandatory, just as daytime running lights are now mandatory, on all new vehicles. They need to pulse, not flash to be legal. So on/brighter/on, not on/off/on.

[Poodles]

The original intent was to have them flash at a rate that was based off how hard you were braking (I think F1 cars have this)


I have it in my Valenti 4th brake light. Haven't had many people come even close to hitting me because of it though.

Those are about as annoying as Harley rider's flashing headlights.

Installed a similar setup but with a cheap $50 mustang high mount light yesterday. [ame="https://www.youtube.com/watch?v=7QdpBxfboEk"]kahtec standard + mustang high mount brake light - YouTube[/ame]

I got the annoying one with no delay (so it always flashes six times then solid). Figured I coast most of my way in a low gear that I barely brake but I've seen too mnay people run up close to me a few times that this brake light was installed just for them

[ARTBRZ]

I need one of these. Maybe I can annoy those people who tailgate me. But I think I'll need the one that doesn't turn off.

On our BRZ we have the Blinking Smart Stop Delay.

On our Outback we have the Blinking Smart Stop Standard.

Thank you! The one that you have for the BRZ is what exactly I'm looking for.

I've been noticing a worrying trend of people riding right up on my rear end when I'm stopping. I've been employing my own version of this...I just push and release the brake pedal a few times when I see someone obviously not slowing down. This might be a better solution.

Do you do any cutting of the wire harness?

+1 Hows the install? Do you have to splice into the third brake light harness with like t tap connectors?

Yes, although I wouldn't call it a harness. You must clip a single wire. Take a look at this link http://www.kahtec.com/install_smart_stop.htm . You'll find the instructions here.

I did not have to clip the OEM wires. Since I removed the OEM 3rd brake light, I just took the connector off that, and soldered the Kahtec module to that connector.
