Nearly 2.5 weeks after I ordered online, my Kahtec Flashing Brake Light arrived. I ordered the Blinking Smart Stop, Delay Version.
Here's how it looks like after unpacking from box:
It comes with the flashing unit and three wire clips:
The unit is very light and small (smaller than a matchbox) but has rather long wires:
Now to install. My car is Nissan Grand Livina. This is the third brake light cover (standard):
Carefully, remove the cover:
It's unnecessary to remove the bulb but since I didn't have anyone immediately available to help me step on the brakes, I remove the bulb so I can see it flash when I am in front to step on the brakes. Find the bulb wires (blue + black):
Remove the wire tape to expose more the bulb wires, and make the connections, following the Kahtec wiring diagram, like so:
Connections were easy. Took me a minute or two only. Once done, tidy up the wires and tuck in the Kahtec box somewhere within the third brake light cover, like so:
Carefully place back the third brake light cover. Done! The whole operation took me about 30 minutes. I had slight trouble putting the cover back. I had to work slow because I didn't want break the cover hinges or something.
I am not putting up the video to demo the flashing brake light because it looks exactly the same as the other videos links I put up. Please refer to them if you are curious.
The third brake light flashes about 6 times in 2 seconds when the brakes are applied, then the light turns solid. If you press the brakes again within 8 seconds, the brake light does not flash (remains soild). But if you press the brake light 8 seconds or more after the last brake press, this would cause the brake light to flash again.
For people who want to DIY, there are a few electronic circuit diagrams on the net. Some are rather noisy because they use relays (can hear click-click whenever you step on the brakes), but I think Kahtec unit is nice and small, so I can put the unit inside the third brake light housing.
