TST Programmable and Sequential LED Integrated Tail Light for Kawasaki Ninja 400 2018-2023 / Z400 2019-2023

Looks great on the bike and eliminates the incandescent turn signals. It was a bit tricky to install, and I wish kawasaki hadn't done some of the interlocking tabs they did. The video was great for walking through the process

Advantages: Looks great and functions great
I like the 3 flash on braking

Disadvantages: TST uses blue wire for power and yellow for brake signal. If you want to tap into the brake signal for an LED lighting mod that can turn red on braking, keep this in mind.

Overall, this is a very nice taillight. For someone who's going to remove the stock taillight, signals, and fender, this is a great integrated replacement. It's high quality, it has a built-in flasher for extra visibility, and it's all plug 'n' play. If this became the default choice for people ripping out all the stock stuff (compared to cheap taillights with a handful of LEDs and tiny little turn signals), I'd be overjoyed. Since the stocker only has 10 LEDs in it, I think TST's LED array is actually better at covering a large area.

I love the sleek look of the smoke lens on a black bike, but ended up going with clear to avoid any reduction in output and to match the rest of the lenses on the bike.


As a picky geek, I have a few small issues with it. Most people won't care about these things.

The plugs/wires don't match OEM colors. For most people, this means having to swap the turn signal plugs at worst. For additional mods or troubleshooting, it does make things more confusing though. It would be better if they used the same colors as Kawasaki just to make things a little easier, but it doesn't affect operation of the light.

The flasher has very limited options compared to the separate flasher I installed on my previous bike. That one is configurable in how fast it flashes, how many times it flashes before going solid, and how long of a delay is needed before the flasher resets (so it's not flashing every time you let off the brake in traffic).

The signals are pretty large and well-defined for an integrated unit, but they're still a bit small for sequential operation. They simply lack the area of a car's taillight for the motion to be fully realized. They also seem to bleed a bit of amber into the other sections of the lens. I am rather impressed with how large they made the signals without impacting the brakelight area too much.

My fender eliminator retains the stock turn signals, which I'm keeping for better visibility. I'll be using my external brake flasher with more options once I get the proper connectors for it. In the end, I'm just using this as a plain brake light with a clear lens. If TST offered a cheaper version without the flasher and integrated signals, I would personally be just as happy with that one.

Advantages: High-quality build.
PnP install.
Large, bright LED array.
Built-in flasher.
Relatively large signals.

Disadvantages: Plug/wire colors don't match OEM.
Flasher has limited options.
Signals are a bit small for sequential action.
