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

I haven’t had this on my bike for long but the taillight must not have been sealed off very well as I already have moisture inside my taillight. The led lights have stopped working on one side of the brake light. I would not purchase this again or any other TST Industries products in the future. Very disappointing!!!

We contacted this customer to request photos of the claim and were able to verify the tail light needed to be replaced. However, they refused our warranty replacement and was issued a full refund.

I love the TST Ninja 400 integrated tail light, and fender eliminator. Very Clean, Very easy to install. We installed it as soon as it was delivered, like kids on Christmas. High quality as always. It inspired us to update our Ninja 300, and bought the Ninja 300 tail light.

Advantages: Nice clean lines. Exact fit. Easy install. Very bright. Great programmable light options. Easy to convert back to stock any time, not that any one would.

Disadvantages: none.

These taillights are amazing! Couldn't be happier with this purchase. Installation was a breeze thanks to the video provided in the product page.

Advantages: Brighter visibility even during sunny afternoons. Provides driver alert with the different modes for stop light and turn signals. Enhances the look of the bike.

Disadvantages: Causes envy from fellow motorcyclists that haven't bought the product yet.

Absolutely beautiful and well built taillight. I hated the stock bulbs and wanted something clean. All I am going to say is... WOW! Freakin' amazing OEM fitment and beautiful bright LED lights. The sequences are a huge bonus. I can switch my brake/blinker combos in less than 10 seconds under the rear seat. These guys put a lot off thought into this design. At the time of purchase, smoked option was sold out..to be honest...the clear taillight I received is so sharp and it completes the look of my 400. Do NOT think twice. Chuck up the $. You will be hyped.

Advantages: Tight and juicy OEM fitment with multiple light sequences.
BRIGHT - I feel safer during my morning commute. Never trust a sleepy cager!

Disadvantages: Find one.

5 Stars. Out of all of the "fender eliminator" options I could find, TST had the best looking choice hands down. Complete with install video so you can't go wrong.

Smoked out LED tail light with Integrated Turn signals with multiple flashing modes? Sold.

Is the ACTUAL fender eliminator, Relay for the Hyperflash and plate light sold separately? Sure but the price of the combo is around the same as any other option but with a much nicer finished look.

This is the must have Ninja 400 fender elim Kit hands down.

Wow what can say that hasn't been said about this tail light, fit perfectly super bright, change the over all look of the bike in a few short hours.

Advantages: Very bright, programmable, and perfect fit

Disadvantages: None

bought a used bike with the smoke TST, it seemed to have a factory defect or maybe it had water get into it but it wasn’t working properly. I really liked the design and the programming options so i went ahead and got the clear set. took a few hours to take out the old one and put in the new but so far it looks great and is pretty bright.

Advantages: Different settings for brake light and turn signals, TST company responds very quickly to customer concerns

Disadvantages: none yet so far!

Gave my bike a beautiful rear end and got rid of the ugly tree!

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.
