Installed these on my 2020 Z900, super bright and OEM quality. Super easy install with the kawasaki plug and play kit. These look so sexy compared to the factory Air Plane Wings signals. Super worth it and should have bought sooner.

Advantages: Quality, price, visibility, looks and installation

Disadvantages: If you put your eyeball right up to it when testing it will blind you. It's like a Star Wars gun that's a turn signal. Don't put your eyeball up to it, it's bright!

This relay was easy to install in my 2016 GSX-S1000F and functioned just as advertised. I have only used it for a day, but so far so good. Thanks.

Really good construction quality

Advantages: Easy to Install

Disadvantages: None

Awsome looking turn signals! Are very bright. I just love them.

Definitely a professional and fast delivering company. Customer service helped me in the past with the rear integrated lights and I really appreciate their business.

Advantages: Really bright!

Disadvantages: The only thing I'd say is not TST's fault but if you don't use electrical tape on the male and female connector you will short circuit the 10A Fuze on an mt-09.

I just installed this modulator to my m109r. It was a replacement for a previous modulator from another company. The previous modulator was clumsy to install and awkward to mount, but the TST was night and day better. Easy, intuitive, and adjustable. It could even be easily mounted to be accessible without removing the back fairing, albeit I doubt I would ever need to adjust it anymore. Probably the easiest electrical install I've ever done on my bike. I recommend it as the go to option.

Advantages: Very easy install
Intuitive features
Functional and adjustable

Disadvantages: None, works as intended

Had a slow speed parking lot accident with someone who blew a stop sign. The bike went down on my left side and the sliders took the hit. Protected the whole left side. Miraculously no other damage was done besides a scuff on the left mirror.

Advantages: Very good protection. Saved me at least $1500+ in damage.

Disadvantages: Replacements are out of stock at the moment. (Not TST's fault)

I can't overemphasize what a difference this makes to the look of the tail. Combined with the high mount license plate holder with LED light, the whole rear section looks ten times better than stock. Bart and the team have done an exceptional job making these items look oem. Installation was a breeze and I love the fact that you don't need to cut/splice/solder or tap any wires. Truly plug 'n play.

Advantages: Great aesthetics, extremely bright LED, great visibility of indicators even from 90 degrees. Everything fits perfectly.

Disadvantages: None.

I was one of the few whose holes in the block-off plate did not match up with the holes in the subframe. No big deal, there is an easy to follow video towards the bottom of the product page explaining how to loosen the tray and slide it into position so that everything lines up correctly. The finished product is very clean and I highly recommend it.

Advantages: CNC aluminum is used for the brackets, pivots and block off plates. I just know other companies would have cheaped out and used plastic. This bike is too good to cut corners, so do yourself a favor and buy the top quality gear which only TST can offer.
They even added texture to the face of the block-off plate to match the surrounding plastics. It's this attention to detail that sets TST apart.

Disadvantages: You may need to adjust the alignment of your rear tray on the subframe, but this is no big deal and only adds a few minutes to the job.

Overall - as is typical with TST this is a great product. I do have one complaint though...In the installation video Bart says to use the 12mm Allen bit until it "bottoms out" however - I believe that even when bottomed - the unit does not sit flush to the case. This is a critical detail that would have prevented me from stripping the plastic female hex receptacle. Just a warning for other users- I was still able to use my unit - so no harm no foul here - just a note of detail here.
