Adding an integrated tail light is simply the best way to improve the looks of your bike, and when that integrated tail light is designed by TST, it gets even better. With a completely different look than your stock tail light, TST is here to help you set your bike apart from the rest of the crowd. We designed a tail light that is completely unique to anything else on the market, and by creating a custom design that aids in functionally and visibility, we strongly believe that we offer the best solution to cleaning up the tail section of your Kawasaki Z125. Mounting in the same location as the old stock light, our integrated tail light will add more visibility with brighter LEDs and a unique design. Our integrated tail light is designed, manufactured, and exclusively sold by TST Industries.

FLASH RATE: Installing aftermarket LED lights may make your signal flash rate speed up or cause your signals to stay on constantly. We highly recommend our LED Flasher Relay to solve this issue.

This customer purchased the item at our site.
I,m so glad i purchased the TST LED intergrated tail light for my 2018 Kawasaki Z125 pro! I was trying to install another brand LED rear blinkers with no luck at all. Quality fit, finish, function is top notch!! Well worth the money & the customer service at TST (Mark) is awesome! Thanks for making great products for my project bike.

Advantages: Video install takes all the guess work away making it easy. TST flasher relay makes front/rear blinkers work correctly.

Disadvantages: None

Long overdue review - purchased this taillight set about 24 months ago when I still had my Z125. Amazing quality - stunning options with the scrolling indicator setup and the quick flash and solid rear brake light. Never had issues apart from one dead brake LED after 12 months but I think that was more to do with a tiny bit of water/mud getting in there. Worked perfectly all the way up to the sale of the bike!

Advantages: Amazing looks really amplify the attitude of the bike and smoked look blends the light into the black plastics of the bike when it's off.
Plenty of options for how you want your taillight and indicators to display.
Great looks and very high quality.
No fitment issues - straight bolt in.

Disadvantages: 1 LED died but it could have been due to unusual use of the bike.
