High-performance tail light for cycling We are confident in our price and performance!!! It really stands out. The appeal is intense!!! It's seriously amazing. The LED lasers on both sides are clear lines They illuminate the road❗ You can choose from off → on → flashing. Compared to a tail light that just has one light in the middle, you can ensure safety to an incomparable degree. The flashing of the tail light in the middle has 7 patterns. The large lens provides excellent appeal. There are slow flashing to fast flashing, and you can easily change it depending on the situation. Easy to install on the saddle post. Uses 2 AAA batteries (sold separately). Because it's LED, it lasts a long time. We also have other great cycling items for sale. Thank you. #Affordable cycling items on sale
