CatEye Rapid X Tail Light

The Rapid X is a USB Rechargeable rear light that attaches to the seat post made with proven Cateye quality. It provides a bright, powerful glow with incredible side visibility. When the battery runs low, the low battery auto save function automatically changes the light pattern from the current mode to flashing, providing an additional hour of riding safety.

This sleek rear safety light has 6 modes and a 2 hour charge time. Run times are 1 hour on high, 5 hours on low, 8 hours on vibration, 16 hours on pulse and rapid and a whopping 30 hours on flashing. A rubber band mount makes installation a tool-free snap and allows the Rapid X to fit 12-32mm diameter seat posts.


  • USB rechargeable
  • Very light at only 22.5 grams
  • 6 different lighting modes
  • All weather
  • Mounts to virtually any seat post shape

Love the light, but only good for the life of the weakest link, the rubber band that fixes it to seat tube!

Pros excellent light, rechareable, light weight

Cons should come with multiple rubber bands, not 1

Bright, rechargeable, and fits my slightly aero seatpost. I use the pulse light mode the most. I charge it once a week even if it doesnt need it. My nightly commutes are only 20 minutes so I havent test the run times.

Pros Bright and many modes to choose from

Cons The price if it isnt durable in the long run
