## Questions & Answers

**Q: How do you know when it's done charging?**
A: First, the charge lasts a long time.  When you plug it in to charge, there is a little red light.  One of two things happens - either the red light goes blank and is no longer lit - or it goes green.  I have enough of these gizmos, I just don't remember.  I use it on my helmet.  Good luck.

**Q: Are the lithium batteries replaceable?**
A: We don't recomend customers no professional replace the built-in battery. If the light is used carefully, it will last for years.

**Q: How do you install?**
A: The installation is easy with the rubber band in the package. You can check the product page to see details.

**Q: 220mah battery - is this a joke?**
A: I have had the light for about 2 years.  I use the rapid flash sequence.  If I ride daily for 2-3 hours, I charge the light perhaps every 4-6 weeks.  I'm quite pleased with the light and the battery life.  I have not seen the battery so I cannot address the specifics on the battery.  The light works great.  That should be enough.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Best rear light, survived a collision with no damage!
*by D***N on January 14, 2025*

This light is bright and strong. It has multiple light options and is easily rechargeable. The light survived being rear ended by an e-bike at high speed. My heavy aluminum bontrager rear rack that it was mounted to bent inwards but the light had no damage. I highly recommend!

### ⭐⭐⭐⭐⭐ I Love This Light. Great for Safety. Quality Design.
*by C***Y on October 21, 2020*

This light is awesome. Great safety for riding at light, or even in the day for extra visibility. Long battery life. Love the Tai Chi mode where the light spins around. Easy operation (it remembers the pattern you set after turning off). Easy mounting. This is the best.

### ⭐⭐⭐⭐ Shine your light
*by C***N on June 23, 2025*

Awesome rear light, tremendous visibility and runtime. Good investment.
