• Wireless control panel
• Built in rechargeable battery (usb chargeable)
• Turn Signals
• Super bright LED light
• Lasers for even more visibility
• Works awesome

Please note there is a power switch on the side of the light and you need to hold the power bottom for a few seconds to turn it on. The remote can only put the light in standby mode. 

This is the ultimate rear light. Very bright and attention getting.

When I first tried one I was afraid it would be gimmicky and Chinese like.  I was pleasantly surprised. This rear light is awesome and adds to your safety a lot when riding at night.

If you like the idea of turn signals on your electric bike, this device does the trick in a very clean elegant package. 

Note: This only has mount for directly to the seatpost. If you want bolts for mounting to seat you'll need to buy them at hardware store.
