Review on 🚴 BikeSpark G2-20lm Auto-Sensing Rear Light - Super Bright LED Bike Tail Light with Motion Sensing Deceleration Flash - USB Rechargeable - Water Resistant IPX5 - Made in Taiwan by Daniel Jenkins

Really good brake light, I particularly liked the automatic on/off and the light pattern that changed as I slowed down. The only reason I'm not giving it 5 stars is because the mount is terrible. There's nothing quite like going on a long journey and realizing halfway through that your taillight is gone. The elastic was still wrapped around my seatpost, but the attachment system was completely gone. I am happy to report that I have contacted the seller to express my disappointment with the mounting system and they have supplied a new replacement bulb.
