Review on 🚴 Nite Ize TwistLit LED Bicycle Light: Versatile Attachment, Bike Safety, 2 Pack - Red & White LEDs by Jerry Forehand

I bought these for my kids for bikes a few years ago and when they got on I put them on dog harnesses for an evening. They work great. The neighbor even joked that because white has a green tint, they look like port and starboard. Eventually one fell off (was in there for at least 3 years) and I lost the other while washing the dishes. Happy to find new ones. VERY bright and I already know they will last. It is very easy to change the batteries at the right time. Very helpful and highly recommended.
