Nite Ize TwistLit LED Bike Light
With a quick turn of the wrist, the versatile, visible Nite Ize TwistLit attaches to anything on wheels, making it easy to spot in every kind of light. Featuring a long-lasting LED module encased in specially formed housings, the TwistLit is designed with a curved back that rests snugly against the round surfaces on your bike or scooter. Grooves on each side hold sturdy, flexible rubber Gear Ties in place - with ends to wrap through, over, around, or under the front and rear of bicycle handle bars, seat posts or racks of nearly any size. Twist closed, and you're done.
Have been using this product for 2 years and its lighting performance is marginal at best. Definitely a "Be Seen" type of front light, not a "To See" so potential buyers should be aware of that. Doesn't emit a strong beam that will illuminate the road ahead. Battery consumption is below average, as a fresh CR2032 only lasted for about 2 months with a 2x/week use @ 2 hours run time. Barely recommends this product.
