Comments about CatEye SL-LD120 Wheel Safety Light:
This is an awesome light for night riding. Looks cool spinning in your spokes. I secured mine with zip ties and leave them on permanently. Makes people see you from the side, which is not always the case with traditional front and rear lights. I got a pair of these (same brand, different shop) months ago and love them so much I ordered this one for my boyfriend so that he will also be just as visible at night! The wording in the listing is ambiguous, this is JUST ONE light, not a pair.
Not extremely bright during the day or twilight, but I always use it at night. Extremely visible from side at night when wheels spinning. Now that daylight savings hit, I use them almost daily on my way home.
Bottom Line Yes, I would recommend this to a friend
