Review on OLIGHT Seemee 30 Bike Tail Light, 800M Viewable Range, 30 Lumens Rechargeable LED Lights With 230 Degree Visibility, IPX6 Waterproof Rating For Road And Urban Cyclists by Chad Moser

The light is of a higher quality compared to other bike tail lights on the web. This is a higher end flashlight brand that made a good quality bike light. I put them in the same category as Fenix. The light mounts easy, works well and great battery life. I never have to worry about it running out on a night ride.My only complaint is the different flashing functions. It has three modes and two of them are a "breathe" type flash that are not very conducive to catching attention of motorists. The flash function (the one I use the most) is a very quick flash that does not seem to utilize the full brightness of the light to it flashing so fast. I wish it had a slower flash function or one with a non-rhythmic flash that catches the eyes of car drivers. I use this in conjunction with a helmet light, and have been told by other riders in my group that they are a good combination and attract attention well.
