An owner finds the clips too short to adequately secure to bags.

Bottom line

The Lumos Firefly Mini is a 30-lumen bike light that can be programmed as a white headlight, red taillight, or yellow turn signal (with two). This light has three flashing modes only. Testers who say it's adequate to be seen both night and day praise the creative features and versatile mounting options. However, two or four lights are required to take advantage of most of these features, which is expensive. The versatility of the Lumos Firefly Mini lights may appeal to some, but there are many cheaper but equally effective bicycle lights available.
