Having used these on many a dull day, I can vouch for their ability to cut through the urban landscape. Comprising a 15-lumen front and 5-lumen rear, they were clearly noticeable from an impressive 200 metres away, with the fast flash setting proving impossible to miss, albeit not the easiest on the eyes...If you're a regular commuter or recreational rider and want a set of reliable lights to leave on your bike that maximise safety, these are a really good option.
