I don't usually ride late into the night and there are street lights for the majority of the path that I take, so I only have two lights currently.

In the front, I have a Cygolite Metro 360. In the evening hours, I usually have the setting on the pulse mode. If it's really dark, cloudy or the sun has gone down, I'll have the mode where the light flashes a couple times like a lightening bolt in the sky at a regular interval.



In the back, I have a CatEye Rapid 3. In the evening hours, I'll have the light blinking, but when it's really dark, I'll have the light flashing faster as if it were having a seizure.



I'm probably gonna start riding some trails in the evening and for that, I'm thinking of getting a CatEye Volt 300 and mount that on my helmet so when I turn my head, I can illuminate what I'm looking at as well as get a wider angle of light.
