If the weather is gloomy then I will use a light on flash mode, I currently use a Blackburn Mars 4 but will upgrade this spring when lights go on sale to probably a Light & Motion Vis 180 or the Serfas Shield but I haven't decided completely yet on either.
Here's a scenario: Someone is texting. They look down at their phone. They glance up and look for large moving objects (other vehicles). They look down at their phone. They look up for a second.... I think in these situations, even during the day, a flashing light can help. It can catch the eye in a way that a cyclist without a light might not. Same in the morning when the drivers are half asleep. Not that this is perfect or takes away all the risk, but if I can spend $30 - 40 for a little safety upgrade, that would be worth it to me.
I said in my first post that I didn't expect these lights to be visible on a bright sunny day. What I'm wondering is if a 1-watt light is a sufficient upgrade for overcast conditions to be worthwhile.
Edit: The Serfas looks pretty good. Thanks for the suggestion.
