One thing posters haven't mentioned is that most cars now have tinted windshields & the tint (even stock) is often darker than that of a generation ago. So motorists being blinded by bike lights is even less of a problem. Actually I've driven some friends cars with dark stock tint & don't like it at all, it makes it harder to see non-lighted stuff at night. It's a good trick to get car buyers to pony up for HID headlights? So anyway maybe we need brighter bike lights just to compensate for tinted windshields & distracted drivers. Durn y'all, now you've got me thinking about replacing my 300 lumen CygoLite! But first on shopping list is a nice tail-light like the Dinotte.
