Earlier this week I was sitting on the side of the road next to my house talking to a neighbor. I was on the bike. All the lights were running.
Another neighbor turned onto the street and yelled "Geesh...think your lights are bright enough? I saw you from way down the street!"
All I could do was thank her for verifying how effective they were for me.
(She wasn't being nasty. She s very nice. She was just surprised as how far away she would see the lights)
