This doesn't technically count as a commute, but I wanted to share the story here:
A bike club buddy and I were riding home from the group ride last night, in late dusk. We noted an approaching pick-up in our mirrors and went single file on the shoulder.
He passed us with plenty of room and shouted out the window: "I like your lights!"
I was on my Level.2 eBike, which has three tail lights built in and I have two on the back of my Lumos helmet as well. My buddy had his Bontrager Flare strobing. It is blindingly bright; too much so at night.
It felt good.
Here's what my Level.2 looks like from behind at night. The bright one is on the rear fender, and the dimmer ones are on the seat stays. They're even visible with the panniers deployed, at least as seen from directly behind. Having more than one light going helps the motorist determine distance.
