For the second time in 2 commutes, I've had a cyclist/commuter come up behind me, pass me, and remark about how visible I was as we rode in the dark.

I think I take lighting to a ridiculous degree. I have a road worker's day-glow reflective vest on over my winter jacket. I have a headlight, a flashing light on the back - and front - of my helmet, a light on my rack, and a light hanging from my pannier. That's 3 tail lights and 2 headlights. I have reflective trim or tape on the pannier itself, on the rack, on the rear fender, and on various spots on the frame and wheels.

So a guy came up and passed me on the MUT tonight and said "Wow. No one can ever say they didn't see you!"
"Good," I replied. "Then I know it's working, cuz that's my intent."
I also know it's working when car after car crosses the double line to give me w-i-d-e berth when passing me on the road.
