you can go to Harbor Freight and buy a reflective vest for $5. The ones at the big box hardware stores probably cost a little more

I did my first Super Randonneur series and an R12 on the bike I raced from 1980. It was a real racing bike, very similar to the ones they sell now except for steel. I didn't take the lighting seriously enough until the rainy disaster of my first 400k. For the 600k, I put the dynohub wheel from my commuter on my long distance bike.

I used 2 Planet Bike Superflash rear lights until PBP, where I got a rear dyno light. You might have to change batteries on the PBSF if you keep it on solid and ride through the night.
