Do any of  you use buoys at night ?

I have...although its been a while lol.

I just put reflective tape on them from what I remember.

A couple of times, I've attached a small red and white bobber to a sinker to mark a bed during day, and come back to it at night.  Otherwise, no, not really.  Night fishing for me is generally a shoreline game.

Maybe I could duct tape a couple of waterproof flashlights to it . 

 

Better idea , glow sticks .

I use buoys when fishing grass beds, when I catch one I'll kick a buoy over, & fish it in an ever increasing circle. I'll pick it up & GPS it.

For offshore structure I use my depth finder & anchor off.

45 yrs on Toledo I don't usually need one

Small glo stick taped to the marker works good.
