Just the Tip Lights

Does anyone have any good ideas on how to use Just the Tip lights on Frabill Polar Therms?  Velcro on the light and the flag might be my next option.

I used velcro, it didn't take much and it was easily removable. I loved those tip up lights until I left them in a ziplock bag with some ice and they all corroded. Never replaced them but if I buy more I'd definitely go that route. I used them on my tip downs too, velcro on the handle so when the tip went down the light would turn on.
