For my tail light I'm using an adhesive backed flexible LED tail light with signals off ebay here. Since I'm using the minimalist drag specialties momentary push button I needed to use the motogadget m.relay+ to take the momentary signal and create a prolonged signal pulse. pretty slick unit. I finished up the mount. I originally wanted to integrate the LED into the rear hoop but its a pretty small diameter and I didn't think it would fit and still look good. So I went with a bending a piece of 1"x1/8" flat bar to mount it right under the rear hoop and welding it to the frame. I think it fits the minimalist/ low profile look and is visible and easy to replace (since it is a $2 china ebay part...).
