My experience tends to differ. I build a lot of Bluecor foamies. I found at times due to distance and light, they could be difficult to see up there in a blue sky.
I found some very thin, lightweight red reflective tape at an automotive parts store that I put on all my Bluecor foamies. It makes a world of difference. I usually put it on the stabs and/or rudder so it's visible during normal flying. Just a small amount I can pick out of the sky from across the field.
I tried a few different "reflective tapes" until I found this one; very thin, light and very easy to see. In fact this manufacturer has two colors, orange and red...the red works much better.
Had I quit after trying the 1st reflective tape I tried, I'd agree they don't work. But for me, this stuff is great. I buy 2 rolls of it at a time, when I can find it.
Here's my Insulator that I flew this morning, with the tape on the stabs...a real god-send for these aging eyes.

Sorry, I just re-read the original post and missed the whole point of the "LED illuminated night flying" part....didn't have my coffee yet.
My T-IFO is highly illuminated with LEDs as is my "dusk flyer". Flashing red and flashing green navigation LEDS, and lots of bright white LEDs illuminating the plane. Works OK at dusk, never really tried night flying. I've got one "LED headlight" to help with orientation, but illuminate the plane as best as possible for best visibility. I found bright white LEDs work best.
Your milage may vary.
