Glow in the dark tape on the front and back of my phone and on the tips of the chargers to make them easier to find in the dark.
For the same reason my phone case is the brightest colored one I could find.
I had to get some clear heat shrink tubing to put over the charging cable ends to hold the tape in place otherwise it unravels after a few days use.
Sure they make lit USB cables but not in 20ft+
I’d really have preferred to have a bright solid glow in the dark phone case but for whatever reason barring I have one 3d printed (which will then not have the same protection of a normal cheap rubberized case) there isn’t anything like that available.
