just hide it. And, like the others said, tape the two conductors so they
cannot ever touch each other.
You never know if you'll want to use it in the future. Maybe you won't
like the light and want to sell it. Or,
I'm not sure why you don't want to wire the rear taillight. Super easy.
Takes 5 min and some zip ties. I love it. Never have to worry about any
lights or recharging. I run the wire along the underside of the frame and
up the rack. You never see it. I'm not mechanically inclined and I can
Just insulate the taillight connections with tape (or better heat-shrink)

but if you cut off the wire and leave a fews inches you could undo it
