First go at writing a riddle, here goes:
I am the light that shines in the dark
Sometimes I've a friend to whom you should harkThere's no match for me,
I'm buzzing with energyIf you see me, you might be too near
Perhaps your direction, you need to shearDon't get too salty, please don't pout
My head keeps twisting around and about
Might be fairly easy to ardent puzzlers, but hope you enjoy!
