Seen the light?

My first attempt at light trails and this weeks entry into the WBC.
I can't remember if it is potential, kinetic, radiant or one of the other light related ones.
But then, I quit the A-level Physics class on day one for reasons known only to a 16 year old me.
Well happy with this though, and I think, 'full' of energy.
Oh, it's the bridge over J3A looking westbound on the M8.....n that, by the way..
