Possibly light is a combination of Quarks (and anti-particles)?...the building blocks of all subatomic particles.
But there are also Leptons and Bosons....
Bosons are thought to be the carriers of fundemental forces (gravitation, weak and strong nuclear forces, electromagnetic).
After all light as an EM wave has an electromagnetic component at 90 degrees to it's wave ...it can be polarized removing this force. thus it must have Bosons at work?
It gets even stranger.....
