Is it possible to turn on/off light using sop in houdini; vex?

I want to turn on/off light and set light color at random.

Hi,

yes it's possible. You can use value of attributes from SOP. See simple example i attached. I've animated parameters Enable and Color of Light object. Click RMB on parameter Enable: Expression -> Edit Expression and you can see an expression.

You can use CHOP for this also.
