collision between a BoxCollider2D and a SphereCollider?

I have my player as a quad with a 2D box collider on it, and a point light with a sphere collider set to be a trigger, but cannot get the OnTriggerEnter/Exit functions to work. Is this because of the mix of 2D/3D and if so does anyone know of a work around?

u can create an empty gameobject and attach it to ur desired game object(the 2d one in ur case) then check for on collisionenter or istrigger
