  We introduce shadow structures for singular knot theory. Precisely, we define
\emph{two} invariants of singular knots and links. First, we introduce a notion
of action of a singquandle on a set to define a shadow counting invariant of
singular links which generalize the classical shadow colorings of knots by
quandles. We then define a shadow polynomial invariant for shadow structures.
Lastly, we enhance the shadow counting invariant by combining both the shadow
counting invariant and the shadow polynomial invariant. Explicit examples of
computations are given.
