I have seen this exercise in Bergman: Universal Algebra: Fundamentals and Selected Topics. Let $L$ be a distributive lattice and let $2$ be a 2-element lattice. Show that there is a set $J$ and lattice embedding $h: L \rightarrow 2^J$ such that for every $j \in J$, $\pi_j \circ h$ is surjective. ...
