Zaha's second, a bullet header from Luka Milivojevic's cross, was particularly impressive, but Brighton, who before this game had scored only seven away goals all season, responded with a close-range effort from Glenn Murray and a sublime finish from Jose Izquierdo.
The second half was never going to top that as Palace guarded their lead against fierce Brighton pressure, with Murray twice going close against his former club. But Palace keeper Wayne Hennessey held on to earn Palace their first home league win in three months.
