Albion were not at their fluid best and rode their luck at times but Brighton took the lead in the 15th minute through Solly March as he netted his seventh goal of the season.
After a floodlight failure momentarily plunged the stadium into darkness, referee Peter Bankes stopped the match, apparently because his headset was no longer working.
There was a delay of a couple of minutes before play resumed.
It was perhaps an evening when only the result mattered and in the end Albion’s work-rate paid off and the saw out for the victory. The results adds more pressure on Palace boss Patrick Vieira, while Brighton continue their push for European qualification.

2. Steele - 8:
Excellent performance to justify the manager's trust in him. Made a few great saves early on when Palce were on top. Quick off his line on multiple occasions. Photo: Justin Setterfield
3. Veltman - 7:
Battled hard against Zaha and kept the forward quiet for most of the evening after a rocky opening ten minutes. Helped in attack. Great turn to get past Doucoure who could only bring Dutchman down and earn a yellow card. Photo: Mike Hewitt
4. Dunk - 8:
A couple of wayward passes early on as Palace put pressure on from the front. Quickly found his usual composure and snuffed out any chances Palace had. Photo: Mike Hewitt
