Josh Short scored his third goal in four games to put the Golds ahead six minutes in but Tommy Blennerhassett levelled nine minutes later.
The draw keeps Littlehampton 11th in the table with three games to go, and a top-half finish is still possible.
Lancing need one win from their final two as the table stands to make sure they finish outside the relegation play-offs.
