Leading scorer Glenn Murray took his tally to 19 with a stunning second-half strike to clinch a seventh consecutive win for Brighton in a 2-1 triumph over struggling Swindon.
Murray took his side 13 points clear at the top of League One by expertly dispatching a low shot across keeper David Lucas in the 64th minute.
Irish midfielder Gary Dicker put Brighton ahead with a 12th minute penalty but spirited Swindon levelled midway through the first half thanks to a wonder strike by David Prutton.
Dicker had a second penalty saved before Murray's clincher and Brighton have now won their last 10 games in a row at home.
Brighton broke the deadlock early on when Craig Noone's penetrating run into the area was ended by Andy Frampton chopping him down and Dicker stepped up to send Lucas the wrong way from the penalty spot.
Swindon equalised after 22 minutes through former Southampton midfielder Prutton, who scored with a tremendous 25-yard drive into the middle of the goal.
Brighton were awarded their second penalty after 61 minutes when Frampton was adjudged to have pushed Murray but Dicker's poorly-struck spot-kick was saved by Lucas.
Swindon were unlucky moments later when a fierce shot by Mike Grella cannoned back off the underside of the bar.
But Murray restored the Seagulls' lead by superbly drilling home across Lucas and into the far corner.
