Goals from Lee Geum-min and Victoria Williams helped Albion defeat previously unbeaten Tottenham Hotspur 2-1 in the Barclays FA WSL.
And boss Hope Powell said they deserved the points.
The Seagulls bounced back from defeats by Aston Villa and Chelsea to go into the international break on nine points from five outings.
Powell said: “It was a good win and I thought no more than we deserved.
“We created a lot of chances and on another day could have had more goals.
"We had to be quite resilient at times and it got a bit tetchy but we matched them in that respect and I'm glad we came out winners.”
Tottenham had striker Rachel Williams sent off in the second half.
Powell said: "Credit to Tottenham, even with ten they punished us for not being switched on and after they got one back they went for broke and we had to defend well, which we did."
"We have a Conti Cup game on Wednesday at Birmingham City and it's a competition we want to do well in.
"But it's great for us, it will put us on a real high going into the international break and the time will give us the opportunity for a few players to rest little niggles, but we've got another big game first at St Andrew's and we'll concentrate on that first."
Spurs right-back Ashleigh Neville had two fursthal chancesm the seocnd of which forced a super save from Seagulls keeper Megan Walsh.
Albion’s first real chances of the half came through Lee and Inessa Kaagman, with the latter seeing her chipped effort strike the crossbar on 34 minutes, much to Spurs keeper Rebecca Spencer’s relief.
However, her relief was short lived when Lee struck minutes later with a low driven effort to give Brighton the lead.
The South Korean forward should have doubled the Seagulls lead on the stroke of half-time, but her effort was saved by Spencer’s legs.
After the interval, Albion went close to again doubling their lead through Danielle Carter, who like Kaagman, rattled the crossbar.
Carter then went close again on 65 minutes, capitalising on a mistake from Spurs left back Kerys Harrop, but her shot was saved by Spencer at her near post with ease.
Having been booked after just three minutes, Spurs talisman Rachel Williams needed to be careful to avoid another booking.
Unfortunately for the forward however, she picked up a second yellow on 76 minutes after an aerial challenge on Fliss Gibbons left the latter down receiving treatment, leaving Spurs down to ten for the final throes of action.
Albion doubled their lead on 85 minutes through centre back Williams, who prodded home her blocked rebound past Spencer.
Spurs grabbed one back through Kit Graham, who fought her way through the Seagulls defence to fire home past Walsh.
Albion: Walsh; Koivisto, Le Tissier, Williams, Gibbons; Kaagman (Green 82), Brazil, Simpkins (Connolly 59); Carter, Lee Geum-min (Symonds 73), Whelan.
