There was nothing to separate the sides at the break with neither Leicester nor Brighton able to wrestle control of a mediocre game.
Patson Daka fired Leicester into the lead 30 seconds after the re-start after James Madison and Harvey Barnes combined.
Albion looked more lively after going a goal behind and the introduction of the electric Tariq Lamptey and Danny Welbeck sparked life into the attack.
And it was Welbeck who netted the leveller when he rose at the far post to head home a pinpoint cross from Neal Maupay.
Albion extend their unbeaten run to six matches and are ninth in the table on 30 points. Great end to the match after a poor first half display.

5. Marc Cucurella 5
Caught in possession on a number of occasions. Has been excellent since his arrival but not at his best today.
6. Steven Alzate 6:
Did his best to break up the play and kept things tidy in possession. Decent display and subbed with 20 go for Welbeck
7. Pascal Gross 5:
Looked a little off the pace in the first half. Even his famed Cruyff turned failed him on one occasion. Not his day.
8. Alexis Mac Allister 5:
Blasted an effort high into the stands on the half hour when should have done better and then did the same at the start of the second half. Not his best game and gave the ball way too often.
