Phillip Roberts scored a hat-trick to secure victory for Falkirk at the home of Scottish Championship rivals Livingston.
The former Inverness Caledonian Thistle player swept the Bairns ahead from Rory Loy's cutback.
Roberts then outpaced Callum Fordyce to fire his second of the day before the break.
And the scoring was completed when the 19-year-old headed Loy's cross into the net in the second half.
