The Lions returned to winning ways in Dingwall thanks to a stunning second half double from Bruce Anderson
The visitors were holding out against a County barrage when they broke upfield and scored the 66th-minute opener, Anderson stretching to connect with a Steven Bradley cross.
Three minutes later Anderson had his second, picking the ball up on the halfway line and charging towards the County box before firing low into the net.
The win is Livingston’s first since 8 November and moves them above St Mirren, but County remain rooted to the bottom, three points from safety having played two games more.
Both sides were looking to address rotten runs of form, with neither having won for over eight weeks. The first-half showed why. Although there was plenty of effort, there was very little quality on show in either box.
The only glimmer of hope came when Andrew Shinnie buried Anderson’s through ball, but the offside flag went up straight away. The VAR check revealed it was the right decision – by a matter of inches.
In the second-half, County began to pepper the Livingston goal and both Ross Callachan and David Cancola should have scored.
The former received the ball unmarked in the box, swivelling and driving a shot straight at the legs of Shamal George, before Cancola showed excellent composure in the box before passing wide from six yards out.
George was then alert to tip a Keith Watson effort over, and it looked more than likely that County would eventually break the deadlock.
But it was Livingston who nudged themselves ahead when Nicky Devlin and Bradley surged up the right, with the former Hibs winger cutting back to Anderson, who netted with composure.
Three minutes later, they had a second. Picking up the ball on the halfway line, Anderson had one thing in his mind, charging straight at Connor Randall before shifting the ball onto his right and lacing it low into the bottom corner.
With that, County were practically out of the game and were denied a tense finale when Jordan White’s header was ruled out because Callachan was offside in the build-up.
