The Manchester-born singer, whose surname is Shahmir, is seen partying in South America in the clip, which also features Ms Dynamite.
The song - produced by drum and bass DJ Shy FX - marks the third release from the star, after 'Finish Line' peaked at number 13 on the chart in May this year.
The singer was recently nominated for 'Best Newcomer' at this year's MOBO Awards, before supporting Snoop Dogg for a string of his UK tour dates.
Yasmin recently described her sound to Digital Spy as "What the f**k?" music, adding: "It's different, it's fresh, it's soulful - there's elements of hip-hop."
'Light Up The World' is available to download from January 15.
