Light Night gets under way this evening and tomorrow, with more than 60 installations brightening up the streets.
Now in its 13th year, the free event will include a mix of huge digital projections, interactive displays, performances and child-friendly activities.
These include a series of giant lamps illuminating Briggate, a projection on Leeds Civic Hall celebrating the city and a parade featuring performers from Leeds West Indian Carnival.
The parade is due to kick off from The Headrow at 7.30pm tonight.
A life-sized interactive game zone featuring 12 activities inspired by arcade classics will Kirkgate Market tonight and tomorrow between 3pm-11pm.
A street theatre production from drummers at Spark! will combine high impact percussion with elaborate light design on Briggate from 9.30pm tonight and Victoria Gardens at 6.30pm tomorrow.
The West Yorkshire Playhouse will on both nights host three giant, translucent heads which come to life using 3D mapping to show the faces of the audience. This takes place between 7.30pm and 11pm.
And these are just some of the many events comprising the festival over the next two days.
Coun Judith Blake, leader of the council, said: “Light Night Leeds is one the biggest, best and brightest occasions on our city’s calendar and brings together 80,000 people to experience something truly unique and unforgettable.
“There really is nothing like the atmosphere on Light Night and the sheer colour and creativity of the imaginative installations which transform our city each year is genuinely awe-inspiring.”
Brochures will be available to buy for £2, with all proceeds going towards keeping the event free in the future.
Information points will be located on Victoria Gardens and Briggate.
Car parks and street parking will also be available throughout the city, with special offers at The Tetley gallery, Trinity Leeds shopping centre, the University of Leeds, Merrion Centre and Whitehall Road.
And the Light Night Rider, a free hop-on bus service, will also be making stops around the city.
