More than 25,000 bids have already been received for the 12,000 tickets on offer.
Sunday, September 29, is the last day for revellers to be in with a chance of passes to the event in George Square on November 14.
It officially marks the start of the festive season for thousands of Glaswegians, making it one of the hottest tickets in the city.
To enter, log on to www.glasgowloves christmas.com and complete the form.
Anyone interested in applying who doesn't have easy access to the internet is advised to visit any of the city's 33 public libraries. Library staff have been briefed about the process and will help people set up email addresses and fill in forms.
Lord Provost of Glasgow Sadie Docherty said: "Tickets for this event are always in incredibly high demand, because it is a spectacular show that signals the start of the festive season for many Glaswegians.
"We have already received more than 25,000 entries for the Christmas Lights switch on, but the ballot application process ensures a fair distrib-ution of tickets.
"This really is a case of you have to be in it to win it, so if you haven't already, get online before Sunday to be in with a chance of joining us for what promises to be another amazing celebration this year."
Names will be drawn randomly and applicants advised if they have been successful by email on October 8.
Anyone can apply for up to six tickets, but people need to apply only once as only one application per address will be permitted into the ballot.
Full details of the event and who will be performing will be released nearer the time. It will start at 6pm and culminate with a fabulous firework display to round off the evening with a bang.
Each ticket permits access for one person and all adults, children and babies must have a ticket to be allowed into George Square.
