If, at the end of three rounds, there are still lights left on, the bachelor will turn off all but two of the remaining lights himself.
He will then have a chance to ask one question to the last two women, before choosing which woman he wants to go on the date with by turning off one more light.
The objective of the show is for a single man to obtain a date with one of thirty single women.
The women stand on stage underneath thirty white lights, each with a button in front of them.
A single man is then brought down on stage via the 'Love Lift' and tries to persuade the women to agree to this date in a series of rounds, playing a pre-recorded video discussing his background, displaying a skill (such as dancing or playing a musical instrument), or playing another video in which the man's friends or family reveal more about his virtues and philosophy.
Then they meet, go up the big stairs opposite the love lift and have a backstage interview.If the man is left with two lights at the end of round 3, he will just ask his question to the two remaining women and if there is only one light left at the end of round 3, he will go on the date with that girl without asking her his question.There are usually four men brought on in the course of a single episode, though on some occasions segments have been cut and only three men have been shown.An unscreened pilot episode was made for Channel 4 in 2009, but it was ITV who picked it up for a series.The show is produced by Thames (formerly Talkback Thames).
