Light Shift never won another race, being beaten by Peeping Fawn in the Irish Oaks and the Nassau Stakes and finishing unplaced in the Prix de l'Opéra.

Light Shift was a bay mare with a white star bred in Kentucky by Flaxman Holdings a breeding company run by the Niarchos family.

Before Light Shift, Lingerie had produced the Prix Jean de Chaudenay winner Limnos and Shiva, a mare who won four races including the Group One Tattersalls Gold Cup.

[2] The filly was trained throughout her career by Henry Cecil at his Warren Place stables in Newmarket, Suffolk and was ridden in all of her races by Ted Durcan.

[citation needed] Light Shift began her career in a six furlong maiden race at Newmarket in June in which she finished second, half a length behind the winner Wid.

[5] In the Oaks at Epsom on 1 June, Light Shift started at odds of 13/2 in a field of fourteen fillies, making her the fourth choice in the betting behind her stable companion Passage of Time and the Irish runners All My Loving and Four Sins.

[7] In the Irish Oaks on 15 July, Light Shift was again matched against Peeping Fawn, who had won the Group One Pretty Polly Stakes in the interim.

Light Shift, the 9/4 favourite despite her trainers concerns about the soft ground,[8] raced just behind the leaders before taking the lead in the straight, but was soon overtaken by Peeping Fawn and finished second, beaten three and a half lengths.
