1. A flexible lighting strip for use in an aircraft cabin, the flexible lighting strip having a minimum bend radius of no more than 40 mm, and comprising:
a flexible track comprising a channel extending along the length of the track, the track extending along at least substantially all of the length of the flexible lighting strip; and
a flexible inner component within the channel, the inner component comprising lighting components arranged along the length of the inner component, wherein an upper face of the inner component is at least substantially exposed, and lower and side faces of the inner component are at least substantially contained within the track;
wherein the track comprises two inwardly-directed protrusions extending from opposing sides of the channel, each of the protrusions extending into the inner component and increasing in width within the inner component, the protrusions being arranged to hold the inner component within the track even when the track is deformed, holding sidewalls of the channel to the inner component so as to reduce splaying of the channel.
