An indicator display (20) comprises a fluorescent plastic first member (30) of a first color and having a first face (40) and a fluorescent plastic second member (32) of a second color, different from the first color, and having a first face (42). One or more first light emitting diodes (60) are between the first member and the second member and positioned to illuminate the first member preferentially to the second member. One or more second light emitting diodes (62) are between the first member and the second member and positioned to illuminate the second member preferentially to the first member.
