A line of illuminated electrically powered exit indicators, each having a power backup is mounted on one surface of a non-conductive tape-like support which is flexible enough to be formed into a roll and bend around corners. The exit indicators and the electric circuits are mounted on one surface of the support. A strong adhesive is applied to the opposite surface of the support so that the exit indicators can be easily attached by the adhesive to surfaces of corridors. The tape-like support is provided with a device which permits the tape-like support to be easily unrolled without stressing the electric circuits on the surface of the tape-like support roll.
