The invention provides conspicuity devices and methods. A first embodiment includes a glove with at least one elongate lighting device adapted and configured to admit light having an advantageous spectral energy distribution. Additional articles of clothing are provided herein for enhanced conspicuity, such as for emergency workers and athletes.

A lighted horse halter includes a number of halter pieces and a portable electric power source is supported by one of the halter pieces. A light source supported by one of the halter pieces is responsive to electrical power received from the portable electric power source for outputting light. A side-glow optical fiber supported by one of the halter pieces is responsive to the light output by the light source for outputting light transverse to a side wall of the optical fiber. The optical fiber can be sandwiched between the nose band and a protective cover that can include fluorescent material.
