The present invention relates to stable substantially non-aqueous, non-alcoholic, non-silicone, foamable carrier compositions comprising petrolatum or mixtures thereof, at least one foam agent, at least one propellant, and with and without the addition of an active agent. The device is housed in a molded plastic enclosure in a rectangular shape and includes an emergency light, night-light, flashlight, and power failure alarm. The reflected light is transmitted through the substrate, which is preferably made of silicon and transparent to wavelengths of light used in DWDM systems. With this device, if a user does not rotate his or her hips at the correct time, then the user’s hands will encounter the forwardly extending rod that is affixed to the user’s waist. The imaging system may be operable in combination with a magnetic field sensor of the magnetic compass system to provide a substantially continuously calibrated heading indication, which is substantially resistant to local magnetic anomalies and changes in vehicle inclination.
