An aircraft lamp includes a housing capable of being attached to a body of an aircraft; a discharge lamp; a reflector which reflects visible light from the discharge lamp; a light transmissive cover which transmits reflected light from the reflector to a front side of the housing; a lamp socket connected electrically to the discharge lamp and an igniter which activates the discharge lamp; and a high-voltage electrical power line that electrically connects the lamp socket with the igniter. The discharge lamp, the reflector, the light transmissive cover, the lamp socket, and the igniter are provided within the housing. A heat insulating air layer is provided between the lamp socket and the igniter. The high-voltage electrical power line is provided so as to pass through the heat insulating air layer.

A position measuring laser apparatus includes first and second laser transmitter-receivers and a position measure. The laser transmitter-receiver includes a laser beam emitter for emitting a laser beam, and a laser beam receiver for receiving a laser beam resulting from the emitted laser beam reflected from a reference reflecting mirror. An optical axis of the laser transmitter-receiver is oriented at a required angle toward a moving body. The position of the moving body with respect to the reference reflecting mirror is measured based on a beam receiving signal of the laser beam obtained by the laser transmitter-receiver. The position measure compares a drive signal for driving the laser beam emitter with a beam receiving signal generated by the laser beam receiver to measure the position of the moving body based on the beam receiving signal when the drive signal and the beam receiving signal coincide with each other.
