Disclosed is a lamp includes a light source that outputs light, and a mask that forms a beam pattern on a road surface as the light output from the light source reaches the mask, any portion of the reaching light is input thereto and then is output therefrom, and the mask includes a long distance area that forms a long distance pattern in the beam pattern on the road surface as long distance light in the light output from the light source reaches the long distance area, and at least a portion of the reaching long distance light is input thereto and then is output therefrom, and a short distance area that forms a short distance pattern in the beam pattern, which is located at a distance that is closer to the mask than the long distance pattern, on the road surface as short distance light in the light output from the light source reaches the short distance area, and any portion of the reaching short distance light is input thereto and then is output therefrom.

A rear lighting assembly for a tank vehicle. The rear lighting assembly includes a signaling device that operably engages with one of a rear bulkhead of the tank vehicle and a false bulkhead of the tank vehicle. The rear lighting assembly also includes a processor that electrically connects with the signaling device for commanding the signaling device to emit a set of indication lights through the false bulkhead and behind the tank vehicle. The rear lighting assembly also includes a power source that electrically connects with the signaling device and the processor. The rear bulkhead is made of a first material that reflects the set of indication lights emitted by the signaling device. The false bulkhead is made of a second material that is different than the first material and that transmits the set of indication lights emitted by the signaling device.
