Abstract
A laser readable surveying rod is provided with adjustable lighting elements. More specifically, lighting elements, such as LED lights are provided along a length of a surveying rod such that laser readings may be taken at night or in dark conditions. Lighting elements may be translated along a length of a rod, particularly where it is desirable to illuminate only a portion of a rod and conserve valuable energy.
