ABSTRACT:
An illuminated caliper device includes a caliper assembly having first and second caliper legs each having a pointed tip and a pivot end. A pivot support and first and second pivot elements pivotally connects the pivot ends of the first and second caliper legs to the pivot support. A battery housing attached to the pivot support contains a battery. First and second light emitting diodes are coupled by a switch mounted on the battery housing to first and second terminals of the battery and produced light that is directed to areas of the surface to be measured by pointed tips of the legs. The intensity and color of light emitted by the first light emitting diode are such as to sufficiently illuminate the surface under low ambient illumination conditions without disrupting acquired night vision of a user.
