attaching a first cover to the first top surface of the light guide; and
attaching a second cover to the first bottom surface of the light guide, wherein the light source, the battery, and the power switch are located between the first cover and the second cover.
11 . The measurement system of claim 8 , wherein the step of coupling the first lighting portion to the light guide includes configuring the first lighting portion to be detachably couplable with the first lighting portion with the light guide.
12 . The measurement system of claim 11 , wherein the process further includes:
detaching the first lighting portion from the light guide, wherein the first lighting portion includes a first texture; and
detachably coupling a second lighting portion with the light guide, wherein the second lighting portion includes a second texture.
13 . The measurement system of claim 8 , wherein the process further includes:
disposing a light source, a battery, and a power switch on the first lighting portion; and
electrically connecting the light source and the battery to the power switch, wherein the power switch is used to power the light sources or stop powering the light sources.
14 . The measurement system of claim 13 , wherein the process further includes electrically connecting a charger port to the battery, wherein the charger port can be connected to a power source to receive electrical energy for charging the battery.
15 . A method of manufacturing a measurement system, comprising:
providing a first ruler portion, including:
