ABSTRACT:
An electronic oil level indicator is provided to show the amount of oil in an oil pan of an internal combustion engine which consists of a perforated housing positioned in the oil pan, so that the oil in the oil pan will enter the housing. A mechanism is connected to the housing for producing light. A fiber optic bundle has a first end connected to the housing spaced away from the light producing mechanism within the oil. A display panel is remotely located from the housing with a second end of the fiber optic bundle connected thereto. The height level of the oil will control the amount of illumination from the light producing mechanism reaching the fiber optic bundle which in turn is carried to the display panel to allow a person to visually check the oil level on the display panel.
