Preventive maintenance undercarriage lights
View Patent ↗Undercarriage lights are positioned under a truck adjacent to parts of the truck requiring regular visual safety inspections to light up the parts. A control module operates the lights in coordination with an ignition switch, a manual switch outside the truck, a timer, a low light sensor, and an indicator light.
1. A preventative maintenance undercarriage lighting system for a truck to increase visibility in poor lighting conditions for visually performing safety inspections under the truck, the system comprising:
a plurality of lights mounted on the undercarriage of a truck adjacent to parts of the truck requiring regular visual inspection to cast light thereon to enhance visual inspection;
a control module wired to the lights for operating the lights;
an ignition trigger wired to the control module to turn on the lights when the truck is started;
a manual trigger device wired to the control module, the manual trigger device mounted on an outside portion of the truck for a user to activate the plurality of lights while the user is outside of a cab of the truck;
an automatic timing control module wired to the control module to control the amount of time the lights stay lighted;
an indicator light in the cab wired to the control module to remind a user that the undercarriage light is on and remind the user to perform a walk around inspection.
2. The system of claim 1 wherein at least one of the plurality of lights comprises a retractable light comprising a light enclosure attached to a part of the truck, the light enclosure housing a retractable lighting fixture therein, wherein when each light is energized, the lighting fixture lights up and extends out from the light enclosure to light at least one adjacent part of the truck needing visual inspection, and when each light is turned off the retractable lighting fixture retracts into the light enclosure to protect the retractable lighting fixture from road debris.
3. The system of claim 1 wherein at least one of the plurality of lights is attached to the undercarriage of the truck in a location so that it aids in the visual inspection of at least one visual inspection item taken from the list of visual inspection items including fluid leaks, engine oil leaks, hydraulic oil leaks, engine coolant leaks, gear oil leaks, and tire air pressure in rear inner tires.
4. The system of claim 1 further comprising a low light sensor switch wired to the control to turn on the plurality of lights under low light conditions.
