  • Patent number: 10481380
    Abstract: An adjustable reflecting device is disclosed. The reflection of a light emitting diode (LED) or a similarly lighted appliance relayed to a more accessible viewing location is accomplished by using 2 planar reflective surfaces (mirrors) situated in a housing. The mirrors are adjustable to direct the reflection of the intended image or lighted object to the observers eye. The first mirror (housing mirror) reflects the image and relays it to the second mirror (tube mirror) through adjustments made by the observer. Once the adjustments are made, the mirrors can be locked in the position from a desired location for viewing.
