NOVELTY - The auxiliary device is characterized by an internal structure with a rechargeable battery (1) fixed by a contact adhesive (2), which is connected by cabling (3). The battery conducts electrical current to lamp type light emitting diode (LED) (4), that can be activated by a key switch (5), which is also connected by the cabling. The diode rectifier current from a solar panel (7) maintains the electrical charge of the battery, which also has cabling connected to a diode chain or to an external female type connector (9) providing better electrical recharging with an external bi- volt source.    USE - Auxiliary device for providing recharge for electrical signals, particularly with solar charge. Uses include but are not limited to public signal, automotive, rail, marine, aviation, road signs or billboards.    ADVANTAGE - The auxiliary device is characterized by an internal structure with a rechargeable battery fixed by a contact adhesive, which is connected by cabling conducting electrical current to lamp type light emitting diode, that can be activated by a key switch, which is also connected by the cabling and the current from a diode device or solar panel keeps the electrical charge of the battery, which also has a cabling connected to a diode current or to an external female type connector providing better electrical recharging with an external bi- volt, and thus the arrangement provides better efficiency and performance in lighting because of no requirement of adjustment of battery or wiring vehicle, and thus provides a compact eco-friendly lighting as a renewable energy source and is also maintaining a long-term operation, lower maintenance costs in its structure, low cost of installation in vehicles and easy removal.
