Title: Method of replacing a conventional vehicle light bulb with a light-emitting diode array

Purpose. The patent addresses problems with conventional filament bulbs in vehicle warning light assemblies — excessive current draw, sometimes insufficient brightness, short life, and frequent replacement creating unsafe conditions. It notes LEDs can last up to 100,000 hours, draw less current, and emit more light than similarly configured filament bulbs. The invention is a conversion kit and method letting a user replace standard incandescent bulbs with an LED array.

Plain-language scope. The method involves: removing the lens and conventional bulb from the warning light assembly; accessing the assembly's electrical leads and connecting them to the LED array's electrical connector; securing the array to the assembly (e.g., screws through mounting-member apertures into assembly apertures, drilled if absent or misaligned); optionally connecting a license plate illuminating bulb to the warning light leads; and replacing the lens. The LED array generally comprises a mounting member and electrical connector connected to a circuit board having, in circuit, multiple LEDs, at least one resistor, and at least one diode. LEDs may be on one or both sides of the circuit board. Two connection variants are described: spliced wires, or a bayonet connector inserted into the assembly's mating bayonet connector receiver. Listed applications include taillights, headlights, brake lights, turn signals, dash lights, side marker lights, dome/courtesy lights, map lights, and reverse lights.

What the excerpt does not establish. It does not include the full claims, the abstract, the complete description, or the drawing content; claim scope, claim count, and claim limitations are therefore not verifiable from this text. It does not establish examination history, any prior-art references, validity, enforceability, or ownership changes. Classifications and legal-status entries are as listed by the source, which itself disclaims legal conclusions.

Assignment history

Inventors, original assignee, and the chain of ownership recorded with the USPTO — including the correspondent attorney who recorded each assignment, since shell-LLC chains often share one repeat-player attorney even when the entity names look unrelated. Surfaces NPE / patent-troll patterns: shell-entity transfers, known asserters in the chain, repeat correspondent fingerprints, pre-litigation assignments, and bankruptcy fire-sales.
