  • Vehicle multi-function led lamp with input current switch
    Patent number: 12065071
    Abstract: A multi-function vehicle lamp having a plurality of light emitting diodes includes a turn input and a tail input with a switch configured to stop current flowing through the tail input when the turn input is energized to increase current flow through the turn input to satisfy minimum current draw requirements of a vehicle current meter that detects turn indicator failure. The lamp may include a single combined turn/stop input, or may include separate turn and stop inputs. Lamps having separate turn and stop inputs block current flow through the stop input when the turn input is energized.
    Type: Grant
