An LED wedge-based lamp and method of making the lamp, where the lamp has a generally planar circuit board having one end that has electrical connections exposed thereon and a connecting part that is adapted to mechanically couple the lamp to a wedge-based lamp socket. The lamp includes an LED light engine near a second end of the circuit board, where the light engine includes plural laterally aligned LEDs whose light output mimics the light output of an incandescent lamp, such as used in automobile stop and turn signals. The lamp includes a load resistor, whose load mimics that of the incandescent lamp, on an exterior surface of the connecting part. The connecting part may be a sleeve that slides onto the circuit board. A hand grip/heat sink may be provided at the second end of the circuit board.

Abstract:
A light emitting diode bulb () has a base (), with a printed circuit board () contained therewithin, a plurality of electrical connectors () having a first end () mounted upon the circuit board () and a second end () extending away from the base () in a direction normal thereto. Each of the electrical connectors () comprises at least a first electrically conductive plate (), a contiguous insulator () and a second electrically conductive plate (). A light emitting diode () is electrically connected between the at least a first electrically conductive plate () and the second electrically conductive plate () adjacent the second end () on each of the plurality of electrical connectors ().
