ル／ストツプ切換ＬＥＤ灯具。 A plurality of LED elements disposed on a substrate and provided with current limiting means is used as a light source, and the current applied to each of the LED elements is changed to an appropriate ratio by a tail/stop switching circuit to perform a tail function and a stop function. In the tail/stop switching LED lamp, the current limiting means is omitted, and the tail/stop switching circuit is provided outside the board, and a fixed resistor is connected in series to the output end of the tail function. A tail/stop switching LED lamp characterized in that the end is connected directly to a constant voltage circuit.
