PROBLEM TO BE SOLVED: To ensure high reliability by making the structure of a drive circuit for light emitting elements simple in a vehicle direction indicator that sequentially turns on the light emitting elements arrayed in a longitudinal direction, and to provide an inexpensive drive circuit, device and method by achieving a drive circuit configuration that can easily be mounted on a circuit substrate on which the light emitting elements are arrayed.SOLUTION: A drive circuit for vehicle direction indicator comprises: LEDs 20 to 2n arrayed, each having a pair of terminals; and a plurality of pieces of buffer circuit means 10 to 1n connected in series in many steps. One terminal of each of the LEDs 20 to 2n uses a common terminal and is connected to power source means 51. The other terminal of each of the LEDs is connected to the output terminal of the corresponding buffer circuit means 10 to 1n. In the buffer circuit means 10 to 1n connected in series, delay circuit means 30 to 33 are inserted between the p
