The present invention provides a flashing lamp that can maintain a luminous intensity within a predetermined range even when at least one LED row of all the LED rows fails to illuminate. The flashing lamp of the present invention includes: an LED module (10) serving as a light source; a light distribution unit; a housing having an opening; and a light transmissive cover. The LED module (10) and the light distribution unit are disposed inside the housing, the light distribution unit is disposed on a light emission side of the LED module (10), and the light transmissive cover is disposed over the opening of the housing. The LED module (10) includes: an LED-mounting board (11); a plurality of LED rows (P1 to Pn); and an adjusting unit (C) that adjusts flashing of the plurality of LED rows (P1 to Pn) on a row-by-row basis. The plurality of LED rows (P1 to Pn) are mounted on one surface of the LED-mounting board (11), each of the plurality of LED rows (P1 to Pn) is a row in which a plurality of LEDs are electrically connected, and the plurality of LED rows (P1 to Pn) are electrically connected to each other on a row-by-row basis. When at least one LED row of all the LED rows (P1 to Pn) fails to illuminate, the adjusting unit (C) extends a flashing time of each LED of remaining LED rows to maintain a luminous intensity of the entire plurality of LED rows (P1 to Pn) within a predetermined range.
