A modular LED warning lamp has a base, a lamp module and a lamp shade. The lamp module is mounted on the base and has a positioning sleeve, multiple circuit panels and a circuit board. The positioning sleeve has multiple positioning sections formed and arranged circularly on an outer wall of the positioning sleeve. Each circuit panel is mounted individually on one of the positioning sections and has at least one LED. The circuit board is connected electrically to the LEDs. The circuit panels can be selectively mounted on some specific positioning sections to achieve a desired emitting angular range. Additionally, The circuit panels can be standardized to various types, which with different numbers of LEDs for use in the positioning sleeve. Such that, time and cost for developing a warning lamps with specific brightness and emitting angular range are reduced.
