L550 White & dual White/Red AD
Medium intensity LED obstacle light
Obstacle light for day and night time marking of structures that present a hazard to aviation. This L550-XXX-AD is specifically designed for the replacement market. White flashing in day and red flashing/steady burning in twilight and night mode. This specific L550 is using the same visual flashing characteristic as its predecessor the L450. Improving interchangeability and integration within a field of existing obstacle lights.
