I added them to the alarm system because green light can be detected by the human eye (and silicone devices - ie any camera you and local law enforcement can buy) in both cases . darkness and day conditions. They're bright enough for the power draw, are compact, and can survive in automotive environments (which pretty much means the consumer will use them anywhere). They have easily adjustable flashing patterns and low power consumption. In my case, the application is an addition to a house alarm
