This page is wrong. The spinning lights are called, "Beacon Lights", "Klaxon" is the name for the electronic sound generators that make the alarm noises.
This page needs to be fixed so that it's not referecning the lights as klaxons, or change it to be "base alarms" and cover both beacon light deployment and the various klaxon tones used in the SGC - 15.195.201.89 02:24, September 30, 2013 (UTC)
