Options

m_iOnStyle	Light style number used when the light is on.
m_iOffStyle	Light style number used when the light is off.
m_iTurnOnStyle	Light style number used while the light is being turned on over time.
m_iTurnOffStyle	Light style number used while the light is being turned off over time.
m_iTurnOnTime	How many seconds (an integer, not a fraction) it takes to turn on the light with the light style in m_iTurnOnStyle applied.
m_iTurnOffTime	How many seconds (an integer, not a fraction) it takes to turn on the light with the light style in m_iTurnOffStyle applied.
firetarget	Target that will be activated when the light switches to the “On” or “Off” state.

As before, you can use pattern only for lights that are on, and light styles for lights that are being turned on or off are limited to the standard set numbered from 1 to 19. This technique can be used for faking luminescent lamps, which flicker while turning on.
