They are LEDs you can pretty do whatever you want with them.
you can make them be on all the time.
you can make them blink like a turn signal.
you can make them part of your alarm system.
you can make them come on when you use your parking lights.
None of which i would suggest unless you know a little about wiring...because most of the methods will require you to tap into other sources. My halos, i have them wired so they work with my parking lights.
EDIT: it would be cool to take one out and install a strobe in it...
