Hooking up light output through horn

Hey guys Ok well my boss has an old python system that the taillights got corroded and shorted out.. blew the internal curcuits for the light flash.. i'm going to follow the how to on the site but have no idea what the little circle with x and l in it is.. eveything else on the alarm works so why junk a perfectly good alarm? if someone could tell me what that circle is so i hook it up correctly would be great.. thanks alot guys https://www.the12volt.com/relays/page4.asp -MikeDriving a Bagged, Caddied 02 s10

That is a 552 flashing relay module. Go to any auto parts store and pick one up. Knowledge is power. But only if you apply that knowledge in a positive way, which promotes positive results in others.
