Flashing Red Toggable Light

How would you go about making one of these?

I’ve failed at doing such a simple thing in Wiremod. I’m finishing off an alarm system in my base. When I press the button the siren goes off and a bunch of red flashing lights start to go off aswel.
So can anyone tell me how to make a Flashing Toggable Light (Button).

It’s pretty basic wire. There are a few ways to do it with gates. You can use a Square Pulse gate or a Monostable Timer gate linked to a Pulser gate.

As I’m not good at Wire at all, would you be able to specifically tell me what to wire together? Thanks for reply.
