Yep, change the 470uF cap value to change the flash rate. Changing the 39K resistor would also change the flash rate. I haven't tried that circuit, but it sure is simple enough.

Note that the lamps are part of the circuit, so this one won't run without the lamps in place. It's also not really suitable for LED use, it was designed for incandescent lamps. There are many other similar circuits using the NE555 that will work for LED signals.
