I built this circuit this am. How can I slow down the flash rate?

Increase the value of the capacitor or the resistors (I'm not sure which resistor, experiment).

I replaced the 47kohm resistor with a 100kohm variable one... Works great...

Built this bugger but one of the LEDs don't turn on. Anyone see a problem in my design?

 

[Justin]

Actually I just figured it out... lol. The LED was bad and I needed to make a jumper cable.

Built this circuit but the one LED stays on approximately twice as long as the other. Tried another 555 timer but the same result.

Dear Dave
Vi forum your light circuit for the train, wanted to build the circuit, but not how, I ask please tell me as hacerlo.Yo live in Colombia and here it is very difficult to find help.
Very friendly for your kindness
