On my Lionel diesel the blinking is not from the bulb itself but from a connection to a circuit board that performs the blink. I tried to simply replace the GOW bulb with an LED using the existing wires but it didn’t work. After some posts here I discovered that an LED doesn’t draw enough voltage for the circuit to think there’s a bulb there (my explanation, not a technical one). A triac (I think) was also needed before the LED. By using the original circuitry you can turn the flash off with your CAB, but that wasn’t important to me. I ended up using a flashing LED bought from Evans and just connected it directly to track power. Since the little plastic housing it goes into is colored you can get a white or colored bulb. If you get white, make sure it’s warm white since a cool white may look to white.
