Electronic switching board?

Would Arduino be an option here?

I gotta admit, I would think there have to be boards premade that can blink every...5 seconds? What flash rate are you looking for?

Hi, you know you could put flashing Leds in whatever color you would like and led's only draw milliamps instead of amps, very easy to change! see below just for idea's

How about a Dallee (or other manufacturer) alternating crossing signal circuit board and just use one output?

Check "Evans Designs" website.   They may have something that will work for you.

There are "electronic flashers" that are made for the older automobiles also.  May require a 12V ground connection also.

There are several vids on YouTube on how to make a flasher with a 555 chip. But, then, it depends if you want to roll your own or buy a premade unit.

Hello, I have  scratch built a large industrial complex for my layout. Included are 4 tall stacks. At the top of each stack are 3 amber wheat grain bulbs (12 total)

I want them to flash all at the same time. Some have recommended an automotive turn signal relay. I really don't want to go that route if I can avoid it.

Is there a solid state switching unit with input and output lugs that may exist to accomplish this?

I thought about using flashing wheat grain bulbs but 12 bulbs flashing independently will be annoying.

Thanks in advance. Nick

There is a project in the "Electronics Projects Developed on the OGR Forum by OGR Forum Members" in the sticky post Electrical Reference Materials in the upper part of this Electrical category.

Check out project #5 which shows a flip-flop circuit using mosfets to drive up to one amp of incandescent lights on two separate outputs. The standard values give about a 1 Hz flash rate. Maybe you could flash half the bulbs alternately with the other half? I know the guy who put this project in so let me know if I can help!
