Simple on and off switch to toggle between two circuit (headlight high or low)

Question

to start off, honestly I just know simple circuits that's why I went on asking in this forum,

So basically I have a driving light that has two modes, high and low. It consists 3 wires. A black (gnd), red (low light), yellow (high light) wires. So this can be toggled if I used a 3 way switch. But I wanted to use a simple on and off switch to toggle between high and low beam. Is there a readily made circuit that I could use? Or can anybody point me to the right keywords on what to search?

So basically it goes like this:

• Off switch : Off lights
• On switch: High light
• Off switch: Off light
• On switch: Low light
• Off switch : Off lights
• On switch: High light
• Off switch: Off light
• On switch: Low light

Answer 1

If we use a timing diagram to describe your requirements it becomes a lot clearer.

Switch    ____|    |____|    |____|    |____|    |____|    |_____
               ____                ____                ____
High beam ____|    |______________|    |______________|    |_____

A bi-stable latching relay would be a simple solution.

Figure 3. Go to HomoFaciens and click "Start animation" to see how the pawl mechanism is advanced on every impulse of the relay coil.

The relay shown in Figure 3 will be a low current device so typically we would use that to drive a heavier duty relay to control the lights. I have not shown the additional relay in Figure 2.

If this circuit is for a car it seems like a very poor idea as the lights will go off during every transition from low to high and back again.

Answer 2

It can be build with 4017 IC connected as ring counter with 4 states, at 5th state reset to 1st. The off outputs dont have to be connected. If your wires are power lines (not just logic sig.) you must insert transistor/relays to outputs.
