Firetrucks need help

[shokjok]

The simplest circuit would be a pulser connected to a flip-flop driving a pair of MOSFETs powering the headlights. This idea I am trying before I can upload the schematic, some of my 2B1 headlights work on high beam only and are suitable for this circuit. My circuit will use a 555, 4013 or 4027, and IRF630/ 640 MOSFETs.

this topic seems common. I did this solution for a guy on a different board a while ago

It's hard to build one for cheaper than this:
**broken link removed**
Includes enclosure and power switch.

I suppose if it is compatible.

If you really want to get their attention you need high intensity quick flashes that normal vehicle lamps are not capable of providing.

I can't find the site I was looking for but did find this one:

I was actually looking for one about the instant LED turn on in motorcycle brake lights making them safer by giving the driver behind them an extra 150mS to stop.
