I tried that but only the flashlight bulb flashes. I can't make the added lights to flash.

 

[KJV]

Flashlight has one led bulb. Head light has 7 led bulbs. Power goes to flashlight circuit board which is in flash mode but everywhere I try to get power from it just makes the head light come on
No flashy flash.

 

[KJV]

You're deali ing with LED.
: you're on your own. I only deal with the old school bulbs and lites.

Ithe seven bulbs are most likely all on one board making it one bulb so if you disconnect the one bulb and connect the seven bulb board to the with the one bulb it should work as a controler.

They sell trigger strobe modules that can be soldered in. Fairly cheap. Might be worth a shot.
