Hi, currently working on a simple circuit to turn on/off flashers on a car using a solid-state relay and PWM from a mcu. Can anyone verify my circuit diagram, not sure how to use the solid-state relay yet.
See attached screenshot:

 

hi Linus,
Welcome to AAC.
Do you have datasheet for the G3VM you could post.?

Yes ofc, my bad!

currently working on a simple circuit to turn on/off flashers on a car using a solid-state relay and PWM from a mcu.

Why PWM?
Do you want to be able to dim the lights?

No need to dim, but want to flash them 90 +- 30 times/min

To do that won't you need to bypass the existing flasher module? Don't know about the cars with a BCM, but the old ones only had one flasher that was then controlled by the turn signal switch, both turning the flasher on and directing it left or right. Today's cars, I think, have the flasher in the BCM(body control module).

Don't they already do that? I believe 60-120 flashes per min is the legal range under UK vehicle lighting regulations. Don't know about other countries' regs.
