Thread: 12V Circuit Up based on Hazard flashers

I hope this isn't too elementary for this group, but I have need for very simple a 12V automotive circuit that will light a lamp continuously based on the vehicles' hazard flashers being on. (Background: the tail lights on an equipment trailer are hidden when the gate is open. Have added some LED strobes that can be seen by oncoming traffic, but they need a continuous 12V power source. I would like for them power up whenever the (intermittent power) to the "hazards" is active.) Any suggestions? Thanks!

Thanks for the replies.

I should have pointed out that this needs to be self-contained within the trailer, so intercepting the hazard circuit before the flasher would work, but would require an non-standard additional wire to the trailer (which needs to be standard so it will function the same way no matter the tow vehicle).

The strobes currently get their power from the "tail lights" through a manual switch. I can intercept the intermittent power from the "hazards" when they are on so it would be nice to either: 1) actually provide the power to the strobes, or 2), keep a relay closed so I can power them from the continuous "tail light" source.

This would help prevent the idiot driver (me) from forgetting to turn off the strobes while tooling down the street.

The diode/capacitor might just do the trick, but would I have to be concerned that it might continue to power them for some time after the flashers were turned off - or is that just a function of proper sizing?

i am a student want to know the flasher relay circuit and hazard circuit for automobiles thanks and more power
