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!
