Bay Door "OPEN" Warning Light or Buzzer - hypoxia - 02-28-2025

Looking for ideas for making an open bay door warning.  Each door has a switch which turns that bay LED light on when opened.  What is the best way to send a warning to the driver?

You could wire in something like this with a switch to turn it off if your actively outside using the open bay.

You could also use wireless sensors. Something like this:

Wire all the lights into coil of relay, relay then goes to buzzer or light on/near the dash. Relay isolates things so it does not back-feed and turn on the rest of the lights. You would need a relay for each bay light to isolate them.

Reminds me I need to do something like this for my tv antenna, second time I left mine up and headed on down the road.

Good ideas.  There are 9 bay doors, 9 relays would work although I'm hoping for a simpler solution.  Wireless could work but it needs to be reliable and not baby sat.  The preferred indicator would be a dash light with or without a noise.
So far my Cargo Door Open alarm has been audio in the form of honking horns.
