12v LEDs

I think you can buy LEDs rated for 12v out of the box but another alternative is these. They are prewired and have a built in resistor and are relatively cheap.

 

I don’t have a specific use... yet.

 

Pack of 50 in different colors were about $8.

I used something like that, one on each relay 87 contact to chassis, this was a great troubleshooting aid.

You soon get used to the light show and immediately recognize when something is amiss.

Mount them by drilling a hole in the relay base although you could also mount them on a little plate beside the relays.

Just pop each 87 contact out and solder the small wire to it.
