Always been confused about adding these lights... are these considered "headlights" or "indicators"?

I'm curious on how to add these lights... or more specifically how to make them light up. I have red ones I need to add on the rear bumper to be lit up while the engine is running. And I have amber (yellow) ones I need to add on the front top of the cab for the same reason.

I know how to add flashing lights as it's essentially cutting and pasting with ELS lights. But these lights are a little different. They aren't necessarily ELS. They need to stay on all the time while the engine is running.

Any suggestions?
