I need a recommendation for an indicator light (maybe mailorder?) for my
mailbox.

Here's the situation.
* It's a custom mailbox, basically a door cemented in a pillar of concrete
* It just has a square metal door with a brass inside latch (all metal)
* It's higher than my eyes in the car window by about a foot
* So I have to reach inside to see if anything is in there
* It doesn't even have one of those little red (manual) flags
* There isn't 120v lighting but landscape lighting is only a foot away

I wonder if technology can help me?

It would be nice if there was a way to mount an external LED such that an
internal light sensor activates it to indicate mail in the mailbox.

Any pointers?

Here is one of them. They have been making all types for at least 20 years.
