Light built into car keyless entry?

[deKatt]

I got a freebie at a conference that is a cheap led light and a whistle, attached to a key ring. It's about the size and shape of the keyless entry remote that's already on my key ring, and that got me to thinking (a rare, and often dangerous thing): do any car manufacturers include an led light as a function of the remote?

We once had a '91 Subaru that had a green LED built into the key. Pretty unusual at that time.
