Identify Date Code

[JustMeHere]

Can anyone tell me what is the date code on this bulb?

It's hard to read but I don't see anything that looks like a date code.

Images of other samples would suggest that the only unique markings are "22H725". That said, I can't see how to decode them.

Perhaps the "H7" part is the date code.
So August 1987 or 2007 based on this:

H7 could make sense.  It came from an 08 Acura.  Says alot for those bulbs if it is.  That also means the body shop that repaired that side of the car didn't get a new bulb like they should have.
