Eurolight Identification and source

[Ben Swann]

As I need to replace several bulbs that have burned out in a couple 200Qs with
Eurolights, I am trying to identify a proper replacement and source for them.  The bulb
I removed had the low beam portion burned out.  It is a three prong halogen bulb and
markings on it are:

12V (of course)  100/90W U  HD  not for use in Europe

There is no manufacturer identification on this bulb.

I have been happy with this bulb, and don't know what is in the other lights, but they
all have the same three prong configuration.  All the E-lights I have are relayed and so
can handle the wattage and since they turn night into day, probably don't need more, but
open to suggestions.  Mainly is this an off the shelf item, or something I should order.
To tell the truth, I don't pretend to know anything about the different bulbs, so open
to comments and suggestions on the best replacement.  Quality is good, but don't ant to
pay too much either.

The lights are similar if not the same as the ones shown In this thread:
