Not to belabor the point, but the source I quoted before does sell "convex"
H4 (and H2) headlights that have the curved face.  The light pattern is
probably not quite as good, but I'm very happy with the ones I bought for my
Stag.

These are available from many makers, not just PIAA.  The bulbs I
recommended are equivalent.  Because the power is similar to stock, no
wiring upgrade is necessary.

But I still recommend an upgrade with relays for best lighting, since as
little as 1 volt drop in power to the bulb can reduce light output by as
much as 30%.

Although I didn't like the way they looked on the car (secretly glad they're
broken), the high-power "blue" Xenon bulbs I had on my TR3A were truly
impressive on dark roads at night.  Driving up US180 to the Grand Canyon at
2 AM with a new moon a few years back, it was simply amazing how much of the
road I could see.  Reflective signs were almost painfully bright and visible
(as dots) for over a mile.
