Thank you very much. Did a Google search for acrylic lens and that site
didn't pop up.
They are exactly what I needed and at a price I can afford.

Thanks again.

You're screwing yourself if you put in Sylvania Silverstars or other
bulbs like them. They produce *less* light, not more, and the light is
*bluer*, not "whiter".

Here's manufacturer data, from internal engineering databases, for
output
and lifespan at 13.2v for H1 bulbs. The numbers here are a composite of
values applicable to the products of the big three makers
(Osram-Sylvania,
Philips-Narva, Tungsram-GE). Each manufacturer's product in each
category
is slightly different but not significantly so.  I picked H1-type bulbs
for this comparison, and while the absolute numbers differ with
different
bulb types (9006, H7, H3, etc.), the relative comparison patterns hold
good for whatever bulb
type you consider.  Lifespan is given as Tc, the hour figure at which
63.2
percent of the bulbs have failed.

H1 (regular normal):
1550 lumens, 650 hours

Long Life (or "HalogenPlus+")
1460 lumens, 1200 hours

Plus-30 High Efficacy (Osram Super, Sylvania Xtravision, Narva
Rangepower,
Candlepower Bright Light, Tungsram High Output, Philips Premium):
1700 lumens, 350 hours

Plus-50 Ultra High Efficacy (Philips VisionPlus, Osram Silverstar,
Narva
Rangepower+50, Tungsram Megalicht, but not Sylvania Silverstar):
1750 lumens, 350 hours

Blue coated 'extra white' (Osram CoolBlue, Narva Rangepower Blue,
Philips
BlueVision, Tungsram Super Blue or EuroBlue, Sylvania Silverstar):
1380 lumens, 250 hours

Now, looking over these results, which one would you rather:

(a) Buy and drive with?
(b) Sell?

The answer to (a) depends on how well you want to see versus how often
to
change the bulb. If you want the best possible seeing, you pick the
Plus-50. If you don't care as long as it works and you don't want to
hassle with it, you pick the long life.

The answer to (b) is determined by how rich your company's shareholders
want you to be, and is obvious: You want to sell the bulb with the
shortest lifespan, highest promotability and highest price. That'd be
the
blue unit, e.g. Sylvania Silverstar.

I know we have been through this a million times, but...

You do not want white (or bluish) color lighting for foglights
especially.  There is more scatter of the shorter wavelengths which
results in poorer viability in bad weather.  That's when you use fog
lights, right?

If you want top make a fashion statement and also prove that you are
more intelligent that the ricers, get *yellow* bulbs for your fogs.  ;-)
