I have Sylvania Blue Headlights in my 66
They didnt have the white ones in stock.
You can't even tell these are blue however.
Unless you get up close and you can see a bit of a blue tint
I like these, very nice driving lights and beat the crap out of sealed beams

I wouldn't hate 'em if they were any good....like paying $40 for Silverstars when you can find an other blue garbage for $8/per, last time I checked.
Just to pile on, I'll let this gem in for good laughs. Not pimping any pages, but that Daniel Stern guy on Google is good:

No, they don't. Let's take a look at what they're saying and what they're
not saying:
]Whitest. Brightest. Sharpest.
1) The color of the light ("whitest") has no linked relationship to how
well the headlamp performs, or how well you can see with the light
produced by it.
2) "Brightness" is like "Loudness". It's a subjective perception. Is
Metallica "louder" than Bach? Most people would say so. That's why
audiologists use an objective measurement, Sound Pressure Level, rather
than subjective quantities like "volume" and "loudness". And so it is in
the science of light. "Bright" and "Dim" are subjective perceptions.
Intensity, measured in any of several precisely-defined and scientific
ways, is the only real way to gauge or compare output of a light source or
performance of a lamp equipped with a light source.
3) "Sharpest". Translation "Look, kids, this bulb is super chinpokomon
kewl!"
]Now there's a new star on the road, burning brighter and whiter than
]halogen ever has. SilverStar illuminates with a searing intensity,
]exceeded only by far more expensive High Intensity Discharge lighting.
]SilverStar is fueled by advanced design and backed by the prestigious
]SYLVANIA brand with its longstanding commitment to halogen innovation.
"Brighter and whiter" we've already handled, above.
"Intensity"...Oooh, those wascawwy wabbits! They used a scientific term,
but without any quantification. "Searing" doesn't count.
"Exceeded only by...High Intensity Discharge"...The color of the light is
bluer. The degree to which it is blue is exceeded, in legally-compliant
headlamps, only by HID headlamps. Color temperature has NOTHING to do with
a headlamp's performance or your ability to see by it.
"fuelled by advanced design"...nothing of the sort. They drive the snot
out of the filament, running it right at the bleeding edge of maximum
allowable current draw to get enough light to be legal passing through the
light-stealing blue filter. Bulb life is extremely short and light output
is not near the high end of the legal range.
And irridescent surface reflections off of the colored coating on
these particular bulbs does as such reflections always do: throw light
where it's not supposed to be.
Given 2 same-format bulbs of equal build and materials quality and equal
wattage(apples to apples), there is *ALWAYS* a performance DISadvantage to
colored-glass bulbs. Always. This is simple physics; there is no such
thing as a filter that adds light. They *ALL* subtract it. Given any
blue-coated bulb, that same bulb can immediately be made to produce more
light by removing the coating.
The Xtravision bulb produces more light. Period. No "White searing super
hot ultra cool" marketing bull****, no short bulb life, no extra
filament reflections, no light-stealing filter...just more light.
It's really that simple.
Bulbs have a nominal wattage rating and a nominal luminous output. And --
pay attention, this is the important part -- there is a tolerance of
typically plus-or-minus 15 percent for both of these values. Some bulbs
have slightly smaller tolerance ranges for one or both of these values,
but 15% is standard. Get that: Fifteen percent allowance on EACH SIDE of
the nominal value. That means an allowable performance variance of THIRTY
percent.
Take a hypothetical bulb with nominal ratings of 1000 lumens and 55 Watts.
The tolerance means it can legally consume between 47 and 63 Watts
(rounded), and can legally produce between 850 and 1150 lumens. You
probably don't care whether the bulb consumes 47 or 63 Watts, but if you
have two brain cells in your head, you damn well should care whether your
bulb produces 850, 1000 or 1150 lumens. And if you're offered the choice
of a bulb that produces 1000 lumens, a bulb that produces 1150, or a bulb
that produces 850, you could make a case for buying the 1000-lumen bulb,
but you're stupid-stupid-stupid if you buy the 850-lumen item. Now add
the fact that the 850-lumen bulb costs $22, the 1150-lumen bulb costs $8
and the 1000-lumen bulb costs $5. Shall we add another couple "stupids" to
the three you've already got if you pick the low-performance bulb?
Want more? Here's a test of some blue-coated bulbs vs. some clear ones:

DS, tired of explaining what should be utterly commonsensical to anyone
with two eyes and two brain cells...

HID's are fine. Meeting one is only slightly worse than a regular car. Driving a car with HID's is awesome.
Blue lights on the other hand are freaking stupid. All they do is blind the oncoming traffic and they don't help you see. I wish this law was enforced better.
