internet search I get nuttin'
The best 9004 and 9007 bulbs presently on the market are ultra high
luminance items _without_ any blue tint on the bulb glass. They're an
uncatalogued item made by Osram-Sylvania/Vosla, considerably better for
intensity and beam focus than any of the parts store items. These are
$25.45/ea, and I have them in stock.
I can find them too , But why doesnt Philips show/list them on their web site
Stern recommends you buy bulbs from him because he has " "the secret stash" unavailable to the public Sylvania bulbs"
Here is his email quote to me :
Oh WowWhat ever that means LOL!
