Thread: metal lightbulb shield inside light housing? is it needed or not

Thats unpossible.

How can there be more light on the road... if the lightbulbs aren't brighter than "stock headlights"?

Sorry to say, but HID's are stock on a lot of nicer cars these days, and the SUV's with them on are MUCH more blinding than the standard halogen headlight SUV's.

I say SUV's because those are the only ones with their headlights high enough to blind even if their high beams are off and their headlights are aligned properly.

HID headlamp burners produce between 2,800 and 3,500 lumens from between 35 and 38 watts of electrical power, while halogen filament headlamp bulbs produce between 700 and 2,100 lumens from between 40 and 72 watts at 12.8 V.

From Wiki but i'm sure Sylvania would produce similar numbers.
