About the brightness:
The driving lights just annoy other drivers, and they're useless unless you are on a completely unlit road.
Then they are unmatched by anything halogen powered. But on those roads you sorta wish you had 4 of them and they were hood monted ...if you know what I mean.
It is hilarious when a driver coming towards me flashes me because he thinks I have my brights on or somehting, and then I flash him my driving lights.
Awesome.
Its so bright you can see in the backseat of thier car!

Bet they feel stupid.
But seriously I only use them at night on unlit roads with no traffic. Otherwise it would be 1) a waste of money, 2) not very nice. There is a reason why HID conversion kits are now illegal.

P.S. Some good 'holy damn bright' music is in order of oomph:
Hail Brittania - don't know
Halleluyah - Mandel
Dies Irae - Motzart Requiem (the nightcrawler scene from X2)
Ode to Joy - Bethoven 9th last movement
P.P.S. Notice the microDE beam pattern is the same as HID without the higher right side. Its a halogen bulb in a xenon housing. And yes they make a xenon version.
