My 4x4 is a tow pony so sealed beam isn't needed.
Had H4 Hella,and was not happy.
I Now run those clear reflector lens available on ebay for as little as $30pr+ postage.
Probably a 20% increase in light output with the defuser.
Remove the defuser inside lens + approx 30% more light again.
Its a little tricky to get defuser out, you have to crush/cut it abit to fit it out threw hole, and not scratch inside lens.
Think they/these ones, may not be legal due to focus is wider than std, but I work on the Rd for a living at night and I can't tell em apart from other late mod cars out there.
You may just need to install a globe that has the tip painted to remedy removing defuser in the lens to keep this part legal, some old rule about how looking directly at the light blinds people or some cr#p.
Personally think lighting has moved way beyond this but thems the rules.
Recon for the price it's worth given them a go.
See if ya can seal em up , if successful you won't go back.
And with a globe up-grade +50, 5500k-6000k.
Iv'e had these for a yr now, think +20 and 5500k and only last week I still told my missus how impressed I am with the setup again
