Silver 2k2 was kind enough to provide a number of links for headlamp suppliers in another thread. One was for "Daniel Stern Lighting" at:
http://www.danielsternlighting.com/home.html
I found his site particularly educational and informative. I E-mailed him regarding brighter high beams for my F50 (2005 Q45).
Here is his response:

Replace the existing 9005 bulbs with 9011. The new bulbs are not sometinted or overwattage version of 9005, but rather employ a relatively newtechnology called HIR, Halogen Infrared. The mechanical dimensions of thebulb are all virtually identical to the 9005, but the bulb glass isspherical instead of tubular, with the sphere centered around thefilament. There is a "Durable IR Reflective" coating on the sphericalglass. Infrared = heat, so the coating causes heat to be reflected back tothe filament at the center of the sphere. This causes the filament tobecome much hotter (producing more light) than it can by passingelectricity through it, *without* the shorter life or greater heatproduction that comes with overwattage bulbs (to say nothing ofoverwattage bulbs' incompatibility with stock wiring.)
Here's the comparison:
stock: 9005, 12.8V, 65W, 1700 lumens, 320 hourscompare: 9005+50, 12.8V, 55W, 1830 lumens, 175 hoursnew: HIR1, 12.8V, 65W, 2530 lumens, 320 hours
These bulbs are spendy - $27/ea - but their cost is worth considering incontext: Any number of companies will charge you more than this for atarted-up 9005 with blue colored glass (PIAA and Sylvania Silverstar cometo mind) that doesn't produce more light and has a very short lifespan.
The HIR bulbs have a double-wide top ear on the plastic bulb base, this isto comply with the law requiring different bulbs to have different bases.The extra-wide plastic top ear is easily trimmed or filed to make the bulbfit your headlamp's bulb receptacle. Once that's done, they go directlyinto the headlamp, and the existing sockets snap on.
Parking lamps and front sidemarkers can be made 60% brighter for greater conspicuity and safety for $3.98/bulb (type 2886x)
Shipping will be approximately $6.
There is also a zero-dollar easy modification you can make to the frontsidemarker light wiring so that the front sidemarker lights also act asside turn signal flashers, seehttp://www.danielsternlighting....html Thisis a LARGE safety improvement, as your turn signals become visiblelaterally instead of just front- or rear-on!

I intend to buy these lamps from him, and will pay my dealer to install them, even though $130 per side is a little pricey. It's a lousy job, and I don't want to spend an entire afternoon trying to get all the involved components aligned correctly after dismantling the related front body components.
I hope this helps anyone else that wants to improve the lighting on their F50, as I believe that most of the other suppliers only want to sell stuff that may or may not be truly effective. There's a lot of misleading info on lights on the 'net, and many sellers who don't really understand the basics of lighting.
Note, I have no connection with DSL except as a prospective customer, but I have learned over many years to be able to read between the lines, and to know when someone knows his stuff or not. I think this guy does.
