I put Sylvania H6054ST Silveerstar lamps on one of my cars a couple of years ago. Wow! a lot more light, especially close-in in front where it blinded me from seeing at longer distances. There is, however, a fine spread of light off to the sides for seeing those deer you guys are so worried about - perhaps the best I've had with sealed beam headlights.
After a couple weeks of the near hotspot blinding me and other drivers flashing me for blinding them, I did some serious inquiry into how to adjust these monsters. And found I've always been doing it wrong.
I used a screen of some old drywall set out front so I could see the light pattern, car center line extended from measured centers of windshield and rear window and marked, headlight centers laid out on screen as 1/2 their distance apart from car center line and height projected with a laser level from lamp centers. The car was on a level garage floor.
Best lighting result is with the vertical adjusted so the low-beam top cut-off is horizontal (on the lamp center-line), and the horizontal set so the high-beam hot-spot is centered straight ahead. These reference points were poorly defined on the Silverstars.
This gives good low beam coverage, eliminates the near hot-spot, and puts most of the high-beam light up in the air, where it will illuminate an upcoming hill. I hate compromises...
However, these lights put an awful lot of low-beam light into the oncoming driver's eyes. I expected much more when I saw Osram's name on the box.
If they haven't changed their pattern,I'd say Silverstars kinda suck. Expensively.
The same aiming proceedure applied to the GE ordinary halogen lights in my other car gave excellent results, good coverage both high and low beams, virtually no glare to oncoming driver, a pleasant surprise. Seems there are no properly-aimed lights out there? Every oncoming car is an unpleasant, blinding experience, and testing of mine (the standard halogens) yielded no complaints.
Somewhere there must be some really good headlights, but they aren't these. Best I ever saw were in a BMW quad-light set-up, regular lamps in the high-and-low, flame-throwers for the high-only. Miles of light! Could really use that out here - our roads just go on forever.
