Quote:The cutoff is totally a product of the lens and/or reflector. These bulbs should not produce a significantly different beam pattern from your original bulbs. What they will do is fill out that pattern more fully since the output is higher.
I received My Toshiba 9012 bulbs from Daniel Stern on Tuesday. have a hevy Avalanche and the stock low beams fall into the 'I can't believe it's legal to sell a vehicle with such bad headlights' category. I wasn't able to install them until today (Saturday) and I've just come back from adjusting them and taking them for a test drive on the freeway and the 'back twisties'. I am very pleased. The quantity and color of light is very good. The beam pattern has a good foreground 'spread', wide side-to-side' dispersion of the 'hot spot' and a very tightly contolled upper cutoff. I found I was able to run them about a degree higher (2 inches at 24 ft.) than the stock bulbs, without causing offence, because of the sharp cutoff...
Quote:Then I would suspect that the sharper cutoff (and the more even spread) is a result of correct filament placement in the new bulbs, against sloppily-made cheap 9006 bulbs. That's interesting, but maybe not surprising.
