I really don't know why they're not made to fit in the low beams. They're so much better.

I had 2 major worries before doing this:
1) Power. I was worried about the wiring. Then I realized that these bulbs only draw 60W compared to 50W for the 9006.
2) On-coming traffic. I was worried that I would blind everyone. Well, I adjusted my lights, and they're set perfectly. Not a single flash from an on-coming driver.
I figured for $20, it was worth a shot.

If I were you, i'd give it a shot. If you don't like the results, just put the 9006 bulbs back in.
