I've done some looking into this, and there are several bulbs on the market that will do the trick.
Basically you're looking for a 5-6K bulb (anything higher is blue, like your driving LED's) if you want to match. You can get "performance" bulbs if you like (read: bulbs that with overpowered filament that wears out faster) because they're high beams and not used often.
Its very very difficult to find actual legitimate information on bulbs. If I may speak frankly, it's because a lot of idiots spend big bucks on bulbs, and meaningless adjectives have become the selling tools instead of Lumens, Color temperature, Lifespan, Beam angle and Wattage.
So when I look at a maunfacturer's choices, I am faced with such crap as "Super White" "Ultra White", "Cool White", "Centra Silver Plus Super", Ultra Plasma" and so much more obfuscating trash.
I would like to do a thorough comparison of the top few bulbs, but that would mean finding a retailer with good returns.
Regardless, I'll post back tomorrow with my Top-5 list that I've narrowed down
