The best lighting for all weather is the stock headlights.
Your eyes cannot see the blue spectrum like they can see yellow, thats why most european cars have yellow headlights/foglights. And thats why the oem doesn't use blue bulbs. I've gone thru all of this in the past year. Went from stock to some super bright blue bulbs, then to silverstars, which are much better than blues, but in all actuality the stock replacement bulbs work the best in all weather. The silverstars seem brighter because they are a higher wattage.
