Smoked headlights will decrease your light output even more, the marauder headlights are not just smoked, they actually have a different design which allows for dark surrounds with no loss in light out put.\

You best bet is to get a set of Sylvania Xtra Visions (they have as much light output at the silverstars and at a longer expected life, and they are half the price) also if you upgrade the headlight wiring to 12 ga. with heavy duty relays, it will reduce the amount of voltage loss. It is not uncommon for our headlights to see under 12v at the socket, if you can increase that voltage to just 13V you have added nearly 10% more power.
