This is a modification, but not an upgrade.

Properly aiming your H4s is step one, and the most important step.

If you're trying to get the most out of your H4 setup, get a pair of these 60/55W Tungsram +120 bulbs from Daniel Stern Lighting.

If you're using sugar scoops and want to maintain a period-correct look, Stern can also get you Koito euro H4 7" lamps which are the best halogen lamp money can buy.

If you care more about night-time vision, the JW Speaker 7" LED lamp is the best on the market, but it just plain looks wrong on a 911 (and has to be used with Sugar Scoops or Audette style.
