Well, the first thing to do would be to make sure the headlamps are in brand-new condition -- which they probably are not, being 14 years old. Polishing won't do it, and the aftermarket headlamps are all garbage (except for the "Xesighting" halogen or HID units that were made by Valeo-Sylvania, but you'd have to look hard to find a set now). The stock headlamps are cheap and minimal, so you can't increase the intensity of the low beams much without producing dangerous glare levels. Use
Philips Xtreme 9006 bulbs in the low beams. You can do more with the high beams; put in
9011 bulbs (you'll have to trim one of the base tabs).
Get rid of the Silverstar junk in the Toyota; if you're not upgrading to good replaceable-bulb headlamps then put in a set of
GE Night Hawks, which are
way better than the Sylvanias.
