Poor headlights have always been a problem on v-dubs, not helped by the now-dated light units, and the fact that power to them is via the same relatively small cable that supplies everything else. Its definately a two-pronged approach (new units and better supply) but unfortunately many just assume fitting brighter bulbs is the cure. Nightbreaker bulbs are good, but I think the correct order of headlight upgrades should be:
1. Fatter cable from battery to dash
2. Replace lens-based Hella units with modern reflector-based ones (brighter & better beam pattern)
3. Install relays
4. Fit Nightbreaker or similar bulbs - but only if needed. (1,2, and 3 was enough for me)
Having tried it, number 4 on its own made nowhere near as much improvement as the first three combined. Brighter bulbs just aren't needed unless you have square lights and are effectively stuck with old technology.
