There are alternatives to getting more light other than adding aux lights.
With some vehicles you can modify the headlights to have both the high and low beams come on at the same time.
You can also upgrade the bulbs. I installed Sylvania Silverstar bulbs (not the ultra) on my truck and it made a substantial difference. I also polished the lenses and adjusted the headlights to optimize the light.
I was having problems seeing at night and especially on remote highways where there's critters. I couldn't see far enough with just the low beams to feel comfortable going 75 miles an hour. Not any more though. Sylvania says that you'll see a ~ 30% increase in distance and that's about the improvement I noticed.
I replaced just the low beam bulbs. My high beams work very good but if I did more night driving I'd replace the high beams too.
If you choose to upgrade the bulbs go with something other than Sylvania. I did some research after I bought the Sylvania bulbs and found out they have a reputation for only lasting a year or two. Not good.
