I went walmart and got a pair of 55w halogen lights for $14.88 and a 12volt 8 amp battery for $43, IT WORKS EXCELLENT. I also bought a 2amp automatic charger, so far I've used the lights for 30 minutes at a time with only 25 percent discharge. I can see very good with it , I decrease my speed to about twenty MPH for safety, I also use a planet blinky tailight, very highly rated. I feel as safe as daytime driving, as I am very visilble with this setup. As long as the battery is not discharged over 50 percent, it should hold up well. This sure beats spending 2 or 3 hundred bucks on those fancy systems you see out there!
