In the near future, I will be purchasing a few lights. I know exactly what I want, I'm getting "Lightforce" lights. Two 170 Strikers for my brush guard and four 140 Lance's for my roof light bar.
If they're good enough for Rod Hall's "Team Hummer", they're good enough for me. Plus they look cool and they're light (no pun intended).
