The problem with the halos, at least that I've seen is that they die unexpectantly. I've got two friends, one with a 99 Civic EX and one with a 93 Civic Si, both have black housed, dual halo headlights from a company (it's what's stamped on the headlamp) called Sonar.

There's nothing worse than seeing one working halo on the left side, and two working halo's on the right. lol.

I should note, they were all correctly wired -- they even made harnesses, these kids don't f-around, y'know?
