These are more expensive,

but I've seen a car with a similar setup as these:
and they looked cheap (Nissan Altima '05).

Which would look better, and how hard is it to open the headlights and reseal them to ensure they won't fog up?

 

I heard once you open your headlights the seal will never be the same and can cause condensation on the inside of your headlights.

 

You can always just buy aftermarket headlights with halo rings on the headlights already and not worry about install them...

 

aftermarket headlights r alll GAH-BAGE

 

you can reseal them just fine. Take a bead of clear silicone and run it around the original seal.

The first time I did my head lights i reused the original seal and they had a very minor leak. Second time i did the silicone trick i just said and no more leaking ever!

 

^ yeah just seal it throughly and you're fine, I've done mine and have 0 problems.

 

All aftermarket headlights leak or have condensation after awhile. You can easily reseal stocks

 

Yeah, I heard the aftermarket ones all suck... so which would you guys recommend putting in my headlights/is there a guide out there for the wiring, or do you just hook them up to the battery?

 

jus go with the oznium rings, i have the green ones but am switching to the whites and i wired mine to be my parking lights but you could also hook them up to a switch and that is what i think im doin next. http://img.scionlane.com/photos/10/9...874e098f69.jpg have never had any problems with moisture or condensation.
