So I am on the edge about changing out my headlights.

First of all I would be doing it in stages. First I would get the projectors, then at some point in the future I would install HIDs (or LEDs maybe?). So for awhile I will have just ExtremeVisions in there.

I'm leaning towards the projector retrofit into the OEM headlights (and the clear corners), but here are my concerns:

1) Can I find them anywhere, or will I be on my own to make them?
2) If I find a set, how likely are they to be faded or start to fade soon after? My vehicle has been garage kept for pretty much its entire life until recently and the UV coating is already starting to fail on the factory lights.
3) I hear the clear corners on eBay leak?

If I go with the one piece heads and sides available on the web:

1) I hear light output is crap compared to stock without HIDs? Since I would not be getting HIDs for a little while this could suck...
2) It looks like I'll have to wire some stuff. I fear ****ty GM wiring issues (previous experiences) if I start to disturb stuff. I'm okay with HIDs, but all the supplemental stuff scares me. Lol.
3) Will these fade or leak? This would be the only thing that may make me lean this way. Trying to think for longevity as well. I'm driving this until it dies and it's only at 55k miles.

Alternately I could just get the clear corners and leave the halogens in...

Any thoughts?
