What follows is a review of the projector headlight conversion that you see all over Ebay.
I saw somebody else on the forum make this conversion and I had lots of questions. So I decided to buy some myself to satisfy my curiosity.
I want better lighting. Who doesn't?
Plus, let's be honest, sealed beam headlights aren't going to be around forever, so the conversion makes sense and may be inevitable.
That, and the projecttion headlight on my 2006 Xterra and 2004 minivan are superb - especially compared to the sealed beams on the Fiero.
The kit that I found is inexpensive - about a $30 investment, including the shipping. Not a bad deal. I figured it was a no-brainer since they were so affordable.
After about a week, they arrived as a pair with the new bulbs installed.
The black housing is made of tough plastic or aluminum (can't quite tell) and the front is made of glass - an important consideration since projector bulbs run much hotter.
They came with new connectors - something you MUST install since they are rated to handle the hotter temperatures that will melt the stock connectors.
Inside the glass is also a blue-tinted bulb that is supposed to be a "city light". These little bulbs have their own wiring and I can only assume they are meant to add color to the light beams and/or provide a cool look when the main lights are turned off. Either way, they seemed "ricey" (read: stupid and not needed) and are a moot point on a car with pop-up headlights. I didn't wire these silly things up.


After installing one of the lights, I took the car out for some comparison photography. It had just rained, so it was a little hard to see the lights on the street. But as you can see, there are distinct differences that stand out immediately.
Firstly, the projector bulbs are brighter - as you can see in these photos. BUT, that doesn't mean that you can see better with them, as I will explain in a second.


Notice in the second photo how, towards the bottom of the photo, the road is not covered in light by the projector bulb as much as the sealed beam.
That's because of the lousy light pattern these things throw.
This is better demonstrated in this photo:

Notice, in particular, the grass on either side of the pavement. The sealed beam shows much better detail and covers more distance - hands down.
Also notice the lousy light pattern the projector bulbs put out. It is all over the place. (!)
The high-beams are even worse. When activated, they put out less light than the "regular" mode. Believe it or not, it is far easier to see without the high-beams on.
CONCLUSION
Personally, I don't care for them. They look cool on the car and they give off a different light that makes the car stand out, but it is not a "better" light.
Most importantly, they don't increase visibility at all as far as I can tell. I will drive with them for a few weeks and see if I end up getting used to them, but I highly doubt it.
I am even considering putting better projector bulbs in there since I am sure these are cheap ones, but I don't expect that to solve the lousy light pattern they throw since that is mainly dictated by the reflector, not the bulb.
All in all, I think I may just reinstall the sealed beams.
