Not cool. Do you figure it is the bulb or the ballast?

That's a horrible pattern for low beams. My projectors, because of the internal mask behind the lens, throws a nice, wide, flat beam with a very sharp horizontal cut off that is stepped up so that they throw out further along the shoulder/ditch and dip lower in the oncoming lane. Properly adjusted, even with 50W HID lamps, I can see out about 300' without annoying oncoming traffic. Are you sure your HID lamps are properly seated in the headlight housings, so the capsule is in the focal point of the reflector? I'll have to scrounge up a digital camera and post some photos of the beam spreads seen from the driver's seat at night, and some frontal shots of the installed lights.
OK, this is not the vendor I got them from, it took a lot of scrolling through "98 Silverado projector headlights" to find ones that looked the same as mine, but these are it. I have them sitting over a set of black LED marker/turn lamps in a black grille. Looks pretty good on a white with black flares/trim/running boards 'Burb.

The HID kits I retrofitted in (some modification was necessary on the H1 projectors for the HID lamps to fit in and lock in place) were 50% off on a sale by a reputable eBay vendor.
I did not have to silicone the edges of the lenses to waterproof them, I've had NO fogging or leakage in two years with mine. The mounting bases were a good grade of fiber-reinforced nylon, not cheap, thin recycled milk jug plastic. I can't speak for these, but they LOOK identical to the ones on my Burb.
See my comments above about quality of the Chinese replacements. Most (not all, but most) of the eBay vendors out in California are sourcing their stuff from China by the cargo container load. They all are within a few dollars of each other in price, and lots of times offer "bundle" packages of headlights, turns and marker light combos ridiculously cheap. The first set that I ordered were Euro-style multi-reflector similar to what you posted. I returned them because of their poor quality. The biggest three problems with them (and the other set I bought before I found my true projector set) were:
1) The base plate that bolts to the radiator support, while looking similar to the factory OEM part, is not of the same quality. Instead of being made of fiber-reinforced, thick, very rigid nylon like the OEM (almost like Bakelite), the CKO backing pieces were thinner and made from polyethylene (recycled milk jugs) and flexed when the adjusters to aim the light assemblies were used, so that the lights didn't move, the backing plate did. Also, while looking similar, and the four mounting bolt slots pretty much lined up with the radiator support backing nuts, the base plate did not fit flush to the radiator support's contours like OEM, thus the base plate also flexed when bolting it to the radiator support, so the horizontal and vertical adjusting screws didn't quite line up with holes in the lip of the radiator support. Additionally, the lead screw for the vertical adjustment that came out of the back of the base plate didn't line up with the hole it's supposed to go through in the radiator support, causing interference and making the headlight sit cock-eyed in the grill opening (very similar to what was described above in post # 25). The CKO design on both sets were such that you couldn't interchange the base plates with the OEM ones so you could use the new lights with the old bases. The adjuster assemblies and light mountings, and how they mounted, were totally different than the OEM and not interchangeable or adaptable.
2) Reflector quality. As I stated above, I found the quality of the reflector casting/plating to be really bad. Ripples, drips, waves and "foggy" areas with incomplete/"pebbly" nickel plating over the plastic injection molded reflector assembly. While these small imperfections may seem minor, ask NASA what a small aberration in a reflector did to the focusing ability of the Hubble Space Telescope. Same thing with headlights. Those imperfections are amplified as the light leaves the lamp and spreads out to cause problems with the light pattern and create "bright" and "dim" areas in the beam, diffuse scattering of the beam (which would do things like throw light into oncoming drivers' eyes or light tree tops alongside the road on low beams). Then there's the issue of the lens not being completely sealed to the reflector allowing moisture into the assembly. Shouldn't happen, ever. That's just cheap assembly practices/materials. There's a reason why Hella lights and KC HiLites are so expensive: Precision design and exacting manufacturing of their reflectors for precise beam pattern isn't cheap. There's a reason why you get a package deal on eight pieces, including shipping, for $95 on eBay: They aren't costing the dealer crap to get per piece, and they STILL make a profit eating the shipping cost. You get what you pay for is still true to this day.
3) Lamp mounting. Look at how the bulb inserts and locks into place on the OEM housing. It's a nice, precision cam mounting that pulls the bulb base in tight and holds it in place. The first brand headlight I got, had a ring that screwed on over the opening in the back of the lamp that the bulb inserted through then twisted to engage the three lugs on the bulb base. Only problem was that the bulb was slightly loose in there and would move around. It would have taken some serious filing/modifications to either/or the ring or back of the light to get the thing to clamp the bulb base tight. The second headlight set I bought was even chintzier. It merely had three small button head sheet metal screws screwed into the back of the lamp opening for the three bulb base tabs to engage to hold the bulb in place. The only problem was that the heads of the screws didn't extend far enough past the edge of the opening to engage the rim of the bulb base - once "locked" into place the bulb could still fall out of the back of the housing, and did! Three very small washers under the screw heads solved that problem, I thought, until I tried it and found that the depth of the flange the bulb inserted into was taller than the base and the bulb still wiggled around. I wound up bending the edge of the washers so they would clamp down on the bulb base when the screws were bottomed out. That set also gave me unsatisfactory beam patterns, so I wound up going with the true projectors and am very happy with them.
Caveat emptor: Buyer beware. You get what you pay for. That being said, I'm not saying everything off eBay is junk, but you need to shop carefully, ask questions and compare images, be wary if they don't show multiple angles of the product in the photos (like the bulb mounting ring) and carefully read descriptions from vendor to vendor as often different vendors are getting their product from the same source and use the same stock photos and description.
Have either of you considered using a good headlight haze remover/polishing kit to get rid of and prevent the yellowing of OEM lenses that is so common and then going with either a 35W or 50W HID conversion kit with the stock housings?
I ended up buying these. The seller happens to be located in Hacienda Heights, which is about 8 miles from me. I inquired if I could walk in to inspect and purchase and they declined. Not a good sign. However, I needed them so I ordered. They are actually better than the original ones you recommended here. Better in the sense that you do not need to make any modifications to get them to seat flush with the grill. They sit flush right out of the box. They do not have the nylon nuts the screws go into. I did place a bead of silicon all the way around the housing. It was apparent that the corners would be a likely spot to leak. The adjusters cannot be worked with a Philips Head screwdriver, only a tiny socket which I'll have to find. Otherwise, same level of construction as the prior, but without the modification headache.

Then, a MONTH after you bought your Chinese junk, dka99burb asked how they worked out. I was just letting dka99burb know my experience with dealing with those West Coast eBay Chinese bulk buyers after I checked his links, and the quality issues I ran into, since he asked. If you're unhappy with the purchase you made off eBay Big T, it's NOT my problem, it's YOURS, don't blame me, I didn't make that purchase, YOU did. Deal with the results yourself. Fix them or toss them out and start over. Not my problem.
How about LMC trucks's? Are they cheapos marked up or are they glass lense/higher quality?
