Has anyone used an aftermarket headlight ASSEMBLY replacement? And lived to tell the

Switched the headlight ballast back in 2016. At first the driver's side headlight would go out. After switching the ballast, then the passenger side started to go out.

I suppose this is indicative of the ballast being bad. However, it's an old car (2001 330ci) and:

a) both ballasts looked like they were in crappy shape, what with all the wear and tear over the years,
b) of course, people here know that a new ballast is exorbitantly expensive, so financially it doesn't make sense to buy oem ballasts,
c) buying a used ballast is iffy because...it could have a short life,
d) the headlight assemblies (both) are in pretty crappy shape too - gaskets all dry-rotted, plastic tabs broken off, lenses fogged up (i refinished the outer lenses using sandpaper and clear coat, which made them better, but the INSIDES are yellowed and fogged up)

e) it seems like people say the cause of the headlight problem could be a wide number of issues - and i don't have the time to try each one. i need a fairly likely cure but want to avoid creating MORE issues. you know?

oem bmw headlight xenon assemblies are uber expensive also, so does anyone have experience with an aftermarket headlight assembly replacement such as this:

https://www.protuninglab.com/hid-pro...-2d-hl-bk.html

This assembly seems to come with replacement ballasts and it's not going to break the bank.

But what if...

Is there a "what if" situation that anyone has run into with aftermarket headlight assemblies? Not just the bulbs but with replacing the ENTIRE headlight assembly?

I've been searching E46 but cannot find any definitive information.

Check the wiring inside near the bulb for damaged insulation and broken wires.

Wouldn't do it on an e46 as OE used parts are cheap enough and throw in new lenses and you have a like new OE set for under $500. Last year I bought aftermarket headlight housings for my flooded e90. I liked them as they required that I move all the hardware from the OE into the new am housings. Basically I just got new clear housings and new wiring which is exactly what I needed.

The ones you linked look like the ones I see periodically that blind folk cause they are not channeling the light properly and are never aimed right. I'd look to stay with an OE solution if possible.

Edit added pics of the e90 AM headlights.
