Headlights Bosch or TYC

Ended up finding someone on marketplace, set me up with a solid used set of Bosch headlights for a good price.

TYC or Depo are OE replacement lamps, they're good enough for insurance and/or body shops to use instead of OE. The difference is the lens material, it's a thinner, lower grade plastic.

My son bought some they looked immaculate. We compared the OEM housing to the TYC and it looked like TYC bought the molds or the engineering drawings as everything was identical, down to seam lines.

Bought some TYC replacements for my 4th gen a few years back. They’ve held up well

TYCs still rocking without any moisture two years later.

Nooo. Return them. Get the DEPO headlights. Good ZKW/Bosch sets are expensive nowadays and DEPOs are perfectly fine.

Looking some more and I ran across TYC brand and that may be what I have in my Suburban. Anyone have any experience with TYC regardless the year?

Don't get TYC. My beam pattern is poor, and I had cast metal parts inside the headlights get soft and bend from the heat.

Is the question whether the owner replaced the horrible SAE/DOT 7" sealed beam units with E-Code H4 7" from Bosch or Hella or Cibié?

TYC headlights are trash and their sealant is the main cause of letting moisture in.
