Planning to replace both OE headlight assemblies that are functional but look 100 years old (already did the lens buff out treatment). RockAuto has several "Various Mfg brands" and TYC as replacements. Units all look the same and priced equally. Then there are TYC CAPA certified headlights that cost 2.3X the regular TYC's. RockAuto phone rep not much help other than saying there may be higher quality components and a guaranteed OE fit. HUGE price difference. Can anyone shed any "light" on this. Thanks.
