I bought least expensive on-line six months ago. $100/pair at RockAuto, roughly. Replacing TYC seen from circa 2012. Last buffed out about a year prior. New pair seem fine.

I’ve used products which claim to preserve such, but Texas heat & sun deny those claims.
It has always angered me that these
plastico headlamp assemblies are expensive when OEM and not warrantable as it’s a safety issue. In combination with what everyone knows is a poor amount of light projected . . . I can run properly adjusted High Beam and not get flashed (a function of who’s on our roads these days ignoring flashes by others who have given up as, partly, that the dark-eyed can’t see as well at night as those with lighter-hued eyes and who just don’t give a D about others, besides).
When in 2012 I bought the first set the OEM were nine years old. Somewhat worse than what’s seen above. Dealer replacements were $339/ea at that time.
Investigated trying a relay-drive harness with upsized wiring , but it wasn’t possible without modification plus that output voltage was still about right (OEM wiring okay).
“New” (when I see other vehicles of any type) say to me the owner is being conscientious, and also that the vehicle looks distinctly better in every regard.
Adding supplemental been on a list a long while. Metro areas have enough street lighting I haven’t yet made it a priority, and that annual miles are extra-low. So, sorta glad I’ve held off as LED has come along to hopefully help remedy that in the future.
Since 2012 I’ve used Phillips tri-color. Still a few sets around. .”
NightGuide headlamp bulbs feature special technology that projects specific colors of light into three distinct visual zones.” This bit of contrast works.
Thus:
Cheap assemblies improves what’s needed as to appearance and OEM-level performance as even Factory isn’t much good. $100 every so often, then, plus new lamps (dim as they age).
