There's not.
There's not - it's fine cracking throughout the lens (crazing). I polished enough headlights as a pro to know that it's useless, and only wastes time, money, effort, pollution... So I don't think I "have" to polish just because I see others suggesting it.

The least burden would be to buy new when I speculate that the price is at a low point so I have them when these DO start leaking or get so crazed that they're not aimable/focused. And I'm not afraid to snatch the bumper skin off - I've wanted to add fog/cornering lights since I got it. The issue of new Ford headlights is also moot - a new pair would cost more than half what I paid for the whole vehicle, including auction fee, tax, registration...
But back on-topic...
Do you have any input about why Ford put a connector on them with so many extra terminals, and only uses this group or that group? Or why the PIU uses the park filament of the turn bulb, and the Explorer doesn't? Or what happens if a civvy headlamp is plugged up to a PIU connector, or vice versa? What would a PIU headlight do if power & return were applied to its Explorer terminals?
