Help: Rescue a Fading Foglamp Lens

[20vanda01]

'Yon pong fog lamp (lens-pinaka salamin) ng XUVi sa left side ay nagiging yellowish na, unlike 'yong nasa ride side na clear pa talaga. I remember last time, pinapalitan ko ito sa Isuzu nung under warranty pa dahil nagmomoist sa loob nung fog lamp. Clear at bago naman ang ipinalit pero 2+ years after nagiging yellowish na, very light pa naman kaso in the long run tingin ko papangit na 'yon at magiging talagang obvious na.

How can I rescue this?

is the foglamp they replaced 2 years ago eh, orig isuzu? my experiece kasi from a taiwan made foglamp is that pinapasukan ng tubig then natatanggal yung chrome part nung foglamp, sa ilalim ng chrome may parang yellowish material..so nagiging kulay dilaw tingnan. happened to me before.

Ikinumpara ko 'yong left and right fog lamps pero alang markings to differentiate if the replaced left fog lamp is orig Isuzu or Taiwan made. Siguro nga Taiwan made kasi nagdegrade na 'yong quality.
Inisip ko gawin kung yellow na lang pareho, by applying paint outside the lens, pede ba 'yon?

Decided to buy a foglamp for the Crosswind na lang, naiirita ako pag nakikita ko na di pantay ang kulay ng lens... any suggested place/shop to buy?
