Lights getting yellowish

my front head lamps are plastic and this gets yellowish when its old.... tell me some way to make it look original again.....

is there a way to take off the laquer(corting) sort of thing in the lamps

thanks..................

are they stock?

chome polish will take it off if its not read bad, if its bad then replace them.

He needs some of the halogen bulb fluid doesnt he? LMAO. Really just go down and get some plastic or acrylic polish Our autozone and kragens have it most any parts store have it. then just polish out the out side. OR you can get some glass ones. (i thought all were glass maybe different problem)
If its glass and the inside is getting all yellow its cause it dirty. Pull out headlight spray inside were the bulb goes with simple green and swish around do it a couple times. Then wash out with water and put it in the sun let it dry completly if you dont it will dew up inside.

I thought all Civics came stock with glass?
