Headlamp condensation problems

[boilermender]

The previous owner fitted after market zenon's to the zed 4, e85, I replaced them back to halogens's not wanting after market gear on the car, and for what they cost, but since then I have condensation in the drivers side lense which is sending me nuts, Had a brief look and noticed holes have been gouged out and not drilled to take the zenons and poorly repaired, tried all kinds of methods but still no good, at the stage of looking to fit complete new lenses. are the ones on ebay you see for 300 ish any good, thoughts on the whole issue plz

condensation will be due to some sort of leak /non sealed unit.

it might be worth buying a new one or trying to seal up any non oem holes
