Good move :-) I can't quite remember where I got my lights/lenses from, possibly from a later-model Lancer, but I would imagine it should be easy to find a round driving light casing that would fit as a replacement. But definitely do it... much better than the old-school sealed beams!
Yer ive only kept them so long cause bush bashing having sealed lights stopped the water but now that ive gunna respray and things thats not gunna happen anymore
I remember ages ago the guy at autobarn said he could get me something to do it but i was more wanting to find something on evilbay or something that might be cheaper hahah but if all fails i can go back to him
Autopals are a good quality brand too, fairly cheap on ebay and are the H4 conversion lights. Come in both 5.75" and 7" lights, bought a set for my wagon last year.
