At work i see another AE112 with the round headlights. But i see it has foglights and it looks so much nicer to me. Is it a situation of just getting lights and fitting them in. Or is there going to be issues along the way? 

 

Should be dead easy, all the parts are common Toyota bits aren't they. If you're really lucky the wiring is all in place, you might just have to buy a relay.  Hunt the wreckers and see if they have one in the yard.
