So there was a jdm ef sedan that came with the 1pc headlamps and corner lamps in one solid integrated unit.

I've always thought it would look awesome on an ef hatch.

Has anyone seen this conversion done before?

What is needed to convert?

 

You can make them fit just like you can make any headlight fit.
It's a hack job.

Doing the conversion on a SEDAN requires the entire radiator support to be replaced - this requires a lot of spot welds to be drilled out to get the original one off and then the JDM one gets welded in place.
Then the hood, fenders, bumper, ... basically the entire front end, gets replaced with the JDM parts.

To fit them to the hatch, you cut everything that interferes with the headlights and then get very creative to develop a way to mount them.
