i always liked how the is250 conversion looked on some cars. how hard would it be to do it on an accent? heres are pics for reference:

 

I dont know how easy the smaller ones on the trunk would be but the taillights would be easy, it just looks like a cover with a circle in the center.

 

That's the IS300.

 

The smaller lights wouldnt be too difficult. You would have to get the lights, measure the right diameter circles, and cut the holes in the trunk. Then you would have to fab up some kind of brackets to hold the lights in. You would also want to make sure you get some rubber moldings and make sure its a very tight fit, or else you would end up with water and stuff inside your trunk. The lights probably already come with rubber moldings. Not sure.

But once you cut out the holes and have the brackets fabbed up, it then just a matter of prepping and finishing the body work with filler/bondo/fiberglass, primer, and paint. Then just wire up the lights, and you're good to go. Fairly easy project, that I'm sure any body shop could easily do if you werent comfortable doing it yourself.

 

I forget who did it, but someone already did that to an LC. It looked alright, I would say more unique than actually looking good.
