does anybody know how hard it would be or what mods would need to be done to install jdm one-piece headlights into my usdm 91 civic hatch? i heard it was just little modification.

 

from what i understand [little]
they are not street legal due to the right hand drive setup
they point in the wrong direction [to the leftish]

but i have been wrong and do plan on being wrong again [sometime!]

 

since the headlights are longer, have different angles and different corner shapes, there is few mods:

hood, fendes, some upper filler piece

 

If you just want the lights you might as well get the whole front end, since you will need most of the pieces to get hte lights to fit.

 

i agree with that.

you will need

hood,
fenders (optional),
filler piece,
front bumper,
and radiator support

fender have JDM side markers....niiice touch

 

arent the usedm headlights better?
us are glass jdm are plastic and have weaker light patern.

 

yep my JDM healights are plastic BUT they are very durable...the USDM glass headlights weigh a ton....the JDM EFs are lighter than the USDMs because the bumpers don't come with reinforcements...giving you about 30lbs of the front end, 30 lbs of the back

 

1 Piecers only came on Civic four doors....so you would have to convert to the 4 door front end which looks the same way as a US 4 door front end with the addition of 1 piece headlights and sidemarkers......
