Anyone know? Picked up and ef si and these came with it. No use for them

 

The lights on the left are JDM EF8/EF9 headlights (also found on 90/91 EF6 and EF7). They will not fit a USDM front end, only a JDM or Euro VT front end because of the shape. The angle of the beam will shine into oncoming traffic if driven on a car in right-hand traffic (ie: North America) and they cannot be adjusted to compensate fully for this since the beam direction is dictated mostly by the rectangles embedded in the plastic.

The ones the right look like 88-91 Civic/CRX glass 2-bulb headlights from North America.
