Do these bolt straight to my RSX without modification?

Yes. These use the factory mounting points — no drilling, cutting, or adapter brackets needed. They drop into the stock headlight buckets the same way OEM units do.

Are the bulbs included with these headlights?

Bulbs are not included. You'll need to transfer your existing bulb sockets and bulbs from your stock headlights into these housings, or source replacement bulbs separately for both low and high beam.

What's the difference between the chrome housing and amber corners?

The chrome reflector inside the housing bounces and focuses light for better beam pattern and visibility. The amber lens on the corner is a separate turn signal indicator — it's amber to distinguish it from the white headlight beam and meets traffic laws for corner markers.
