Will these mount directly where my stock headlights are?

Yes. These use factory mounting points, so they bolt into your existing locations without modification. No drilling or adapter brackets required.

Do the amber corners work as side markers?

The amber corner sections are integrated into the housing. Functionality depends on whether your wiring harness supports side-marker output — check your vehicle's electrical setup before installation.

What prep work do I need to do before installing these?

Remove your factory headlights and test-fit these assemblies first. Inspect the mounting points on both the headlights and vehicle for any debris or damage. Once you confirm fit, mount them and reconnect the wiring harness.
