Will these bolt straight to my factory mounting points?

Yes, these are designed as direct replacements to OEM side markers. Mounting method aligns with factory rocker and bumper attachment points — no drilling or custom brackets needed.

Do these LEDs need a separate harness or resistor?

Installation harness and resistor specifics depend on your vehicle's wiring. Test-fit before committing to any permanent splicing, and reference your service manual for bulb load compatibility if you're concerned about warning light behavior.

Can I repaint or modify the crystal smoke finish?

The crystal smoke is a tinted lens finish. If you want a different look, sanding and repainting is possible — just test on a small area first to confirm adhesion. Avoid aggressive solvents that may damage the LED housing seal.
