Do these use plug-and-play connectors or do I need an adapter?

Mounting and connector type not specified — check your OEM connector before ordering to confirm compatibility or plan for wiring adaptation.

Will the LED brightness trigger a hyperflash or error code?

LED tail lights sometimes require a load resistor or flasher module to prevent fast blinking. Test-fit first, and add a resistor kit if needed.

Are these sealed against water and road spray?

These ship brand new, but long-term waterproofing details aren't confirmed — inspect the seal around the lens before installation and re-seal if necessary.
