White is the daily. This kit lets you run both — and switch between them without pulling a panel, opening an app, or touching a wire. Three flashes of the high beam stalk is all it takes. The module saves your last selection to memory, so the car wakes up exactly how you left it.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eUnder the hood it's a complete LED board swap for both housings — not a film, not a tint, not a wrap. Real CSL yellow output on dedicated boards, with OEM switchback turn signal behavior completely intact.
