DOT / SAE-SPEC: Both the DRL and Sequential Models are fully DOT/SAE spec for illumination, signaling, and Daytime Running Light functions. Illegal? Not so much.
ASSEMBLY: These are made utilizing OEM-spec materials such as a UV-coated Polycarb lens, powerful Bi-LED projector, and molded ABS plastic rear housing. The wiring is all OEM grade and allows for easy plug-in to the stock wiring without modification (verify your car uses 12-pin headlight connectors!).
