This application discloses a multi-color decorative light control device and a vehicle. The multi-color decorative light control device includes an input filter circuit, an input protection circuit, a first colored light, a second colored light, and a third colored light. The input filter circuit is electrically connected to the power supply terminal of the vehicle control module, and the input protection circuit is electrically connected to the input filter circuit. The positive terminals of the first, second, and third colored lights are respectively electrically connected to the input protection circuit. The negative terminal of the first colored light is electrically connected to the first control terminal of the vehicle control module, the negative terminal of the second colored light is electrically connected to the second control terminal of the vehicle control module, and the negative terminal of the third colored light is electrically connected to the third control terminal of the vehicle control module. The applied multi-color decorative light control device has a simple and reliable circuit and can use higher power LEDs to improve brightness, thus enabling easy identification even in daytime environments.

A patient monitoring sensor having a communication interface, through which the patient monitoring sensor can communicate with a monitor is provided. The patient monitoring sensor includes a light-emitting diode (LED) communicatively coupled to the communication interface and a detector, communicatively coupled to the communication interface, capable of detecting light. The patient monitoring sensor includes a layer of material is provided over the LED on the patient-side of the sensor to reduce transmission of heat therefrom to the skin of the patient.
