Does the Emgrand require a decoder when retrofitting xenon lights?

[Marley]

The Emgrand does not require a decoder when retrofitting xenon lights; only an HID ballast needs to be added. Xenon Light Decoder: A decoder is essentially a resistor or capacitor component on the power supply side. It is connected in series in the 12V circuit of the ballast to prevent the vehicle's computer from triggering an alarm. Different vehicles require different decoders, mainly to address issues like insufficient xenon light power or interference with the vehicle's computer. The decoder is typically a small plastic box. Components of Xenon Lights: HID xenon lights generally consist of a bulb (xenon lamp), an electronic ballast (also known as a stabilizer, voltage regulator, or transformer), and a wiring control box.
