Does the new generation Focus require a decoder for installing LED lens headlights?

The new generation Focus does not require a decoder for installing LED lens headlights. The lens only serves to focus the light, while xenon lamps require a decoder. LED lenses are closely integrated with LEDs to enhance light utilization and luminous efficiency, and can be used for different effects. Composition of car headlights: Headlights consist of a lamp cover, bulb, lamp holder, reflector, lens, and light adjustment device. Working principle of car headlights: The working principle of car headlights is that the central intelligent control chip determines the brightness changes of the external environment based on the light sensor to complete the operation of turning the lights on and off.
I upgraded my new Focus with LED projector lights, and from experience, this car requires a decoder. The new car's electronic system is smart and monitors circuit resistance. The original halogen bulbs have high resistance, while the low resistance of LEDs can cause the computer to misjudge a bulb failure, resulting in constant dashboard warning lights. When installing the lights, I forgot to add the decoder, and as soon as I drove out, the lights started flickering, scaring me into rushing back to the shop. The decoder is a small accessory that simulates the correct signal to avoid these issues. After the upgrade, the light beam is more focused, making night driving much clearer, but it's still important to adjust the lights properly to avoid dazzling others. Don't skimp on this step to save money—safe driving is crucial. I recommend finding a professional modification shop for a one-stop solution, saving time and hassle.
