The Mercedes-Benz W124 is a benchmark sedan produced from 1984 to 1993, available with several engine options, including the 200, 230, 260 and 300. Recognized for its legendary reliability and build quality, the W124 is today a classic highly appreciated by Mercedes enthusiasts.
For the dipped beam and the high beam, the W124 uses a dual-filament bulb with a H4 base, which provides both functions in a single headlamp unit. Replacing it with H4 LED bulbs offers a significant improvement in brightness, an important advantage for this period vehicle, whose original optics produce limited lighting.
The front and rear turn signals use bulbs with a PY21W base (with a white turn signal lens) or P21W (with a yellow lens), depending on the version. The license plate light uses C5W festoon bulbs.
The Mercedes W124 has a classic electrical system, without CANbus multiplexing. Installing LED bulbs is therefore generally simple and straightforward, without the need for additional anti-error modules.
