switching halogen to led

Hi, my name is Devin. I'm an auto repair expert with the Car Genius team at RepairPal. I'm so sorry to hear you’re having trouble with your vehicle. Switching from halogen to LED can be tricky, especially with a vehicle like the C300, which is sensitive to changes in electrical components. Flickering usually happens because of the difference in resistance between the original halogen bulbs and the new LEDs. Installing load resistors may help prevent flickering by mimicking the resistance of halogen bulbs. However, the best bet is to use the manufacturer's recommended bulbs in your side marker lamps and eyebrow lights. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered.
