I have a reserve with xenon lights, does anyone know if I change them out for aftermarket led bulbs will it throw an error code on the dash?
You would have to check the power consumption of the LEDs to see if similar to the 35w ballast draw on HIDs that came with your car. If they are much lower than 10-20% you may get codes/hyperflash. Keep in mind most LED headlight bulbs are made for reflector lenses as the light emits from two sides of the bulb. You will get a vertical area of poor light in a projector housing like the MKC uses. The HID D3S is 360 degree light.I have a reserve with xenon lights, does anyone know if I change them out for aftermarket led bulbs will it throw an error code on the dash?
Glad I was not alone. I was very disappointed with the output with a modified system (a motorcycle). I did replace my (murano) halogen headlight assembly with led assemblies factory made for led and it was very nice upgrade. I heard reflectors are built for bulb type and this was the reason I assumed I was satisfied with one modification and not the otherWhy would you want to replace them with LED? HID will be the brightest of all bulb types in headlights. The MKC has the brightest lights I've ever seen on a car, even brighter and better light output than other models from other automakers such as BMW and Mercedes from personal experience. In the dark they're as bright as the sun and I have zero issues seeing the road at night. In fact, I don't even need my glasses. My old car had halogen bulbs and I put in LED bulbs from OPT7 and I wasn't satisfied. The light output wasn't even and too much of it pointed to the ground. The headlight design was a projector beam. It's designed to accommodate what the automaker originally intended for people to use so using different bulb types may have bad light output. I didn't adjust the aim at all. Since then I vowed to never mess with headlights again and just leave it the way it came from the factory. It's not worth the time and energy. If bulb replacement is needed I'll only use what it originally had and what it's designed for. I don't think it's worth messing with.
