For the 2018 Lincoln Continental, headlight bulb fitment depends on the factory headlamp system. Models with HID headlights use a D3S bulb for both the low beam and high beam. Models with LED headlights use LED lighting for both functions. The fitment data also lists LED for the low and high beams generally, so confirm whether the vehicle has HID or LED headlamps before ordering.
Front turn signal fitment varies as well: halogen-headlamp models use a 7444NA bulb, HID-headlamp models use a 3757A bulb, and LED-headlamp models use LED lighting. The reverse, brake, center stop, daytime running, parking, front and rear side marker, tail, rear turn signal, dome, map, and trunk lights are listed as LED.
For the license plate lights, compare the original bulb before purchase. The listed options are 2825 or 98 under Option 1, while Option 2 uses LED. No fog light bulb fitment is listed.
