For the 2012 Dodge Challenger, headlight bulb fitment depends on the factory headlight type. Models with halogen headlights use an H13 bulb for both the low beam and high beam. Models with HID headlights use a D1S bulb for both functions. Confirm the headlight configuration before ordering, since H13 and D1S bulbs are not interchangeable.
Other exterior lighting includes a 4157NA bulb for the front turn signal and parking light, 921 for the reverse light, and 3057R for the brake and tail lights. The rear turn signal uses 3057, while the front and rear side markers use 168NA. The center stop light is LED.
Interior applications include 578 for the dome and map lights, 2825 or 98 for courtesy and reading lights, 194 or 7441 for the glove box, and 567 for the interior and trunk lights. License plate lighting may use either 168 or 917.
