For the 2020 Dodge Challenger, the low-beam and high-beam bulb fitment depends on the headlight type. Models with halogen headlights use a 9012 bulb for both low and high beam. Models equipped with HID headlights use a D3S bulb for both functions.
The fog light uses an H11 LED bulb. Front turn signals, rear turn signals, brake lights, reverse lights, tail lights, parking lights, side markers, the center stop light, and license plate lighting are listed as LED applications.
Interior fitment includes a 578 dome light and 578 map light. The glove box may use either a 194 or 7441 bulb, while reading lights may use either 2825 or 98. The interior and trunk light applications use a 567 bulb. Confirm whether the Challenger has halogen or HID headlights before ordering the low- or high-beam replacement.
