For the 2013 Dodge Dart, headlight bulb fitment depends on the headlight type. Models with halogen headlights use a 9012 bulb for both the low-beam and high-beam functions. Models equipped with HID headlights use a D3S bulb for both low and high beam, so confirm the installed headlight system before ordering.
The fog light fitment is listed as H11 LED, H16 LED, or H8 LED. Front turn signals and parking lights use 7442NA bulbs, while the front side marker uses 194NA. The reverse light uses a 7440 bulb.
Several rear lighting functions are listed as LED, including the brake lights, center stop light, tail lights, rear turn signals, and rear side markers. License plate lighting may use either a 168 or 917 bulb. Interior fitment includes 2825 or 98 bulbs for the dome and map lights, with a 567 bulb listed for the trunk light.
