Fitment notes

For the 2020 Jeep Wrangler, the low-beam and high-beam headlights both use an H13 bulb. This shared bulb fitment covers the main headlight functions, but always compare the replacement with the original connector and housing before ordering.

  • Fog lights use a 2504 LED bulb.
  • Front turn signal fitment varies: compare the original bulb to determine whether the vehicle uses 7440A or 7442NA.
  • Parking lights depend on the headlight configuration: use 7442NA with halogen headlights or 7443 with LED headlights.
  • Brake and tail lights use 3157R, while rear turn signals use 3157.
  • Daytime running lights use 7443.
  • Interior and accessory applications include 912 for the dome light, 194 for the ash tray light, and 658 for the listed automatic application.
