The front turn signals use a 3157A amber dual-filament bulb, while the rear turn signals use a 3157 amber bulb.
In practice, these two signals on most 2013 Avengers rely on the 3157 family, with amber coloring to match factory indicators. However, variations by trim level or market can occur, so it’s wise to verify the exact bulb by inspecting the current bulb or consulting the owner’s manual or a parts diagram for your VIN.
Turn signal bulb types for the 2013 Avenger
Front turn signals
Typically 3157A amber dual-filament bulbs are used for the front indicators, providing the amber flash required by most U.S. spec models.
Rear turn signals
Typically 3157 amber dual-filament bulbs are used for the rear indicators, aligning with the color and brightness of the front signals.
Common variants you may encounter when shopping for replacements include these two entries:
- 3157A amber dual-filament (front turn signals)
- 3157 amber dual-filament (rear turn signals)
Note that both are part of the 3157 family, with amber coloration used to match factory indicators. Always confirm by checking the bulb itself or the vehicle’s documentation if in doubt.
How to verify and replace the bulb
Use these steps to confirm the exact bulb type and perform the replacement safely.
- Park the car and release the turn signal to ensure the bulbs are cool before handling.
- Access the bulb by removing the lens or underside cover of the turn-signal housing (carefully undo any screws or clips).
- Remove the bulb socket and pull out the bulb; note the base and any markings (look for 3157, 3157A, or similar on the bulb or packaging).
- Compare the bulb to the 3157/3157A options and install the matching amber 3157 family bulb for front and rear as needed.
If you’re upgrading to LED replacements, plan for potential CAN-bus/flash-rate issues and consider resistors or a proper LED-compatible signaling setup to avoid hyper-flash or warning messages.
Summary
For a 2013 Dodge Avenger, the standard setup uses a 3157A amber dual-filament bulb for the front blinkers and a 3157 amber bulb for the rear blinkers. Always verify by inspecting the existing bulb or consulting the owner’s manual, as regional or trim variations can occur. Replacements are straightforward, and LED upgrades may require additional components to work correctly.
