The front turn signals on a 2013 Toyota Tacoma typically use a 7440-type bulb, while the rear turn signals use a 3157-type bulb. Some markets or trims may differ, so verify by inspecting the bulb or checking the owner's manual.
This article provides a practical overview of which bulbs are used where, how to identify the correct size, and where to buy suitable replacements for a 2013 Tacoma.
Bulb sizes by location
To help you replace a dead blinker quickly, here are the common bulb sizes for the 2013 Tacoma's turn signals. Remember that there can be variations by trim or region.
- Front turn signal bulb: 7440 (amber). Some cars may list 7440A or 7440NA variants; confirm the exact bulb by removing the current bulb or checking the lens markings.
- Rear turn signal bulb: 3157 (amber). Some models use 3157A; verify the exact variant on your vehicle.
When replacing, use the correct color amber bulbs to maintain visibility and comply with regulations. If you're upgrading to LEDs or higher brightness bulbs, ensure the vehicle's CAN bus system accepts them or install load resistors as needed.
Replacement options
Below are common, widely available replacement options you can consider. The list covers standard incandescent bulbs and some LED equivalents that fit the same bulb bases.
- Front turn signal: 7440NA, 7440, or 7440A amber bulbs (check compatibility with your 2013 Tacoma's front socket).
- Rear turn signal: 3157NA, 3157 amber bulbs (or 3157A if specified for your vehicle).
Choose reputable brands such as Sylvania, Osram, or Philips, and carry spares for roadside maintenance. LED options may require load resistors to prevent hyper-flashing or error codes on some trucks.
How to verify the correct bulb in your truck
If you're not sure which bulb your truck uses, you can verify it with a few quick checks. Turn off the lights, remove the lens or access cover, and compare the bulb base to the numbers stamped on the bulb or socket. You can also consult the owner's manual or a service bulletin for the exact part numbers by VIN/trim.
Step-by-step quick check
Steps to confirm the bulb size:
- Identify whether you are replacing the front or rear signal bulb.
- Carefully remove the bulb and note the base type and stamped numbers (e.g., 7440 or 3157).
- Match the base and filament count to standard bulb sizes listed above, and purchase accordingly.
If you prefer professional help, a Toyota dealer or a qualified automotive technician can confirm the correct bulbs for your specific Tacoma model and trim.

For a 2013 Toyota Tacoma, the typical turn signal bulbs are 7440 for the front and 3157 for the rear, with some variations by market or trim (such as 7440A/7440NA or 3157A).
