For the 2013 Toyota Tacoma, the low-beam and high-beam headlights both use a 9003 bulb. This shared fitment makes the 9003 the primary headlight replacement to check when servicing either beam.
Fog-light fitment is listed as either H11 LED or H16 LED, so verify the existing fog-lamp application before ordering. Other exterior lighting varies by equipment, especially on models with LED tail lights.
- Front turn signals, daytime running lights, and parking lights use 4157NA.
- Reverse lights use 921, while front side markers use 2827.
- With LED tail lights, the brake, tail, and rear side-marker lights are LED. Without LED tail lights, the brake and tail lights use 3157R, and the rear side markers use 3157A.
- The center stop light and license-plate lights may use 168 or 917.
- Interior lighting includes a 578 dome bulb; map lights may use 168 or 917.
Confirm the truck’s lighting configuration and the bulb currently installed where multiple options are listed.
