2004 Toyota Tacoma headlight bulb size

The 2004 Toyota Tacoma uses different headlight bulb sizes depending on the specific trim level and headlight configuration. Generally, two main types of headlight bulbs are used in the 2004 Tacoma: halogen bulbs and high-intensity discharge (HID) bulbs.

The most common size used in the 2004 Tacoma is H4/9003 for the halogen headlight bulbs. This size designation refers to a dual-beam bulb, which means it functions as both a high and low beam. The H4/9003 bulb has a single base with three connection pins.

The bulb size would be different if your 2004 Tacoma is equipped with HID headlights. HID bulbs come in different sizes based on their type, such as D2S, D2R, or D4S. However, it’s worth noting that HID bulbs are not as common in the 2004 Tacoma models and are typically found in higher trim levels or aftermarket installations.

To determine the exact bulb size for your specific 2004 Toyota Tacoma, it’s recommended to consult the owner’s manual of your vehicle. The owner’s manual should provide detailed information on the correct bulb sizes and types for high and low-beam headlights.

If you don’t have access to the owner’s manual, another option is to inspect the existing bulbs in your Tacoma’s headlights physically. Remove the headlight assembly or access the back of the headlight housing to locate the bulb. The bulb should have a marking or label indicating its size and type.

Additionally, you can contact a Toyota dealership or a certified automotive parts store for accurate information about the specific bulb size required for your 2004 Tacoma. They can provide the correct bulb size based on your vehicle’s trim level and headlight configuration.

It’s important to use the correct bulb size when replacing headlights in your 2004 Toyota Tacoma to ensure proper fitment, functionality, and road safety.
