FAQs about 9003 LED Headlight Bulb

Q1: Is the 9003 bulb a high or low beam?

The 9003 is a dual-beam bulb. It comes with high beam, as well as low beam filaments. One emits a low beam, and the other provides a high beam.

Q2: Is the H4 bulbs the same as the 9003 bulbs?

In appearance, there is no difference between the H4 and the 9003. Both share the same housing, the same twin filament interior, and the same triple joint. So, of course, they are interchangeable, that is, installing 9003 bulbs in H4-equipped vehicles and vice versa.

Q3: What is the difference between a 9003 and 9005 bulb?

They are two specific types of bulbs that have different sockets/fittings. They differ in size and design. 

How to Install 9003 Headlight Bulbs?

Step 1: The headlight bulbs of your car are usually placed in the engine compartment. You can remove the headlight assembly and access them from the inside. Also, the fog light is placed right under the headlight assembly. 

The 9003 bulb compatible socket features three wires including a red wire that powers up the high beam filament. Aside from this, there's a black ground wire. Lastly, there's a yellow wire that connects to the low beam. 

Step 2: The low beam tab goes on the top of a standard socket. The left side houses the high beam tab. Similarly, the right edge accommodates the ground tap. However, sockets are likely to have different configurations.

Step 3: To identify the 9003 bulbs correctly, all you need to do is look for a double-filament. Also, the 9003 bulbs have three tabs (prongs) emerging out of a square base. Installing the 9003 headlight bulb is as simple as ABC. 

However, you must keep a few things in mind. Firstly, always use the engine compartment to access the headlight assembly. Avoid touching it with your fingers as it will damage the bulb when it heats up. Make sure you are inserting the headlight bulb correctly. Lastly, you can use an adapter if your replacement bulb isn't a perfect fit.
