If you're looking to replace your 9005 headlight bulbs, you might be wondering if you can just use H11 bulbs instead. After all, they look pretty similar and they both fit in the same sized socket. However, while H11 bulbs will physically fit into a 9005 socket, they are not functionally compatible. Here's what you need to know about using H11 bulbs in place of 9005 bulbs:
The main difference between 9005 and H11 bulbs is the wattage. A typical 9005 bulb is 60 watts, while an H11 bulb is only 55 watts. That may not seem like a big difference, but it means that H11 bulbs produce less light than their 9005 counterparts. So, if you put an H11 bulb into a headlight designed for a 9005 bulb, your headlights will likely be dimmer than before.
In addition to the different wattage, 9005 and H11 bulbs also have different shaped bases. The base of a 9005 bulb has two small pins on either side, while the base of an H11 bulb has one large pin in the middle. This means that even if you were able to somehow force an H11 bulb into a9005 socket (which we don't recommend), it wouldn't make proper electrical contact and wouldn't work correctly.
For these reasons, it's best to stick with the correct type of headlight bulb for your vehicle. If your vehicle takes9005 bulbs, make sure to use9005 bulbs - don't try to substitute withH11bulbs as this won't work well and could potentially cause damage to your car's electrical system.
