H11 Headlight Bulb

What Are H11 Bulbs? – Just like all other filament bulb types, the H11 is a form of incandescent lighting where electrical current flows through a thin metal filament causing it to heat up and produce light. The H11 emits a very bright and crisp white light, which is why it’s popular for use in automotive lighting.

H11 bulbs are also known as HB3s or 9004s , depending on their base type (size). H11 bulbs can vary in wattage, but most will produce 55 watts at 12 volts. They have an extremely long lifespan , lasting many hundreds of hours. They are also very energy efficient, meaning they produce little heat emission and can be used in locations where heat would damage other bulbs.

H11 Bulbs Replacement Guide

These instructions are for replacing an H11 or HB3 bulb with a new H11/HB3 bulb. The steps to replace an HID conversion kit are similar but require different tools. For more information on how to install these kits, check out the video below:

Tools Needed: 1/4 inch ratchet & 10mm socket 3/8 inch ratchet & 8mm socket 3/8 inch drive extension (optional) Pliers.

Replacement Step #1 – Open Hood First, open the hood of your car by pulling up on the hood release lever that is located near your steering wheel.

Replacement Step #2 – Prepare Bulbs Before handling any bulbs, be sure to disconnect both battery terminals by loosening their bolts with a 1/4-inch ratchet and socket. Then, use pliers to carefully loosen up each metal clamp holding the old bulb in place.

Replacement Step #3 – Remove Old Bulbs Once the old one has been removed, install the new H11 or HB3 bulb by inserting it into the socket until you feel resistance. Carefully tighten down the retaining rings on either side of the base until they are snug against each other (if equipped). Your new light should now be secure and ready for operation.

Replace #4 – Reconnect Batteries.

Replace #5 – Test New Bulbs Finally, reconnect the negative battery terminal first and then the positive. Be sure to only use a 10mm socket for this process. Once both terminals are secure, test your new light by turning your headlights on using your car’s headlight switch . If everything is working properly, you should see a bright white light emanating from each bulb.

If they do not work, check to see if they are firmly seated by rotating them slightly with your hand. Also inspect the electrical connectors at the back of both headlights for any corrosion or damage that may be impeding proper contact between the circuit and bulbs.

H11 Bulb Dimensions

H11, as the name suggests, belongs to Group 1, which shows that you can use them as your headlight bulb fittings. What’s more, you can use the H11 lamps to solve any of your other lighting needs. Today, they are a common replacement part.

If any of your fog light or parking light need a replacement and you have the H11, do not look any further. Use it and no law enforcement officer will question you.

H11 lamps are dual beam bulbs. They have only one filament. And you can use them either as a projector or reflector headlights. But most savvy drivers think that they are best used as reflectors. By using them properly, you increase the chances of increasing the lifespan to two years. Most halogen lamps have a relatively short service duration, and the H11 is not exempted.

These bulbs use PGJ19-2 base and have a nominal power of 55 watts at 12 volts and 70 watts at 24 volts. Evidently, they have the ability to meet most of your automotive lighting needs. But if you are like most experts, you know that halogen technology has a few defects. In particular, H11 bulbs have short lifespans and they sometimes produce inadequate light. The good news is that you can upgrade your H11 bulbs to LED and HID light at any time to get a better service.

Tips

• Installation is easy in most models; however, you may need professional assistance.
• LED bulbs can get hot at the bottom and require cooling systems such as fans or heatsinks to prevent them from melting.
• When aligning your LED headlights, make sure they point slightly downwards and away from oncoming traffic so they don’t blind other drivers.

FAQs

Q: Are LED H11 headlights legal?
A: Every state has its own laws about LED headlights, but they are usually legal if they project a light beam that illuminates the road ahead between 50 and 100 meters.

Q: Can I replace H11 bulb with LED?

Yes you can. There are many people out there who try to find the most energy efficient light bulbs for their car. The HID conversion kit with LED bulbs is one of the best options in this case because it provides bright white light which is similar to daylight. These kinds of lights can be installed in both headlights and fog lamps.

You can also replace your current halogen or HID headlight bulbs with LED ones but you need to know that they won’t fit without some modifications. If you don’t want to change your existing housing then you’ll have to connect LED bulb directly instead of using an HID wiring harness adapter. Of course, it will require some extra effort since LED doesn’t emit much heat so it needs constant cooling while operating.

Q: What’s the difference between H11 LED headlights and H11 HID headlights?
A: Both types are superior to halogen lights. HID lights tend to be brighter, but they can reflect light back at you in foggy conditions and blind other drivers. In addition, HID lights experience a delay before they turn on.

Q: How much power do H11 LED headlights consume?
A: LED lights are relatively new technology, and they are incredibly energy efficient. Most models use between 30 and 60 watts.

Q: Do LED lenses turn yellow over time?
A: No. Most high-quality LED lenses are designed with a polycarbonate material that features an ultraviolet additive, which is not affected by sunlight.

Q: H11 LED headlights are ideal for what types of driving conditions?
A: Compared to halogen bulbs, LED headlights are better-equipped to handle extreme weather conditions, i.e., very hot or very cold temperatures.
