When it comes to vehicle lighting, the choice of bulb can significantly impact visibility, safety, and aesthetics. Today we will focus on the H11 | 711 bulb and the various options available, This guide delves into everything you need to know about H11 bulbs, from Halogen to LED and Xenon HID variants. 

Understanding H11 Bulbs

H11 Halogen bulbs are widely used in vehicles for headlights and fog lights due to their powerful illumination and durability. H11 Halogen bulbs can produce up to 1000 lumens and are often upgraded to either Xenon HID or LED to increase light output.

Benefits of Upgrading to a H11 Xenon HID Conversion Kit

H11 Xenon HID Conversion Kits provide several advantages over traditional halogen bulbs. They produce a brighter light up to 3500 lumens, a choice of colours (5000k, 6000k 8000k) when combined can improve visibility in night driving and adverse weather conditions. 

Benefits of Upgrading to H11 LED Bulbs

H11 LED Bulbs are all of the above but better! Producing up to 12,000 Lumens which is a staggering 1100% increase over the standard Halogen Bulbs. LED Bulbs don't come with the option of choosing the colour, the manufacturers often decide this and usually choose in between the range of 5500k and 6500k, This produces a crisp white light with maximum performance. 

H11 LED Bulbs are often a like for like replacement, meaning no addition Ballasts unlike the H11 Xenon HID Conversion Kit. Making them easier to install and take up less space.

How to Choose the Right H11 Bulb

Selecting the right H11 bulb involves considering factors such as:

  • Colour Temperature: Ranging from warm yellow to cool blue, the colour temperature affects visibility and driver comfort.
  • Lumens: The brightness level of the bulb. Higher lumens mean brighter light.
  • Installation: Like for like or a little more complicated.
  • Canbus: Does your car use the Canbus system to warn of any bulb faults?

Installation Guide for H11 Bulbs

Installing H11 bulbs is a straightforward process that can be done at home with basic tools. We will briefly explain the differences below..


    • H11 Halogen Bulbs: Like for like, simply take the old halogen bulb out and install the new halogen one.
    • H11 Xenon HID Conversion Kits: A little more complicated because the H11 Xenon HID Bulb requires a ballast to power it. So once you replace the  Halogen bulb with the Xenon HID Bulb you then have to connect the ballast to the bulb and then connect the ballast. It's not rocket science but its still one more step to take.
    • H11 LED Bulbs: Like for like, simply take the old halogen bulb out and install the new LED one.

    Common Issues and Troubleshooting

    Onboard car computer systems (CANBUS) are often used to monitor the car for any issues or faults, if a issue or fault is found then it can display a warning light on your dashboard to make you aware. 

    One of the systems that is often monitored is the lighting system. The onboard computer monitors the bulbs resistance, if the bulb was to fail then it detects the fault and displays a warning on the dash. (Not all cars do this)

    When choosing to either replace or upgrade your H11 Bulbs this must be taken into account, whether or not your vehicle is monitoring the lighting system. The easiest way to do this is if you already have a failed bulb and that's why you are replacing it, do you have a warning message or light on your dashboard? If you don't have a failed bulb and are just upgrading, then you can always just take one bulb out and again check to see if you have any warning messages or lights on your dashboard. 

    Our H11 Xenon HID Conversion Kits are 99.9% error free, meaning the ballasts used in our kits have the ability to cancel any errors that may arise from changing from Halogen to Xenon.

    Our H11 LED Bulbs come in both Non-Canbus and Canbus meaning you may get errors if your vehicle has such a system and you choose the wrong type, just keep this in mind when making your decision and order Canbus if needed.

    FAQs About H11 Bulbs

    Q: Can I replace H11 Halogen bulbs with LED or Xenon HID?
