LED CANbus Some car models present particular challenges for LED-based retrofit lamps. When upgrading your car with LED bulbs, a few challenges may occur such as an error message on the dashboard, flickering, or dimming effect. These error messages don’t mean the LED bulb itself is faulty. Therefore, we have developed smart solutions to overcome those challenges. Philips’ unique CANbus adapters* ensure the vehicle’s lighting systems function smoothly, for reliable electrical performance over time. *Philips Light Repair CANbus functionality is directly integrated into our new-generation bulbs to prevent flickering. Generally, no need for additional accessories. In some rare cases, depending on your car model and other parameters related to your car computer, an additional CANbus might be required to further reduce the flickering effect. Please note a separate Adaptor CANbus may still required. It is your own responsibility to ensure that the use of the LED retrofit lights complies with applicable local legal requirements. ## Features - Up to 350% brighter light* - 5.800 Kelvin colour temperature for cool white light - Enhanced lifetime of up to 5.000 hours - Compact all-in-one design for plug-and-play use - It is your own responsibility to ensure that the use of the LED retrofit lights complies with applicable local legal requirements - Find out if you need additional adapter rings to upgrade to LED, check Philips LED compatibility list at Philips.com/LEDcompatibility-check - Packaging may vary ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BKSTZMC5 | | Auto Part Position | Front | | Best Sellers Rank | 242,920 in Automotive ( See Top 100 in Automotive ) 659 in Special Car Bulbs | | Brand Name | PHILIPS | | Brightness | 350.0 lumen | | Color Temperature | 5800 Kelvin | | Colour | 5.800K | | Customer Reviews | 4.3 4.3 out of 5 stars (73) | | Included Components | Set of 2 LED car bulbs H4 | | Item Type Name | Ultinon Pro9100 LED car headlight bulb (H4), +350%, 5.800K, set of 2 | | Light Output Maximum | 350 Lumens | | Light Source Type | LED | | Manufacturer | Lumileds | | Manufacturer Part Number | 11342U91X2 | | Manufacturer Warranty Description | 5 years | | Model Number | 1866394 | | Number of Items | 2 | | Operating Life | 5000 Hours | | Package Quantity | 1 | | Specific Uses For Product | Head light | | Unit Count | 2.0 count | | Voltage | 12 Volts | | Wattage | 18 watts | ## Product Details - **Brand:** PHILIPS - **Brightness:** 350.0 lumen - **Colour temperature:** 5800 Kelvin - **Light source type:** LED - **Specific uses for product:** Head light ## Images ![Philips Ultinon Pro9100 LED car headlight bulb (H4), +350%, 5.800K, set of 2 - Image 1](https://m.media-amazon.com/images/I/81+OTtLEqYL.jpg) ## Questions & Answers **Q: Can anyone confirm if they pass MOT?** A: No guarantee they will on your car but mine did on a '54 X-Trail.
