Forenner Upgraded H4/9003 LED Bulbs, 2-Pack

Fahren Forenner's journey began over 2 decades ago with a simple yet profound vision: to revolutionize automotive lighting with innovative, high-performance solutions. Committed to sustainability and excellence, the company continues to innovate, making every journey brighter and safer for drivers worldwide.

Forenner prioritizes quality, using cutting-edge technology and premium materials to ensure safety and style. The brand's product lineup includes the Fahren Forenner H7 Bulb, the newest H11/H8/H16 Fog Lights, the newest H10/9145/9140 Lights, the Fahren Forenner Q26 Series, the Fahren Forenner Q36 Series, and other series.

The Fahren Forenner Q26 H4/9003/HB2 Fog Light represents a breakthrough in light technology, allowing drivers to bid farewell to dim stock halogens. This product offers a crisp cut-off line, strong penetration, further lighting distance, and superb brightness, all in a compact 1:1 design for easy installation.

When selecting the suitable bulb size for your vehicle, you can check the Amazon filter system, refer to the owner's manual or stock bulbs, or search for an "Automotive Bulb Guide" online. Please note that the filter system may not be 100% accurate or up to date.

One set of Forenner H4/9003/HB2 bulbs contains 2 bulbs, allowing you to purchase as needed. Some sensitive vehicle models may experience dashboard errors or flickering, which can be addressed by contacting Forenner to obtain a suitable decoder.

The decoding problem can include situations such as DRL/Bulb flickering or not working, dashboard errors (where the high/low bulb will work well), or one-side bulb not working or being dim. Forenner stands behind its products and will provide a replacement for any defective bulbs after confirmation.

The Forenner H4 9003 fog light bulbs are equipped with 2024 Latest CSP chips, providing up to 800% brighter illumination than halogen bulbs and offering superb side and peripheral visibility. The installation is quick and easy, with a 1:1 size that fits smoothly into the vehicle's housing and factory sockets, even in limited space.

The H4 HB2 bulb precisely mimics the position of the original halogen filament, with an ultra-thin 0.039-inch chip spacing, to focus the light down the road without any dark spots or scattered light, ensuring no dazzling effect for oncoming drivers.

With top-grade aviation aluminum material, dual copper substrates, and an 18,000RPM silent turbofan, the Forenner bulbs have a lifespan of 60,000+ hours, eliminating the need for frequent replacements.

The built-in intelligent IC driver makes the H4 9003 HB2 bulb compatible with 99% of vehicle systems without error. However, some sensitive models may require an additional decoder, which Forenner can provide upon request.
