With a compact 1:1 design, this bulb is easy to install.

When selecting the suitable bulb size for your vehicle, we recommend checking the Amazon filter system, your owner's manual, or searching 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, and you can purchase as needed. However, some sensitive vehicle models may experience dashboard errors or flickering. In such cases, please contact us to obtain a suitable decoder to address the issue.

The decoding problem can occur in various situations, including DRL/Bulb flickering or not working, dashboard errors (where the high/low beam bulb will work well), or one-side bulb not working or being dim. We stand behind our products, and if you encounter any issues, please message us, and we will help you solve them, providing a replacement for any defective bulbs.

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 3-minute installation is straightforward, with a real 1:1 size that fits seamlessly into the vehicle's housing and factory sockets, even in limited space. The perfect beam pattern precisely mimics the original halogen filament, focusing the light down the road without dazzling oncoming drivers.

With a lifespan of 60,000+ hours, these bulbs feature top-grade aviation aluminum material, dual copper substrates, and an 18,000RPM silent turbofan to rapidly and effectively dissipate heat, 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 can be obtained by contacting Forenner.
