Compact H4 LED Bulb, 9003 HB2 H4 Fog Light Bulb Pack

Lights are the eyes of a car! Through meticulous R&D, design, production, and marketing, we have built the TECHMAX brand. From lamp bead selection and material inspection to appearance design, TECHMAX offers a wide variety of products for you to choose from. We actively respond to customer needs and promptly solve pre- and post-sales problems, providing customers with better quality and longer-lasting bulbs.

To confirm the right bulb size for your vehicle, refer to your original user manual or check the back of the original bulb. You can also search for "automotive bulb look-up" on Google to find the correct bulb size. Alternatively, you can select your vehicle model in the filter system on our product detail page.

If you experience flickering, error messages, or radio interference after installing the bulb, it may be due to the vehicle's sensitivity. We can send you decoders or resistors to fix the issue.
