Main Features

Daylight-Level Visibility

Frequently Asked Questions

Are these 9004 LED headlight bulbs compatible with my vehicle's Canbus system?

Yes, the S7S series is specifically designed to be CANbus-ready. With a power output of 65W per bulb, they closely match the draw of factory halogens, preventing error codes and flickering on 99% of vehicles.

How do I know if I need a 9004 halogen bulb replacement or a 9007?

While they look similar, 9004 bulbs have a horizontal filament orientation, whereas 9007 is vertical. Always check your vehicle owner's manual or the marking on your existing bulb to ensure you select the correct 9004 bulbs.

Will these 9004 LED headlight bulbs blind other drivers?

No. The S7S series features a 1:1 beam pattern design that matches the original halogen focal point. When installed correctly, they provide a sharp cutoff line that keeps light on the road and out of the eyes of oncoming motorists.

Is the cooling fan loud on these high-power LED bulbs?

The S7S utilizes a high-speed, silent cooling fan. While it is powerful enough to keep the 9004 130W bulbs cool, it operates at a frequency that is virtually imperceptible from inside the cabin.

Can I install these myself or do I need a mechanic?

These are designed for a true plug-and-play experience. Because they are a wireless, "all-in-one" design, most users can complete the installation in under 3 minutes by simply swapping the old bulbs for the new 9004 LED headlight bulbs.
