Replacement H4 Xenon Bulb 5000K 35W

Replacement H4 bulb — reliable lighting via aftermarket ballast

This quality replacement H4 bulb is designed exclusively for connection to aftermarket xenon or LED ballasts, i.e. transformers. It is an ideal spare or replacement part when one bulb on your existing aftermarket set burns out.

The bulb provides a strong and clear light beam while retaining the combined low and high beam function on an H4 socket. With standard connectors for external drivers and ballasts, it allows you to quickly and easily replace the part without modifying the wiring.

Please note that this bulb cannot work by direct connection to the factory 12V jack of a car — it necessarily requires an external ballast. The package contains one bulb.
