Setup, Compatibility & Care
To ensure optimal performance, verify that your vehicle uses the HB4/9006 fitting type before purchase. When installing, always handle the bulb by its plastic base; avoid touching the glass directly with bare fingers, as oils from the skin can create hot spots on the quartz glass, significantly reducing the bulb's service life. Ensure the light switch is off and the engine is cool before attempting installation. If you are replacing a burnt-out bulb, it is highly recommended to replace both the driver-side and passenger-side bulbs simultaneously. This prevents uneven light intensity and pattern divergence, which can affect your depth perception while driving.
