★☆ Converting 2-lamp headlights (H4 etc.) to 4-lamp headlights ☆★ ■ This is a 4-lamp conversion harness kit for H4 (HB2) headlights, originally a 2-lamp system. ■ It converts 2-lamp headlights with Lo/Hi switching (where the Lo beam turns off when the high beam is activated) to a 4-lamp headlight system that illuminates both Lo and Hi beams simultaneously during passing and high beam use. ■ Compatible with any light source: HID, LED, or halogen. ■ Visibility is dramatically improved, and the vehicle will pass inspection even after the 4-lamp conversion. ◆◆◆◆◆ Specifications and Notes ◆◆◆◆◆ ~ Set Contents ~ ■ Conversion harness kit set ※ Installation instructions are not included. ※ This is a general-purpose product for various manufacturers. ※ Not compatible with headlights other than H4. ※ Although new, there may be some scratches or marks on the package or the product itself due to being an imported item. ※ We recommend that installation be done by a professional. ※ Please perform the installation at your own risk. ※ The detailed specifications of the product may be changed without notice.
