harness allows you to bypass the HID system entirely and upgrade to reliable LED bulbs.By using this adapter, your factory
headlight switch will send 12V power straight to the new 9006/HB4 LED bulbs, and you can completely remove or unplug the old 
round aluminum HID ballast and its braided metal igniter cable.

(often interchangeable with the DDLT002 or DDLT003),Common Part Numbers: 85967-22080, 85967-45010, 81107-75020,85967-08020
