HID and LED Product Installation Guides
Find installation PDFs, wiring diagrams, and product reference images for popular HID conversion kits, LED forward bulbs, relays, ballasts, and harnesses carried by BRI Source.
Install guides are supplemental reference material. Always confirm the exact product version, bulb size, vehicle wiring, and headlight package before installing. Some vehicles may require relays, decoders, CANBUS modules, anti-flicker modules, or professional diagnosis.
Disconnect power before wiring work, avoid modifying factory wiring unless you know the circuit, and contact BRI Source before ordering or installing if you are unsure which setup applies to your vehicle.
