All about LED lighting for ALFA ROMEO 166

Are you looking for LED bulbs for your Alfa Romeo 166? This high-end model, produced from 1998 to 2007, deserves lighting that matches its status. At AGM Vision, we offer a complete selection of LED bulbs compatible with all types of headlights on the 166.

For the low beam headlights, your Alfa Romeo 166 can be equipped with three different technologies depending on the version: H7 bulbs for halogen headlights, D2S for xenon headlights, or D1S for bi-xenon headlights. The high beam headlights use HB3 bulbs, while the front fog lights operate with H3. The front sidelights and interior lighting are H6W, the license plate is W5W, and the dome light is C10W.

As the Alfa Romeo 166 is equipped with a CANbus system, it is essential to choose LED bulbs with an integrated anti-error module in order to avoid warning messages on the dashboard. Our CANbus-compatible LEDs guarantee a hassle-free installation and optimal operation.

Whether you want to improve the visibility of your low beams, modernize your sidelights, or enhance the lighting of your license plate, AGM Vision supports you with high-performance LEDs suited to each location on your Alfa Romeo 166.
