IAP Headlight Wiring Upgrade Kits

IAP's exclusive wiring upgrade kits make it easy to get maximum performance from your headlights. Designed by our staff, our kits work with both 2 and 4 headlight 12v negative ground systems found on Alfa, Fiat and Lancia models.

Designed with 16-gauge wiring and integrated fuses and relays, our kits install easily and do not require the removal of your existing wiring system. By eliminating bad grounds and creating a more direct current, these ultra-efficient kits dramatically improve your headlight performance--especially if you've upgraded to halogen bulbs.

These "plug and play" systems are easy to install, using basic tools and the included instructions.

The 2 headlight kit fits 1960-1994 Alfa Spiders, 1968-1985 Fiat Spiders and most other two-headlight models.

The 4 headlight kit fits 1981-1986 GTV6, 1975-1980 Alfetta, 70-77 Montreal, 69-74 Berlina, 71-75 Fiat Coupes, Wagons, & Sedans, 71-77 Fiat 131, and 75-82 Lancia Beta and Zagato models.
