Headlight Relay 12 Volt Kit - RLK-1

A relay uses a small amount of power to activate in order to provide a much larger amount of power to the headlights. In older cars, headlight relays overcome the problem of thin gauge or corroded wires not being able to carry enough current to the headlights, making them dim.

Our headlight relay kit includes everything you need to upgrade a car or truck with sealed headlamps, including:

• Headlight Relay
• Connectors
• Instructions

The installation instructions in the kit will walk you through adding or replacing the headlight relay. The process requires no special tools and is universal for most cars and trucks, including Ford, Chevy, Hudson, Cadillac, Buick, and more.

This kit is for 12 volt electrical systems and will work for classic cars manufactured after the mid-1950s or antique automobiles that you have converted from 6 volts to 12 volts.
