High-capacity relay designed to protect your brake light switch from premature failure due to excessive current draw. Required when running halogen brake bulbs, more than three brake lights, or trailer lighting. This relay diverts the high-amp load away from the brake switch, significantly increasing its life and reliability.

Essential for high-output lighting setups where current draw exceeds what a standard brake switch can handle.
