Designed for an easy 1:1 swap, the bulbs include a smart IC driver and aviation-grade aluminum body to manage heat, reduce compatibility errors, and extend lifespan. They are sold as a pack of two and aim to improve visibility and presence when reversing without complicated rewiring.\u003c\/p\u003e\n\n\u003ch3\u003eHow much brighter are these bulbs compared to stock halogen reverse lights?\u003c\/h3\u003e\n\u003cp\u003eThese AUTOONE LEDs use 5th generation chips and a multi-SMD layout to produce substantially more usable light than factory halogen bulbs.
