These bulbs are engineered for 12V and 24V systems, rely on a constant-current IC for stable output, and use an aviation-grade aluminum body to disperse heat. They are suitable for many 3157\/3156-style bases and designed to improve visibility when backing up or signaling in challenging driving conditions.\u003c\/p\u003e\n\n\u003ch3\u003eHow much brighter are these bulbs compared with standard halogen reverse lights?\u003c\/h3\u003e\n\u003cp\u003eThese SEALIGHT LEDs claim up to 700% greater perceived brightness than typical halogen bulbs, achieved by combining a high-density SMD array with a projection lens that directs the beam.
