How long do led headlights last?

Want to know how long do LED headlights to last? If they’re in a housing designed for these bulbs, and they have an adequate heat sink, they can last up to 50,000 hours. For comparison, a halogen bulb only lasts around 500 hours. That means you’ll never need to replace the lights in a modern LED headlight or taillight as long as you own the vehicle.
LED bulbs that work in standard halogen fittings aren’t in an ideal environment, requiring a less than adequate heat sink to fit in the enclosure. Quality bulbs only last around 8,000 hours, which is still far longer than its halogen equivalent.
