HID bulbs with a lifespan five times that of halogen bulbs, achieving a 300% increase in brightness. - Model: 9006-6000K - Type: HID (High-Intensity Discharge Lamp) - Features: 300% brightness increase (compared to halogen bulbs) - Lifespan: Over 2500 hours (5 times that of halogen bulbs) - Material: UV block quartz This is an item for sale. The person who purchased it obtained it to install in a Prius, but for some reason, they never installed it and kept it in storage. They no longer need it because they changed cars, so they asked me to sell it. I don't know the details, so please make your own judgment. If you have any questions, please comment. Thank you for viewing.
