R-e-place Only for HID Assembly Bulbs: R-epl-acement for stock D4S hid bulbs only, NOT ADAPT if your auto has stock H-a-logen
350% Brightness: filled with high-purity xenon gas, D4S xenon bulbs are 3.5x brighter than ha-lo-gen bulbs and 2x brighter than standard HID lights. Built-in high voltage starter, braking response time as fast as 3s to start.
3500hrs Longevity: D4S hid bulbs ensure the last 3500hrs lifespan, reducing your bulb r-epl-acement frequency. IP67 waterproof design and high-temperature resistance metal base reduce the fog and vaporization damage caused during driving.
Easy to Install: 1:1 factory HID bulb design optimizes compatibility, you take only 5 minutes to complete the whole re-pl-acement process.
Ways to Check Bulb Size: filter systems may not be 100% correct or up to date as 85% of cars that use HID bulbs also have ha-logen versions. If you are not sure which bulb size your vehicle requires, PLEASE Search "automotive bulb finder" or check if your stock bulbs are HID.
