This comprehensive LED interior light kit includes thirteen bulbs designed to replace dim factory lighting in most 12-volt vehicles. The set contains three bulb types: five T10 bulbs with 5050 LED chips producing 60 lumens, four T10 bulbs with 1206 LED chips producing 56 lumens, and four 31mm festoon bulbs with 2835 LED chips producing 84 lumens. All bulbs emit a bright 6000K white light to illuminate your vehicle's interior clearly and efficiently. Each bulb combines premium LED chip technology with optimized circuit design for low power consumption and an extended lifespan of up to 50,000 hours. Installation is straightforward and requires no modifications, as these LED bulbs directly replace original T10 and 31mm halogen bulbs. Use them for dome lights, map lights, license plate lights, trunk lights, and side positioning lights to refresh your vehicle's interior lighting.
