Tired of dim, yellowish interior lights in your car? Upgrade to these bright white Qasim LED bulbs. This pack comes with six 44mm (that's 1.73 inch) festoon-style bulbs that are a direct replacement for super common numbers like 561, 562, 567, 211-2, 212-2, and a bunch more. They run on your car's standard 12V system, put out a crisp white light (6500-8000K color temp), and are way brighter than old halogen bulbs. They're waterproof (IP65 rated) and use 5050 LED chips for good output. Perfect for your dome light, map lights, trunk light, glove box, and especially your license plate lights for a cleaner look. Installation is the easiest part – just pull out the old bulb and plug this one in. No wiring changes needed. They're energy-efficient, run cool, and should last ages. One less thing to worry about. The 6-pack is great because you can do all your interior lights at once and probably have spares.
