Upgrade your car's lighting with these bright red T10 LED bulbs! This 50-pack gives you plenty of bulbs to replace all those dim halogen lights throughout your vehicle. Each bulb pumps out 120 lumens of vibrant red light using five 5050 SMD chips arranged for 360-degree illumination. They're designed to work with 12V systems only, so perfect for cars, trucks, motorcycles - basically any vehicle. The cool thing is they're direct replacements for so many bulb types: 194, 192, W5W, 168, 2825, and about twenty other number codes. I used these for my map lights, dome light, side markers, and license plate lights - the red color gives everything a cool custom look, especially at night. Installation is straightforward but remember: LEDs have polarity, so if a bulb doesn't light up at first, just flip it 180 degrees and try again. They draw only 0.8 watts each, so way more efficient than old halogens, and they light up instantly with no delay. The built-in current limiting resistor prevents hot spots and extends the bulb life. At about 2.7cm long and 1.1cm diameter, they fit perfectly in all the standard sockets. The red color is consistent across all bulbs in the package, and they come with a one-year warranty for peace of mind. Great for DIY enthusiasts wanting to customize their ride without breaking the bank!
