This color temperature mimics natural daylight, providing clear, true-to-life illumination that makes details easier to see—whether you're searching for lost items in your car's glove box, checking food expiration dates in the fridge, or navigating your camper at night. Unlike warm white bulbs that can make spaces feel dim, these cool white LEDs brighten up interiors without harsh glare, creating a more comfortable environment.The bulbs' dual-base design screw base and bayonet base ensures compatibility with most common light fixtures, eliminating the guesswork of finding the right bulb for each application. The screw base fits perfectly in refrigerator and freezer light sockets, while the bayonet base is ideal for car dome lights, map lights, and puddle light systems. This versatility makes the set a valuable addition to any toolkit, as one pack can address multiple lighting needs around your vehicle, camper, and home.Durability is a key feature of these LED bulbs, starting with their robust plastic housing that resists impacts, vibrations, and temperature fluctuations—critical for vehicle and camper use where roads and travel can cause constant movement. Unlike fragile incandescent bulbs that break easily during installation or travel, these LEDs stand up to rough handling, ensuring reliable performance even in bumpy conditions. The heat-resistant design also prevents overheating, making them safe for enclosed fixtures like fridge compartments and car dome light housings.Energy efficiency is another major advantage, with each bulb consuming just of power while outputting of light—equivalent brightness to a incandescent bulb but using 88% less energy.
