The primary difference between a 3157 LCP bulb and a 3157 K bulb lies in their design and intended use. The 3157 LCP (Long Life, Clear, and Plug) bulb typically offers a longer lifespan and is designed for general lighting applications, while the 3157 K bulb is a type that may have a specific application, such as enhanced brightness or a specific color temperature. Both bulbs fit the same socket but can differ in performance characteristics like brightness, color, and durability. Always check the specifications to ensure compatibility with your vehicle or application.
I'm not aware of a .45 Magnum. There is a .44 Magnum. The 44 magnum is typically a revolver round, very high power. The 45 ACP is typically used in semi-automatic pistols. The 45 ACP is not as powerful compared to the 44 magnum (mostly due to the amount of propellant in the 44 magnum compared to the 45 acp).
There isn't a .40 ACP - the cartridge you're thinking is the .40 S&W. Basically, it's a larger cartridge than the 9mm, being essentially a shortened version of the 10mm auto cartridge.
