For all practical purposes, they are interchangeable. To my eye the 3357 seeems to be brighter on the heavier filament. (brake/turn)
The 3157 is a clear bulb and the 3157NA is an amber color.
3157 is the bulb type, the "K" means the bulb is filled with the inert gas Krypton.
If you are looking to use the new energy efficient light bulbs on a light dimmer you will need to buy specially made dimmable CFLs. Not all energy efficient light bulbs are compatible with dimmers so be sure to check the packaging for information.
They are known as CFL bulbs. It stands for Compact Fluorescent Lamps.
why light bulbs are fragile
The 3157 is a clear bulb and the 3157NA is an amber color.
The primary difference between 3157 and 3157NA bulbs lies in their design for specific applications. The 3157 bulb is a dual-filament bulb commonly used for brake lights and turn signals, while the 3157NA (NA stands for "natural amber") is designed for use in applications where an amber light is needed, such as turn signals on vehicles. The 3157NA typically emits an amber light, whereas the standard 3157 can produce white or red light depending on the specific application.
I have successfully installed bulbs 3057, 3157 and 3457 in my Chrysler Town & Country mini-van, for the brake/stop lights.
Yes, the T3157 and the 3157 bulbs are compatible. The "T" in T3157 refers to the bulb's base type, indicating it's a twist-lock bulb, while the 3157 designation is the standard for the bulb's size and function. Both bulbs often serve similar applications in automotive lighting, but it’s always best to check the specific requirements of your vehicle or fixture to ensure proper fit and function.
Well. I work at NAPA and it called for a 3057kx which we naturally don't have in stock. But when the customer pulled the bulb out it was a 3157. which will fit in its place. It might be some sort of long life bulb. Just put a 3157 in there. that's what most brake lights are.
The 3157 and A4114 bulbs are not directly compatible as they have different bases and electrical specifications. The 3157 bulb typically has a dual filament and is used for taillights and turn signals, while the A4114 is a specific type of wedge base bulb often used in other applications. Always check the vehicle's manual or the socket type to ensure compatibility before replacement.
The 1157 has a 15mm metal bayonet (push/twist) cap, while the 3157 has a plastic wedge (push-in) cap.
Yes, the 4157 is just slightly more powerful than the 3157, 28.5w compared to 27w

Yes, they more or less are. Both have two filaments, one for the parking light, and one for the brake light or turn signal. The parking light filament of the 3157 is a little brighter than the parking light filament of the 3057. The signal filaments of both bulbs are the same brightness.
The primary difference between 3157 and 3157KX bulbs lies in their brightness and application. The 3157KX is typically a higher-output version of the standard 3157 bulb, designed to provide increased light output and enhanced visibility. Both bulbs have the same base and fitment, but the 3157KX is often used in situations where brighter lighting is needed, such as in brake lights or turn signals. Always check compatibility with your vehicle before replacing bulbs.
