3057 Vs. 3157: Major Differences Explained

In this section, we have broken down the 3157 vs. 3057 debate to understand each side better to help you decide which bulb is best for your vehicle.


These bulbs are similar to each other in many ways. They both share the same shape and size. However, there is one major difference that separates them - the ability to produce light.

One noticeable difference is the brightness of the bulbs. 3157 is more vibrant. Comparatively, it has 32/3 candle power, whereas the 3057 has 32/2 candle power. The difference between them is that the 3157 bulb is more vibrant and has a higher brightness level.

In addition to producing more light, the 3157 also consumes less current than the 3057. This is because it has a greater area of flowing light and a smaller area of "hot spots," which consume more energy.

The term "running lights" refers to the lights mounted on the front of utility vehicles, such as cars or trucks. Many drivers use them to make their vehicles more visible during daylight hours.
Due to its brightness, it is most likely used to light up running lights during the day. That being said, these two light bulbs last a decent amount of time.

Power Consumption

Light bulbs are an important part of our daily lives. We use them to provide light in the home, at work, or when we need to see in low-light conditions.

Did you know that there is also a difference in the electricity consumption between them, with the 3157-bulb consuming 26.9 watts, which is more than the 3057 bulbs?

There isn't too much difference between this and the other bulb, which consumes 26.88 watts. Both bulbs will save energy, cost less in the long run, and last for a number of years.


There are also differences in the application. The 3157 bulb is a multiple-purpose bulb used in cars. It can be used as a backup light, brake light or turn signal light.

In fact, either bulb can be used for car lights, including tail lights, brake lights, park lights, turn signals, and backup lights. However, the 3157 bulb is the only one that can be used in daylight.
Its innovative design has created a huge demand for this energy-efficient bulb. It gives off a pleasant, warm white light without emitting heat, making it perfect for other applications in the automotive industry.


If you look at their sizes, there may be some differences. Sometimes buying the wrong size light can be a hassle. For example, the 3157 is shorter at 1.25 inches. These two bulbs often have the same plastic DF base, so you can use them interchangeably.

Their diameter and length are measured for size. This bulb is miniature and has an S-8 shape. A difference in length is apparent between the 3157 and the 3057, where the 3157 measures 1.25 inches versus 2.09 inches.

Similar in diameter, they both measure 1 inch. Since they can fit into their respective sockets, you can use one in place of the other if they have similar wedge DF bases.


A 3157 bulb is the more commonly used type of light bulb for cars. It offers a longer lifespan rated for 2000 to 10000 hours than the 3057's 1200 to 5000 hours. In addition to being great for city lights, these bulbs can also be used for brake lights or taillights.

These bulbs make a great addition to any car because of their longevity. They're durable, energy-efficient, and can last up to 20 years. In addition, they're easy to install with just a single wire running from the starter.

Bulb Technology

To better understand bulbs, we should examine bulb technology. Both types of bulbs are available in incandescent and halogen varieties.

Incandescent light bulbs have been around for a long time. In recent years, incandescent light bulbs have been slowly being phased out in favor of more energy-efficient halogen lamps. Halogen bulbs are also available in a variety of shapes and sizes, each with a different form factor.

Compared to other types of bulbs, halogen bulbs are the most efficient because they consume less energy but produce more light. Halogen bulbs also have a long lifespan and are very durable.

Which One Is Best?

The 3157 vs. 3057 is one of the most popular car light bulb questions. When you're in the market for a set of tail lights, you'll find that these are two main types of bulbs available to choose from.
