3057 Vs. 3157 Bulbs – What’s The Differences?

The car lighting system is very diverse and requires different light bulbs to perform different functions. When looking for an ideal bulb for a particular section, let’s say the braking light, you have to look at specifications like brightness.

The 3057 and 3157 light bulbs are among the common ones in the automotive industry and may confuse many people as they are used interchangeably.

In a bid to understand their differences, we bring you the 3057 vs. 3157 debate to give you a better understanding of each.

What Are 3057 Bulbs?

The 3057 bulb is a versatile and commonly used dual-filament bulb that is mostly used for brake lights, taillights, and turn signals.

The 3057 is a popular choice for standard-duty applications due to its compatibility with a wide range of vehicles. It provides reliable performance when moderate brightness is sufficient.

What Are 3157 Bulbs?

The 3157 bulb, on the other hand, has the same characteristics but stands out due to its increased brightness and durability.

It is designed specifically for applications that demand better visibility and performance under more demanding circumstances. The 3157 bulb is perfect for cars that prioritize efficiency and safety.

What Is The 3057 Bulb Used For?

The 3057 bulb works as a backup bulb and a braking bulb, parking bulb, and turn signal bulb when it comes to vehicle lights. Compared to the frontal region for headlights and fog lights, this light has a lower intensity but is not entirely dim.

It makes it ideal for the vehicle’s back end. A long lifespan of 1200–5000 hours is combined with a high intensity to make this bulb ideal for use on downtown streets.

While it is widely used in cars, 3057 may also be found in maritime technology, aviation, and railway equipment. To get the most refined illumination, you will want to look for the best 3057 bulbs on the market, which are available for purchase.

What Is The 3157 Bulb Used For?

When it comes to functionality, the 3157 bulb is quite similar to the 3057, which may be used for the brake light, taillights, parking lights, and turn signal lights, among other things.

The primary distinction is that 3157 may be used as both a running light and a daytime running light, depending on your needs. With a lifespan ranging from 2000 to 10000 hours, this bulb outshines the competition in terms of brightness and cost.

If you are looking for the finest 3157 light bulb, you can be confident that you will get excellent usages and will be in full compliance with local traffic regulations.

Differences between the 3057 and the 3157 Bulb

3057 Vs. 3157 Bulbs

The peak of the debate between the two light bulbs comes to play when you look at their differences. A difference you can note is the brightness, where the 3157 bulb is brighter. It has a candle power of 32/3 compared to the 3057’s 32/2.

They also vary in electricity consumption, where the 3157 seems to use more energy at 26.9 watts. This is not far from the other bulb, which consumes 26.88 watts.

Another area of variance is the application. You can use either of the bulbs for car lights like taillights, brake lights,  parking, turn signal, and backup light.

However, only the 3157 can work with the daytime running light bulb. They vary in length, whereas the 3157 is shorter at 1.25 inches.

The two bulbs also differ when you look at their life, with the 3157 being more durable, with a life of 2000 to 10000 hours, longer than the 3057’s 1200 to 5000 hours. The 3157 bulb is incandescent, and the other is a halogen light.

So, 3057 vs. 3157, which is the best? When looking at the difference between the two light bulbs, you can get the best depending on your preferences. The 3157 seems the best as you can use it in various applications, it has a long life and also produces more light.

The 3057 is also bright, but not to the extent of the other light. It has a low wattage, which you might see as a hint at low car battery power consumption. However, the two do not differ much, with a variation of roughly 1 unit.

#1. Brightness.

Brightness is an essential factor to look at when getting a light bulb, where it should provide enough illumination to ensure all road users’ safety.

When looking at this attribute, the 3157 bulb is the brighter of the two, with a candle power rating of 32/3, compared to the 3057’s 32/2. The 3157 also produces more light using the same current as 3057.

It is for its brightness that it is most probably used in daytime running lights. Both the two light bulbs have a decently lengthy life, with the 3057 having a life range from 1200 to 5000 hours.

The 3157 is more durable and lasts between 2,000 to 10,000 hours, meaning it is very durable. The bulbs are great for city lights, especially when used for brake lights or taillights. Bulb technology is another area to look at to understand bulbs.

You can get both halogen and incandescent varieties for both two bulb types. The halogen variety is the most efficient, as it consumes little energy but produces more light.

They are also long-lasting. You should also note that the 3157 consumes more current than the 3057, with a wattage of 26.9/8.3, compared to the latter with 26.88/6.72.

#2. Lifespan.

The lifespan of automotive bulbs, such as the 3057 and 3157, can be influenced by various factors. Prominently factors include usage conditions, frequency of use, manufacturing quality, and design. While specific lifespans can vary, here is a general idea:

Typically the lifespan of a 3057 bulb ranges, from 1200 to 5000 hours when used regularly. On the hand, a 3157 bulb is expected to last around 2000 to 10,000 hours with usage.

#3. Size.

As earlier hinted, sometimes, you can use the two bulbs interchangeably as they have a similar plastic DF base. However, there might be some variations when you look at their sizes. The sizing looks at their diameter and length.

The two are miniature bulbs and have an S-8 shape. The difference comes in their length, where the 3157 seems smaller at 1.25 inches, compared to the 3057’s 2.09 inches.

They have a similar diameter of 1 inch. With a similar wedge DF base, you can use them in place of the other, as they can fit into their respective sockets.

#4. Full specs.

As a mechanic seeking to understand the debate between the two bulbs, you should understand their full specs.

Despite their similarities, they have several differences that make them different from each other. Let us look at some of the specs of each of the two bulbs.

The 3057 specs

The 3057 has a clear bulb finish and uses halogen technology. It has a plastic wedge DF base, a similar one to the 3157’s. It has a voltage rating of 12.8/14.0 volts and a wattage of 26.88, which is quite lower than that of the other bulb.

You cannot overlook its brightness, which is an essential point that differentiates the two bulbs. The 3057 has a candle power of 32/2, a lower value compared to the 3157.

The 3157 Specs

The 3157 also sports a clear bulb finish with an S-8 shape and has a double filament like the other bulb. It also has a plastic wedge base, one of the reasons you can use it in place of the 3057 bulbs.

Whereas the former is a halogen bulb, the latter is an incandescent bulb. However, you should understand that halogen bulbs fall under the incandescent bulb class; the main difference is that they feature an envelope of inert gases and a halogen such as iodine. Another similar spec that the 3157 shares with the 3057 are that it is clear.

#5. The Level Of Durability.

It has been estimated that the average rated life span in 3157 is greater than that of the other one( 3057). Thus, the 3157 is more long-lasting than the 3057. A lightbulb’s lifespan is highly dependent on the manner in which the driver utilizes it in his cars.

Furthermore, research has shown that the life spans of both the 3057 and 3157 bulbs may vary from 1200 to 5000 hours, respectively. As can be seen, a bulb’s lifespan varies widely depending on the vehicle’s state and how it is utilized.

Pros And Cons Of The 3057 And 3157 Bulbs

#1. 3057 bulbs.

Benefits

  • 3057 bulbs have a wide field of vision and energy saving.
