3157k Bulb vs 3057k Bulb: What's The Difference?

3157k Bulb vs 3057k Bulb: What’s The Difference?


May 9, 2022

Some beginners contacted me last month to ask about the distinctions and parallels between the 3057k and 3157k bulbs. So in this post, I’ll share what I know about them.

The most significant difference between 3057 and 3157 is the dim filament.

The 3157 bulbs have a greater number of 32/3cp dim filaments than the 3057 bulbs, which only have 32/2cp dim filaments. However, except for these features, they are quite similar to dual filament bulbs and wedge D.F bases.

Let’s look at the differences between these two technologies in greater detail. For further comprehension, let’s examine the following information:

The Differences Between 3057k And 3157k Bulb

3057k And 3157k Bulb

The most frequent bulbs used in automobile lighting systems are these two. However, when it comes to changing them, you need to be aware of their differences.

Brightness Comparison of 3057 vs 3157

The 3157 light bulb is brighter than the 3057 because it produces more current but uses the same amount of voltage. Because 3157 generates more current but consumes the same amount of voltage, its brightness is 32/3cp as opposed to 3057’s 32/2cp.

3157 bulbs are the greatest choice for daytime running lights since they produce brilliant light. In the case of parking lights, the 3157 is brighter than the 3057. Both of them, however, have the same amount of brightness when it comes to brake signals and turn signal indicators.

Furthermore, the brightness of a light source is important. Furthermore, it’s critical to make sure it provides enough illumination and safety for road users.

Lifespan Comparison Of 3057 vs 3157

The average lifetime of 3157 is greater than that of 3057. However, in my opinion, the life of a bulb is determined by how you utilize it in your automobile.

Durability Comparison Of 3057 vs 3157

common use of 3057 bulb type

Both bulbs have a decent length of time before they need to be replaced. The 3157 is considerably more sturdy and lasts between 2000 and 10,000 hours.

In contrast, the 3057 bulb has a lifespan range of 1200 to 5000 hours. Furthermore, in my experience, bulb usage and vehicle condition have a significant influence on durability.

Energy usage Comparison Of 3057 vs 3157

The 3157 bulb consumes significantly more energy than the 3057 bulbs. In addition, the 3057 bulb consumes 6.72 watts while the 3157 consumes 8.3 watts.

As a result, the 3057 vs 3157 bulbs utilize comparable current and power. Furthermore, the 3057 bulbs produce 2.1/0.48 amperes of current, whereas 3157 generates 2.1/5.93 amperes.

Cost Comparison Of 3057 vs 3157

The cost of the 3157 bulbs varies from $5 to $5.3, whereas the cost of 3057 ranges from $5.3 to $8.

As a result, between 3057 and 3157, the costs are relatively cheap. Furthermore, you might go for 3157 instead of 3057 since it is more cost-effective while providing equivalent performance.

Use of 3057 and 3157?

Miniature LEDs are common in the automobile industry.


The 3057 bulb is perfect for backup lights, brake lights, parking lights, taillights, and turn signal illumination. Furthermore, this light has a long lifespan of 1200 to 5000 hours and can be used on city streets.

This bulb also interacts with its brightness. In my experience, after so many 3057 bulbs, you must select the best light output bulb. Furthermore, it’s perfect for your car’s rear end since it includes low-intensity lighting.


You may use these 3157 bulbs for the taillight, brake light, parking light, and turning signal light. You can also utilize it as a daytime running light because of its brightness.

Furthermore, this bulb provides the finest service and guarantees that you follow all local traffic regulations. Due to the robust filament and gas combination, you may use these over others to guarantee dependable performance.

What Are The Differences Between Incandescent Bulbs And LED Bulbs?

Incandescent Bulbs Review

Incandescent bulbs are the most popular lighting systems used in these displays. However, it’s important to know which one is the best option when you want to replace your lights.

Incandescent bulbs


  • Lower initial cost due to lower starting price
  • Brightness can be more easily adjusted
  • Warm color
  • It is simple to put up
  • In poor light, there is a greater chance of penetration
  • Provides a better lighting effect
  • Low maintenance


  • It consumes less electricity
  • Heat production is high
  • A lumen per watt ratio of 5 to 20 lumens per watt is low
  • Shorter Lifespan
  • Lower color temperature

LED bulbs

LED bulbs


  • More efficient
  • For an extended period, the battery will last
  • Less energy
  • The light that is brighter and whiter
  • Lights that you can adjust
  • Durable


  • Pricy
  • It’s difficult to set up
  • An add-on


To sum up the distinctions and similarities between 3057 and 3157, you may notice that they differ in brightness and longevity.

Both have features in common, such as shape and size, thus they can be interchanged. You can also utilize these bulbs for tail lights, brake lights, parking lamps, and turn signal lights.

Furthermore, bulb 3157 allows you to use it in daytime running light bulbs. In addition, you now know how to differentiate between incandescent and LED bulbs. Furthermore, you’ll learn about the significance of K, which is often referred to as “Krypton.”
