Last month, some people sent me a message to ask about the difference and similarities between the 3057 and 3157 bulbs. So in this article, I will tell you what I know about them.
Dim filaments are the mostly difference between 3057 vs. 3157. The 3157 bulbs have more than 32/3cp dim filament, whereas the 3057 bulbs have only 32/2cp dim filament. But, other than these, they are pretty similar with dual filament bulbs and wedge D.F bases.
For more understanding, let’s read below details comparison
Main Difference Between 3057 and 3157
These two bulbs are most common for car lighting systems. However, it is necessary to know how they are different when you need to replace them.
Brightness: 3057 vs 3157
The 3157 bulb emits brighter light than the 3057. 3157 bulb produces more current but using the same amount of voltage of 3057. Thus, the brightness of 3157 is 32/3cp, whereas 3057 has 32/2cp brightness. It is because of the brightness that 3157 bulbs are best in daytime running lights. In addition, the 3157 is brighter than the 3057 in the case of parking lights. But, for brake signals and turn signal lights, the brightness is the same for both of them.
Moreover, brightness is an essential factor while getting a bulb. Furthermore, it’s crucial to ensure that it provides enough illumination and road user’s safety.
Lifespan: 3057 vs 3157
The average lifespan of 3157 is longer than that of 3057. However, in my opinion, the life of a bulb depends on how you use it in your car.
Durability: 3057 vs 3157
Both the light bulbs have a decent lengthy life. The 3157 is comparatively more durable and lasts between 2000 to 10,000 hours. In contrast, the 3057 bulb has a life range from 1200 to 5000 hours. Moreover, In my experience, durability depends on vehicle condition and bulb usage.
Energy usage: 3057 vs 3157
The 3157 bulb uses comparatively more energy than the 3057 bulbs. Moreover, the 3057 bulb uses 6.72 watts, whereas the 3157 uses 8.3 watts. Thus, with more current and power, between the 3057 vs 3157 bulbs, the 3157 emits brighter light. Moreover, 3057 bulbs produce 2.1/0.48 ampere, whereas 3157 produces 2.1/5.93 ampere current.
Cost: 3057 vs 3157
Depending on brands, the cost of the 3157 bulbs ranges from $5 to $5.3, whereas for 3057, it ranges from $5.3 to $8. Thus, between 3057 vs 3157, the cost of the 3157 is comparatively low. Moreover, you may choose 3157 over 3057 as it is cost-efficient along with high performance.

3057 vs 3157: Similarities
Despite the differences, there are some similarities between these two 3057 and 3157 bulbs.
The 3057 bulbs and 3157 bulbs have the same dual filament and C-6 class . Moreover, both bulbs have 32 candlepower bright filaments.
Both the 3057 and 3157 bulbs use energy on the same voltage. In addition, they run on 12.8/14 voltage. Moreover, both bulbs are reversible as they have the same circuitry.
Both the 3057 and 3157 bulbs have the same wedge D.F fittings for mounting in most car lighting systems. So, you may install both of them in the same holder and are interchangeable. However, you may look at their sizes as sometimes there is a difference in their length. In some cases, the 3157 seems smaller at 1.25 inches than 3057 with 2.09 inches. Moreover, with similarities in wedge base mounting, you can use them in place of each other. Furthermore, they fit well in their respective sockets. There is another reason making them capable of interchanging as they have the same circuitry and reversible bulbs.
Both of the 3057 and 3157 bulbs have the same dimension. They both have a 1-inch diameter and 2.1 inches in length. However, in some variants, there may be a difference in their height. Moreover, in some designs, the 3157 may be smaller at 1.25 inches to 3057 with 2.09 inches.
Both 3057 and 3157 bulbs have the same S-8 bulb shape. Moreover, they come with a wedge D.F mounting base. Therefore, they are easily interchangeable.
