Brightness: 3057 Vs. 3157
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 of 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 2000 to 10000 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 the bulbs. You can get both halogen and incandescent varieties for both the 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.
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.
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 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 the 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 is that it is clear.
Differences between the 3057 and the 3157 Bulb
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, turn signal, parking, and back-up light. However, only the 3157 can work with the day time running light bulb. They vary in length, where 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.
