As you can see from the table, there are some notable differences between the 3057 and 3157 bulbs.
What is the 3057 Bulb Used For?
The 3057 bulb is compatible with many car light types, including backup lights, brake lights, parking lights, taillights, and turn signals. It has a relatively long lifespan of 1200 to 5000 hours and a low intensity, making it ideal for the rear part of the vehicle.
While it is commonly used in automobiles, the 3057 bulb can also be found in marine technology, aircraft, and railroad equipment. When looking for a 3057 bulb, it’s essential to choose a high-quality one like the SYLVANIA 3057 long-life bulbs, which are designed to withstand road shock and vibrations, resulting in a longer lifespan.
What is the 3157 Bulb Used For?
The 3157 bulb is similar to the 3057 bulb in terms of functionality, but it can also be used as a daytime running light. It is brighter than the 3057 bulb and has a longer lifespan of 2000 to 10000 hours.
When looking for a 3157 bulb, it’s important to choose a high-quality one like the Philips 3157 longer-life bulb, which offers twice the life of standard bulbs and reliable performance due to its sturdy filament and gas mixture.
Differences Between the 3057 and 3157 Bulb
While the 3057 and 3157 bulbs have similarities, there are some differences that set them apart. Here are some of the key differences:
- Brightness: The 3157 bulb is brighter than the 3057 bulb, with a candle power of 32/3 compared to the 3057’s 32/2.
- Electricity consumption: The 3157 bulb uses more energy at 26.9 watts compared to the 3057 at 26.88 watts.
- Application: Both bulbs can be used for car lights like taillights, brake lights, parking lights, turn signals, and backup lights. However, only the 3157 bulb can be used as a daytime running light.
- Length: The 3157 bulb is shorter at 1.25 inches compared to the 3057’s 2.09 inches.
- Lifespan: The 3157 bulb has a longer lifespan of 2000 to 10000 hours compared to the 3057’s 1200 to 5000 hours.
- Type: The 3157 bulb is incandescent, while the 3057 bulb is halogen.
Which is Better: 3057 or 3157?
When it comes to choosing between the 3057 and 3157 bulbs, it ultimately depends on your preferences. The 3157 bulb is brighter, has a longer lifespan, and can be used as a daytime running light. However, the 3057 bulb is more power efficient, which may be a factor to consider if you’re concerned about battery power consumption.
In terms of brightness, the 3157 bulb is the clear winner with a candle power rating of 32/3 compared to the 3057’s 32/2. It also produces more light using the same current as the 3057 bulb, making it a popular choice for daytime running lights.
