Main Difference between 3057 and 3157

The major difference between these two types of bulbs is their length, with a 3057 being around 2 inches shorter than a 3157 bulb.

The main reason they’re so different in length is that they have different maximum wattage ratings.

3057 maxes out at 50 watts while a 3157 can go up to 65 watts.

While both bulbs are considered halogen bulbs, they aren’t quite equal since their lengths differ and their max wattages differ as well. There are also some minor differences in how much light they produce, but if you’re going for pure brightness then it doesn’t matter which one you choose.

Both bulbs will produce similar levels of brightness.

It all comes down to whether or not your car has space for longer bulbs or not; if it does then there isn’t much else to consider besides what type of look you want.

If you want more light then get a 3157, otherwise, stick with a 3057. Whichever you choose, be sure to check if it fits before ordering anything!

These bulbs don’t come cheap so it would be a shame to order something that won’t fit your vehicle.

Either way, we hope our guide helped clear things up! Thanks for reading and good luck with finding what you need!

3057

3157

  • Should be handled with care and disposed of safely when their usefulness is over to avoid fire hazards or other safety risks.
  • 3157 (also known as AGC) is an improvement on 3057 that makes it last longer and gives brighter light for its size.
  • It Is compatible with the Philips replacement guide
  • Should be handled with care and disposed of safely when their usefulness is over to avoid fire hazards or other safety risks.
  • 3057 is smaller than 3157, it has four prongs that are shaped like leaves
  • It Is compatible with the Philips replacement guide
  • Both 3057 and 3157 have flat bases but they differ slightly in diameter.
  • While 3157 has six prongs shaped like petals.

What are 3057 and 3157 Used For?

Both 3057 and 3157 bulbs are used as turn signal lights in automobiles, but they also serve slightly different purposes in your car.

The 3057 is a dual filament bulb; meaning that it has two filaments that are held inside of one glass bulb.

When you use your turn signals, only one filament will light up at a time depending on which direction you’re turning.

Your other turn signal light will remain off until you switch directions again.

The 3157 is a single-filament bulb with three wires attached to it.

This means that when you use your turn signals, both filaments will light up at once for greater visibility when turning left or right.

The 3157 bulbs are used primarily in newer cars that have LED taillights.

It doesn’t matter what kind of car you drive, you can always upgrade your turn signal bulbs to brighter ones!

Whether you have 3057s or 3157s now, there are brighter options available for purchase online.

With more lumens per watt than standard halogen bulbs, these upgrades will provide increased visibility and safety while driving at night.

3057 vs. 3157 Bulbs

Incandescent Bulbs vs. LED bulbs

Incandescent bulbs (also called traditional bulbs) are among some of the oldest forms of light technology around.

Incandescent bulbs have been a fixture in homes and businesses since Thomas Edison invented them in 1879.

They come in many shapes and sizes, but each has an electric current that passes through a filament, causing it to heat up until it glows brightly and produces light.

For example, if you’re replacing an incandescent 60W bulb with an LED that only uses 8W of power, it makes sense to invest in a higher quality product that will last longer.

If your local hardware store doesn’t carry high-quality LED bulbs, try looking online at Amazon or other reputable retailers.

Can A 3157 Bulb Replace A 3057?

You might be wondering whether or not a 3157 can replace a 3057 bulb. This is not as easy of a question as it may seem at first glance, because many factors influence which bulb can take the place of another in your vehicle’s lighting system.

First, you must determine if your vehicle’s lighting circuit is 12V or 24V; most modern vehicles use 12V but some older cars and trucks may use 24V systems instead.

Next, you should check your owner’s manual for specifics on what kind of bulbs are recommended for your car or truck.

Finally, once you have determined that a 3157 can indeed replace a 3057 bulb, you should make sure that both bulbs are compatible with each other before purchasing them from an auto parts store.

To do so, simply check their part numbers against one another; they should match exactly.

Can I Use The 3157 Instead Of 4057?

Before we get into any specific details, it’s first important to note that you can use a 3157 in place of a 4057, but not vice versa.

It’s impossible to put a 4057 bulb into a fixture designed for a 3057 bulb and still expect everything to work properly.

In other words, if your car uses a 3157 bulb, you should be able to replace it with another 3157 without issue; however, if your car uses a 4057 bulb and you try to replace it with a 3157 instead, then things will go wrong.

If your current bulbs are working fine (and especially if they’re OEM), then there isn’t any reason to upgrade, the only thing upgrading will do is make your bulbs brighter or give them more features.

What Is The Difference Between 3057 And 3057k?

Many people aren’t aware of it, but there is a difference between 3057 and 3057K bulbs. The K in 3057K bulbs stand for Krypton gas and these are often used as replacements for halogen incandescent lights because they produce less heat and last longer.

While they may cost more, they can be well worth it in terms of long-term performance.

If you have an older vehicle that uses halogen lights, then we recommend using 3057K bulbs instead of their standard counterparts.

These will help your headlights last longer and also provide better illumination when driving at night or during bad weather conditions.

If you want to learn more about these differences, then please keep reading our guide below!

We’ll cover everything from how these two bulbs differ to why you should consider switching over to them today.

After all, once you do switch over, you’ll never look back again!

What Is The Difference Between 3156 And 3157 Bulbs?

The main difference between 3156 and 3157 bulbs is their design.

Most, but not all, car headlight housings use a two-piece bulb with pins that extend from either side of your halogen bulb.

The difference in pin lengths determines what type of light bulb is needed for your vehicle and how it fits into your housing, but both are compatible with about 98% of vehicles on today’s roadways

Can I use a 7443 instead of a 3157?

A common question we get asked is, Can I use a 7443 instead of a 3157? The answer is no.

The G3 sockets are unique to an HID bulb type, whereas incandescent bulbs can fit in either a G2 or G3 socket and will work with any bulb or ballast that specifies it as compatible with either socket type.

Is the 3157 bulb the same as 3157K?

While both may be referred to as 3157 bulbs, these are two different components that have slightly different functions in your vehicle’s lighting system.

Technically speaking, a 3157 light is an actual component of your car’s lighting system, while a 3157K is simply what they call a light bulb that operates on said circuit board.

Are 3157 And 3057 Bulbs Interchangeable?

No, they’re not completely interchangeable.

As our infographic shows, each of these bulbs is unique in its characteristics; even if they seem similar on first inspection, there are features of each that make them distinct from one another.

What does it mean for your car? Well, depending on what you’re using it for and what kind of automobile you have will dictate whether or not either bulb will be a good fit for your vehicle.

Can I Use A 3057 Bulb Instead Of 3157?

It is possible to use a 3057 bulb instead of a 3157 bulb, but it’s not recommended for several reasons.

The main reason is that most manufacturers specify that only their original parts should be used in their vehicles, otherwise there could be major complications down the road such as overheating or not lighting up at all.

So if your car has been working just fine with your current set-up of 3057s, don’t mess with what isn’t broken.
