2057 Vs. 1157 Bulb – Differences and Similarities

2057 and 1157 are both popular types of car bulbs. They are similar in that they are both used for tail lights, brake lights, and turn signals. They are different in that 2057 bulbs are slightly longer and have a different base. 1157 bulbs are also a bit brighter.

1157 bulb

The 1157 bulb is a type of incandescent light bulb. It is often used in automotive applications, such as tail lights and brake lights. The 1157 bulb is also used in some types of flashlights.

The 1157 bulb has a two-filament design. One filament is used for low-beam applications and the other is used for high-beam applications. The two filaments are not connected and are not used at the same time.

The 1157 bulb is not as common as it once was. It has been replaced by more efficient bulbs, such as LED bulbs.

2057 Vs 1157 Differences

There are a few key differences between 2057 and 1157 bulbs. For starters, 2057 bulbs are slightly longer, which means they may not fit in all applications that 1157 bulbs are used in. Additionally, 2057 bulbs produce slightly more light than 1157 bulbs. Finally, 2057 bulbs have a slightly different connector than 1157 bulbs, so they are not compatible with all 1157 sockets.


Both the 2057 and 1157 bulbs are incredibly bright, but there are some differences in how they produce light. The 2057 bulb uses a halogen gas filled capsule that is heated by an electric current. This produces a very bright, white light. The 1157 bulb uses a filament that is heated by an electric current. This produces a less bright, yellowish light.

Assuming you are referring to the difference between 2057 and 1157 bulbs in automotive lighting:

The 1157 bulb is a dual filament, meaning it has two different light outputs: one for running/tail lights, and one for brake/turn signals. The 2057 bulb is a single filament bulb, meaning it only has one light output. The 2057 is used as a turn signal, while the 1157 is used as a brake light.

As for wiring, the 1157 bulb has two wires: one for the running/tail light filament, and one for the brake/turn signal filament. The 2057 bulb only has one wire, since it only has one filament. When wiring a 1157 bulb, you will need to connect the running light wire to the running light circuit, and the brake/turn signal wire to the brake/turn signal circuit. For a 2057 bulb, you will only need to connect the wire to the turn signal circuit.

Power Consumption

The 1157 bulb consumes less power than the 2057 bulb. The 2057 bulb draws more power and produces more light than the 1157 bulb.


There are several key differences between 2057 and 1157 bulbs that can impact longevity. 2057 bulbs tend to have a longer lifespan due to their higher quality construction and materials. They also have a higher voltage rating, which means they can handle more power and heat without burning out. However, 1157 bulbs are less expensive and more widely available, so they may be a better option for some applications. Ultimately, the decision between 2057 and 1157 bulbs depends on the specific needs and preferences of the user.
