3157 VS 4157 Bulbs

When it comes to automotive lighting, 3157 and 4157 bulbs are two of the most popular options on the market.

The purpose of this article is to compare and contrast the differences between 3157 and 4157 bulbs for vehicle tail lights. 3157 and 4157 are two types of automotive bulbs used for tail lights that are very similar in appearance and function.

Let’s take a look at the differences between 3157 and 4157 bulbs and how they differ in lifespan, power rating, voltage, colors, vibration resistance and a few other factors.

Differences Between 3157 and 4157 Bulbs

Lifespan

3157 bulbs typically have a lifespan of up to 2,000 hours, while 4157 bulbs have a lifespan of up to 3,000 hours. This means that it takes three times as long for a 4157 bulb to burn out compared to a 3157 bulb.

Power Rating

The power rating for a 3157 bulb is typically 30 watts, while the power rating for a 4157 bulb is typically 35 watts. This means that the 4157 bulb produces more light than the 3157 bulbs.

Gases Used in the Bulb

3157 bulbs use halogen gas, while 4157 bulbs use xenon gas. Halogen gas creates a brighter light than xenon gas, so the 3157 bulb produces a brighter light than the 4157 bulbs.

Voltage

3157 bulbs have a voltage rating of 12.8 volts, while 4157 bulbs have a slightly higher rating of 13.5 volts. This means that 4157 bulbs can handle more power and are better suited for high-performance applications.

Colors

3157 bulbs come in a variety of colors, including white, amber, green, red, and blue. On the other hand, 4157 bulbs only come in red and amber. This makes 4157 bulbs better suited for signaling applications, such as brake lights and turn signals.

Vibration Resistance

3157 bulbs are not designed to withstand much vibration, while 4157 bulbs are designed to be vibration resistant. This makes 4157 bulbs better suited for off-road applications, such as Jeep and ATV lighting.

Brightness

The 3157 bulb produces a brightness of 1,000 lumens, while the 4157 bulb produces a brightness of 1,200 lumens. This means that the 4157 bulb produces 20% more light than the 3157 bulbs.

Interchangeability

The 3157 and 4157 bulbs are interchangeable, meaning that they can be used in the same fixtures. However, it is important to note that the brightness and power rating of each bulb is different, so the brightness and power rating of the fixture must be taken into consideration when replacing a bulb.

Conclusion

3157 and 4157 bulbs are both great options for different applications, but they have some key differences. 3157 bulbs have a shorter lifespan and produce a brighter light, while 4157 bulbs have a longer lifespan and produce more light.

Both bulbs are interchangeable, but the brightness and power rating of the bulb must be taken into consideration when replacing a bulb.
