Understanding the Differences Between 3157 and 3156 LED Bulbs

If you want to boost your car or truck’s lighting look, consider equipping your ride with the unbeatable brightness of LED bulbs. LED (Light-Emitting Diode) bulbs are a popular choice for drivers for many reasons.
When it comes to automotive lighting, LED bulbs, specifically the 3157 and 3156 models, offer an unmistakable light output, energy efficiency, and longevity with which stock incandescent bulbs cannot compete.
 

What are 3157 LED Bulbs?

Many people opt for 3157 LED bulbs to upgrade or update their car or truck’s lighting.

 

Specifically, these bulbs are used as direct replacements for tail lights, turn signals, and parking or DRL (Daytime Running Lights) in compatible vehicles.

There are several key features and benefits of using 3157 LED bulbs. For example, Underground Lighting’s 3157 LED switchback bulbs are a quick, easy-to-install solution that comes in bright white/amber colors.

The dual-colored 3157 switchbacks LED offers 360 degrees of maximum output for a brilliant shine, minus bothersome hyperflash or error codes to disrupt your ride.

The ultra-bright 3157 amber LED bulb boasts a CANBUS switchback with a built-in resistor on the turn signal filament, which prevents overheating/melting or falling apart of the housing or LED that occurs when there are resistors on both the white and amber filaments–a common issue found with other brands.

Finally, 3157 LED bulbs’ amber color is equipped with 54 SMD LEDs–18 LEDs are for pure white, and 36 LEDs are for deep amber color.


What are 3156 LED Bulbs?

If your exterior car or truck lights need a sleek refresh, 3156 LED bulbs are another efficient, effective option.

These single-contact bulbs are often used as replacements for turn signals, brake lights, tail lights, and Daytime Running Lights upgrades.


What makes the 3156 bulbs a savvy choice?

UGL’s innovative design allows drivers to enjoy 360 degrees of light output, “plug and play” installation, and a built-in silent fan to cool and prevent overheating.

Additionally, the cooling fan increases the bulbs’ longevity–which saves you time and money while simultaneously upping your vehicle’s style factor.


 

Key Differences Between 3157 and 3156 LED Bulbs

 How do these two LED bulb types differ?
 
  • Difference in Filaments: The main difference between the 3157 and 3156 model is the number of filaments that each bulb contains, which is determined by differences in their wiring.
  •  
  • Number of Filaments: The 3156 bulb has one filament, and the 3157 contains two.
  •  
  • Base Compatibility: Keep in mind that although the base of the two bulbs is the same, they are not always interchangeable.
  •  
  • Dual Filament Functionality: The 3157 is a dual filament bulb that projects both high and low brightness. Drivers who use the 3157 as a front turn signal light, it can do double duty as a turn signal and Daytime Running Light bulb.
  •  
  • Single Functionality: The 3156 model is a single-function LED bulb with one brightness level that does not switch between high and low brightness.
  •  
 

Applications and Use Cases

 

3157 LED bulbs are most used in cars or trucks that need to alternate brightness levels.

They can also be used on some trucks as side marker lights, making them an optimal choice for this type of vehicle.

On the other hand, 3156 LED bulbs are often used in automobiles effectively as a great choice for front or rear turn signal, reverse light, or Daytime Running Light.

When comparing 3157 and 3156 LED bulbs, key differences include the number of filaments, compatibility range, and light output capabilities.
