Each LED brake bulb is designed for quick, plug-and-play installation, making it easy to swap out your old incandescent bulbs. Not only do our LEDs shine brighter, but they also give your car a clean, modern look while improving visibility when braking.

LED Bulb Base Compatibility: What You Need to Know

Selecting the right LED bulb for your vehicle involves more than just brightness or color—it comes down to base compatibility. This includes the number of electrical contacts, the pin configuration, and whether the bulb supports single or dual functionality. These details ensure the bulb fits securely and works as intended.

A simple example is the 3156 vs. 3157 bulb. While they look similar, the 3156 supports a single function with one contact point. The 3157 has two, enabling it to switch between low and high brightness modes—ideal for lights that function as both tail and brake lights.

Base Types: Wedge and Bayonet

Most LED bulbs used in tail lights, brake lights, or turn signals have either a wedge or bayonet base. Wedge bases push into the socket, while bayonet bases twist to lock in place. Both types come in single- or dual-contact versions. Choosing the right one is simple if you use a side-by-side visual guide or a bulb compatibility tool.

Single and Dual-Function LEDs

Single-function LED bulbs are designed to operate at one brightness level and serve one purpose, such as signaling a turn or illuminating in reverse.

Dual-function bulbs, however, can handle two roles using the same bulb. These have two contact points and often switch between two brightness levels. This makes them ideal for setups where one bulb must act as both a running light and a brake light.

Why Consider Switching to LED Tail and Brake Lights?

Upgrading to LED tail and brake lights can offer several key advantages over traditional bulbs:

1. Built to Last

Unlike conventional bulbs, LEDs have no filaments. That means they're less likely to fail due to shock, vibration, or everyday wear and tear.

2. Instant Illumination

LEDs light up nearly instantly when activated. This faster response time can give drivers behind you crucial extra milliseconds to react—especially when braking.

3. Long Life Expectancy

LED car lights can last over 30,000 hours, often outliving halogen bulbs by 20 to 25 times. Fewer replacements mean less hassle and long-term savings.

4. All-Weather Performance

Operating efficiently in extreme conditions—from -22°F up to 185°F—LEDs are reliable whether it's freezing cold or scorching hot.

5. Better Visibility and Steady Brightness

Brighter and more uniform, LED lights make your vehicle easier to see, improving safety for everyone on the road. Unlike traditional bulbs that dim over time, LEDs maintain their brightness consistently throughout their lifespan.
