LED Turn Signal Bulbs

Start by identifying your vehicle's specific bulb requirements to ensure compatibility and optimal performance.

Check your bulb number in three quick steps:

1. Locate your current turn signal bulb, carefully remove it from the housing, and check the part number on its base. Common bulb sizes are 1156, 1157, 7440, 7443, 3157, and 3156. Each type has specific base configurations and electrical requirements that must match your vehicle's specifications.
2. Enter your vehicle's year, make, and model into our fitment finder to verify the exact bulb you need. You can also check the maintenance section in your owner's manual.
3. Choose your LED turn signal bulb with confidence - our fit guarantee guarantees you'll receive the correct bulb that matches your vehicle's specifications perfectly.

How do you know which turn signal bulb is out?

When your turn signal starts blinking faster than normal (known as "hyper-flashing"), it usually indicates a burned-out bulb. 

To identify which one isn't working properly, switch on your hazard lights and walk around your vehicle - the non-functioning bulb will be obvious. You can also activate your turn signals while parked next to a reflective surface like a wall or window, making it easy to spot which side isn't working.

Are all turn signal bulbs the same?

No, they aren't all the same. Each vehicle uses different part numbers, which will vary by manufacturer. LED turn signal bulbs are the most popular choice when replacing factory-standard bulbs, as they project a brighter, longer-lasting, and more energy-efficient light.

Do turn signal LED bulbs need a resistor?

Most vehicles require one resistor per bulb when upgrading to LED bulbs. Why do LED turn signal bulbs need resistors? They draw significantly less power than traditional bulbs, which can cause incorrect flash rates.

However, some LED bulbs, like our 3157 LEDs with built-in resistors, eliminate the need for separate installation. The advantages of 3157 LED turn signal bulbs with built-in resistors are easier installation and guaranteed proper operation without additional components. 

Why is my blinker going twice as fast?

If you've noticed that your LED turn signal bulbs are flashing too fast, this is a signal from your vehicle that your blinker bulb(s) are going out and need to be replaced as soon as possible. Not only is the rapidly blinking light and noise annoying, but it is also a warning to you to take action as a responsible driver before you either receive a ticket or the bulb goes out completely, resulting in a possible roadside accident.

How do turn signal bulbs work?

When the driver activates the turn signal through the vehicle's controls, an electric current signals the bulb. This current flows through the filament (incandescent bulbs) or the semiconductor material (LED bulbs), generating light. A relay controls the flashing pattern, which causes the light to blink consistently. 

How much does it cost to replace a blinker bulb?

The cost can be an immediate concern when it’s time to replace a failing or completely dead blinker bulb (or both!). However, longer-lasting, more energy-efficient turn signal bulbs that project the perfect amount of light output without casting a blinding glare on other drivers are well worth the investment. We have LED turn signal bulbs starting at $39.99 that burn brighter and last longer than other retailers.

What's the difference between switchback LED bulbs and regular LED turn signal lights?

Based on their design, switchback LED bulbs and regular LED turn signal lights have different functions. Switchback bulbs operate in two colors - white when the turn signal is off, functioning as a daytime running light, and amber-yellow when it's activated. Regular LED turn signal bulbs operate in a single color, illuminating only when the turn signal is engaged. 

What are the best LED Lights for turn signals? 

When you're choosing the best LED turn signal bulbs, look for bulbs that offer proper heat management, consistent light output, and appropriate beam patterns. Important features include durable construction, efficient cooling systems, and compatibility with your vehicle's electrical system. Consider factors like brightness levels, color accuracy, and whether you need anti hyper-flash. 

How long do LED turn signal bulbs last?

LED turn signal bulbs typically operate for 30,000 to 50,000 hours under normal conditions. This extended lifespan means fewer replacements than traditional halogen bulbs, as LEDs are built to withstand vibration and varying weather conditions.

You can maintain your turn signal bulbs by keeping the housing clean and ensuring proper electrical connections. While they cost more initially, their durability and efficiency often make them a practical choice for many vehicles.

Should I choose LED or halogen lights for my car?

If you compare LED vs halogen bulbs, you’ll notice each type offers distinct characteristics for your vehicle lighting needs. Halogen bulbs provide traditional lighting performance at a lower initial cost, whereas LED bulbs deliver brighter illumination, operate more efficiently, and typically last significantly longer than halogens.

When making your choice, think about your regular driving conditions, budget requirements, and vehicle compatibility. Some vehicles may require additional components for LED installation, while others are designed for simple plug-and-play operation.
