3156 LED Bulbs & 3157 LED Bulbs

3156 and 3157 LED bulbs have slightly different functions, even though they look similar. The 3156 LED bulb is a single-function bulb commonly used in tail lights, reverse lights, and brake lights. The 3157 LED bulb, however, is a dual-function bulb designed for applications that need both low-intensity and high-intensity operation, like tail lights that double as brake lights or turn signals. 

If you're looking to improve safety, customize your vehicle's lighting, or reduce maintenance costs, these LED light bulbs are a versatile and practical choice. Illuminate the road ahead with the brilliance of 3156 and 3157 LED bulbs and experience a brighter, safer, and more efficient journey on the road.

Finding the right LED replacement bulb is easy with our expert guidance:

1. Check Your Vehicle’s Manual: Look up the required bulb type for your specific make and model under “lighting specifications” or “bulb replacement.”
   
   
2. Examine Your Existing Bulb: Remove the bulb and check the base. If it has a dual-contact base, it’s likely a 3157 LED bulb, and if it has a single-contact base, it’s a 3156 LED bulb.
   
   
3. Use Our Vehicle Finder Tool: Enter your vehicle details on our website to ensure you get the correct fit.

Will a 3157 LED Bulb work with a 3156 socket?

Yes! The 3157 LED bulb is the dual filament option for the 3156 LED bulb, and you can easily use it in the same socket. The two will work together seamlessly to instantly upgrade and update your older, dimmer Halogen bulbs with the unmatched brightness of an LED Turn Signal. However, a 3156 bulb can’t work in a 3157 Socket.

Do I need a load resistor for 3157 LED bulbs?

You will need a load resistor for each LED bulb you install on a turn signal circuit. In some cases, installing 3157 LED turn signal bulbs may cause hyper-flashing, so adding a load resistor can resolve this issue by mimicking the resistance of traditional incandescent bulbs.

Can I use 3157 instead of 4057 bulbs?

Yes, the 3157 bulb is compatible with many different bulb sizes, including the 4057. You’ll be more than impressed with the unmatched light output that comes with installing newer, brighter LED bulbs - in addition to the added safety. A brighter light that won’t blind other drivers on the road keeps everyone safe and able to see clearly in even the darkest road conditions.

How do I install 3157 & 3156 LED Bulbs?

Installing 3157 and 3156 LED bulbs is a straightforward process. Start by turning off your vehicle and removing the old bulb from its socket. Then, carefully insert the new LED bulb into the socket, making sure it's securely in place. You need to test the bulb to confirm it works correctly before reassembling any components, and always handle the bulbs carefully to avoid damage. 

If you come across any issues like flickering or non-functioning bulbs, check for compatibility or use a load resistor to resolve electrical inconsistencies. For easy installation, check your vehicle’s manual and the bulb manufacturer’s guidelines.
