How to Choose the Best Automotive Turn Signal Bulbs
Bulb Type and Fitment
Understanding your vehicle's specific bulb requirements is paramount. Most turn signals use incandescent bulbs, but LED replacements are increasingly popular. Check your owner's manual or consult an online parts catalog to identify the correct base type (e.g., 1157, PY21W) and wattage for your vehicle. Using the wrong type can lead to electrical issues or a non-functional signal.
Frequently Asked Questions
Are LED turn signal bulbs legal?
Generally, LED turn signal bulbs are legal if they meet federal and state regulations for brightness and color. However, some vehicles require specific load resistors to prevent hyper-flashing when switching to LEDs. Always check local regulations and ensure your chosen bulbs are compliant.
What is hyper-flashing?
Hyper-flashing is when turn signal lights flash at a much faster rate than normal. This often occurs when switching from incandescent bulbs to LEDs due to the lower power draw of LEDs. Resistors or specialized LED flasher relays are typically used to correct this.
How long do LED turn signal bulbs last compared to incandescent?
LED bulbs typically have a significantly longer lifespan than traditional incandescent bulbs. While incandescent bulbs can last thousands of hours, LEDs can last tens of thousands of hours under normal operating conditions, reducing the need for frequent replacements.
Can I mix incandescent and LED bulbs in my turn signals?
It is generally not recommended to mix incandescent and LED bulbs in the same lighting system, particularly for turn signals. This can lead to unpredictable electrical behavior, such as hyper-flashing or one bulb not working correctly. It's best to use matching bulb types for optimal performance and safety.
