A Buyer's Guide for Choosing the Best LED Turn Signal Bulbs

The primary concern of all motorists on the road is safety. Vehicle manufacturers offer a variety of front and exterior lighting features for their vehicles that are designed to enhance your overall safety while driving. Most people focus more on the visibility that front lighting provides for driving at night but sometimes overlook the indicator role of the turn signal function.

Turn signal lights enable you to clearly indicate which direction you plan to go, as well as safely change lanes. When your turn signal bulb goes out or does not respond in a timely manner, you will not be able to alert drivers in front or behind your intended actions. So the malfunctioning turn signal bulbs render your vehicle a safety hazard on the road.

How Do I Know If I Need To Replace A New Turn Signal Light Bulb?

• Other Drivers Don't Respond To Your Turn Signal Lights

• The Turn Signal Light Doesn't Illuminate

• OEM Turn Signal Light Is Dim

• Your Hazard Lights Don't Work

• Dashboard Warning Notification

• Improved Vehicle Turn Signal Lighting

What are the advantages of LED Turn Signal bulbs?

LED turn signals have many benefits and are a great way to improve your road driving safety. The most noticeable difference is the brightness between the LED bulbs and the original halogen bulbs on your vehicle. Everyone else on the road will clearly see you when you use your turn signal, and that’s precisely what you want.

Another advantage is that the LED switches on faster than the incandescent bulb. It switches on faster even when it is cold, allowing other drivers to know more promptly what you want to do next.

1. Confirm the bulb of the turn signal lights

Here are three ways to help you confirm the bulb model.

• Use the AUXITO Bulb Finder to find the front turn signal/rear turn signal bulb model recommended for your vehicle

• Look up the model owner's manual to confirm the turn signal bulb size

• Remove the original halogen bulb and check the model number marked on the bulb

2. Choose turn signal bulb color

Generally, the front turn signal bulbs are amber in color, while the rear turn signals are red or amber.

You also need to pay attention to the color of your vehicle's turn signal shades. If the shade color is amber, then you can choose amber or white LED bulbs for replacement.

If you want to choose a different color turn signal, the confirmation of your local state laws is required.

3. Types of turn signals

• SWITCHBACK FUNCTION LED TURN SIGNAL LIGHT BULB

*Note: These will only work for dual function lights that have both the parking/city light and turn signal function in one bulb

Many vehicles share the parking or running lights with the turn signals and are usually yellow or amber from the factory for both modes. When turn on the low beams, if you are tired of amber as a constant DRL, then Switchback LED dual filament lights are your best choice.

The LED switchback bulbs offer the Xenon White color during parking light mode while blinking as Amber during the turn signal mode, so the indicators stay within the legal color allowed by law. But the parking light keeps your front lighting stylish and consistent with a cool white look when the LED headlights are on!

In addition, this LED bulb provides better vehicle visibility for other drivers by utilizing the "Amber-Off-Amber-Off" color change when using the turn signal function.

• ONLY AMBER LED TURN SIGNAL LIGHT BULB （Front or Rear)

1 ）AUXITO 4KP8 Series Super Canbus error-free

Abnormal flashing and error codes occur when replacing the turn signal bulbs on some vehicles, such as Audi, Mercedes-Benz, BMW, Porsche, etc. And you can try to add a resistor decoder or relay to solve such problems. But these extra parts are very tricky to install and still don't work in some vehicles with sensitive CANbus systems.

The CANbus error-free LED turn signal bulb is designed to mimic the power draw of the original halogen or HID turn signal bulbs to ensure a hassle-free installation. This newly upgraded turn signal bulb is plug and play, as easy as installing an OEM halogen bulb.

You don't have to worry about cutting or splicing wires to install resistors or relays, even though it's a sensitive model, and you don't have to worry about problems after installation!

*Note: These LED bulbs are used as turn signal lights ONLY. (They are single-function, and could not be used as day running lights or parking lights)

2 ）AUXITO 2G42 Series, 54H Series, 120H Series, and 5KG26 Series

If you purchase an LED turn signal bulb that does not emit 360° light due to the position of the LED chip design, the LED bulb may have a blind or black spot when placed in the reflector, which can make the beam pattern of the turn signal light not as aesthetically pleasing.

Based on the problems mentioned above, AUXITO offers you turn signal bulbs with sequencing LED chips precisely around the bulbs. They provide 360° high luminous efficiency and full amber light with no blind spots. The brighter amber turn signal lights are much easier noticed and much safer for driving. And these LED bulbs are plug-and-play, no modifications are required!

Solve the problem of LED turn signal decoding

When you want to upgrade your vehicle’s turn signals from yellowed, dim Halogen bulbs to newer, brighter, better LED bulbs, you may notice that they are blinking much faster than your previous bulbs or pop up in the dash with errors.

Since LED bulbs draw far less power than the original halogen or HID bulbs, the computer in the vehicle may think that the bulb is out so it'll throw an "error message" or "bulb out" warning the driver that the light is out.

If there is a flashing turn signal bulb, how do I fix it?

When you upgrade to an LED bulb with a decoding error, you can try connecting a load resistor across the wires feeding the turn signal light bulb.

Through the use of a load resistor kit (pictured right), the flashing speed of LED bulb can be reduced to the regular rate. These resistors will be installed in parallel (tied to positive and negative) for each LED bulb.
