How do you know which turn signal bulb is out?

You may notice that either your left, right, or both turn signals are suddenly blinking very rapidly. This is a sign that your turn signal bulb (or both bulbs) is failing and need to be replaced soon.

Are all turn signal bulbs the same?

No, turn signal bulbs are not all the same. Each vehicle uses different part numbers, which will vary by manufactures. LED turn signal bulbs are the most popular choice when it comes to replacing the factory-standard incandescent bulbs for several reasons. LED bulbs project a brighter, longer-lasting, and more energy-efficient light than incandescent bulbs, which tend to become dull and dim.

Do turn signal LED bulbs need a resistor?

Yes, one LED resistor is required for each turn signal bulb. Are you in need of a great resistor? You’re in luck! Underground Lighting can assist you in choosing the best product for your car or truck.

Is it illegal to have blinking brake lights?

It is possible to receive a ticket for a rapid, continuously flashing red brake light. This is also a sign of a failing bulb. If you’re experiencing this issue on either one or both sides of your vehicle, it is in your best interest to replace the bulb(s) as soon as possible. Not only do you want to avoid receiving a ticket, but it is best to avoid any confusion on the road as well for safety’s sake.

Why are my brake lights flickering?

If you’ve noticed (or been told by another driver) that your vehicle’s brake lights are flickering, this is a sign that the bulb(s) may be going out, or that there is faulty wiring in the circuit. Easy, “plug and play” installation makes this cost-effective, long-lasting update to your car or truck a no brainer.

Why is my blinker going twice as fast?

Have you noticed your left, right, or even both blinker lights flashing twice as fast as normal? If so, 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, it is 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 much does it cost to replace a blinker bulb?

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

LED Front Turn Signal Switchback Bulbs W/ Built in Resistor

Best Performance in Industry.

Our Ultra Bright 24W 1200LM 7443 LED W/ Built-in Resistors DRL and/or Turn Signal Light Bulbs, No hyper flash (2 Pieces) cover 360 degrees to provide maximum output. Unlike other brands, with resistors on both the filament, we created a CANBUS LED that only has a built-in resistor only on the turn signal filament. Having a resistor on both the filament will lead to melting the housing or the LED falling apart in the housing. We even took it one step future to insure the longevity of the bulbs by adding a cooling fan. The fan only turns on when the turn signal is on, to reduce heat when resistor is on. Our Design protects the LED from being exposed to constant heat eliminating this issue. This assures no hyper-flashing or error codes. Our LED is designed to replace the factory incandescent bulb without the need to add extra resistors or parts.

Best-In-Class Brightness.

Each LED is equipped with 54 SMD LED chips giving 360 degrees of light to provide the max output Each bulbs is 1200Lm, your turn signals will shine a lot brighter than the stock incandescent bulb.

You’ll be hard-pressed to find a brighter, more efficient LED bulb on the market! Designed here in the USA, these bulbs feature an impressive 54 color LED chip design.

FAQs

Frequently Asked Questions on LEDs

Which Color Is Best for Headlight Bulbs?

The best color for your headlight bulbs is white. You want to find a bulb around the range of 6000k in color temperature. The human eye reads this color and brightness better due to its similarity to natural sunlight.

That said, the best color for your headlights can be subjective. LEDs are also available in yellow, blue, and purple. Each color will work just fine on the roads and give your car a more distinctive look than the traditional white color.

Will LED Headlights Damage My Car?

No. LED headlights will not damage your car if properly installed. In addition, you want to purchase the correct LED light that will fit your car. For example, if your vehicle has a CANbus system, you want to buy the right product and install it correctly to avoid any potential issues.

If your car was not originally designed for LED headlights, you can purchase an LED headlight conversion kit. They are safe and will not damage your vehicle as long as you buy top-quality products.

Why Are LED Lights Better?

An LED light bulb saves more energy, produces less heat, and has more light. In addition, it uses 85% less electricity than standard lighting. It is also a lower-cost product but has bright light with a longer life span.

LED light is different from incandescent light. Blue LED combined with yellow phosphor creates white light. The high efficiency of LED light makes it a popular choice.

What Is the Purpose of LED Lights?

LED lights are used as a light source in our homes, devices, and vehicles. LED (light-emitting diode) lights use gallium compounds such as gallium arsenide and aluminum gallium. LED emits light by combining a P-type semiconductor with an N-type semiconductor. Once a voltage is applied, they release energy into light.

What Is the Lifespan of LEDs?

LEDs have a long life span. When an LED is operating at 70% capacity, it has reached the end of its life span.

Incandescent bulbs have around 750 to 2,000 hours of light. In comparison, LED bulbs can have 50,000 to 100,000 hours of light, making them better investments.

Can I Replace Incandescent Bulbs with LED in My Car?

Yes! You can change your initial bulbs to LED in your vehicle. In addition, there are different places where you might want to swap out for LED lights. For example, you can change your headlights, rear license plate lights, interior door entry lights, rear brake lights, and more.

First, however, you need to inspect what type of bulb you need. There are different bulbs with various designs, so you must buy the right one to fit.

Second, different areas of your car may require special tools or specific parts to work properly. Once you have found the products you need, you’re ready to go LED.
