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.

Description

3156 T20 LED Bulbs For Turn Signals and DRLs

Looking for 3156 LED bulbs for your car or truck? These T20 bulbs are a direct replacement for compatible 3156, 4156, and T20 bulbs. Each bulb uses 27 three-emitter 5050 SMD LEDs to provide bright, even light in all directions, rather than focusing in one direction. Use them for turn signals, backup and reverse lights, and daytime running lights.

The SRCK non-polar design makes installation easier because the bulb doesn't require polarity matching. This can simplify the replacement process when upgrading from factory halogen lighting to LED.

If using these T20 LED bulbs for turn signals, you may need a pair of load resistors to prevent hyperflash or malfunction.

For backup/reverse or DRL applications, follow the vehicle's bulb and socket requirements for the specific application.

Frequently Asked Questions (FAQ)

Do you offer free shipping?

Yes. Underground Lighting offers free shipping on orders over $99.90.

How much does this T 20 3156 LED bulb cost?

This T20 3156 LED bulb costs $39.99 per pair. The set includes two amber bulbs, each using 27 three-emitter 5050 SMD LEDs with 360° light coverage, and comes with a 1-year warranty.

Are 3156 LED and 4156 LED bulbs the same?

Yes. 3156 LED and 4156 LED bulbs use the same T25 wedge-base design and are generally interchangeable for compatible single-function applications, such as backup or reverse lights. Both are single-intensity bulbs, so they operate at one brightness level rather than switching between low and high brightness like a 3157.

What does a 3156 bulb fit?

A 3156 bulb fits single-contact T25 wedge sockets and is commonly used for reverse/backup lights, turn signals, parking lights, and other single-function vehicle lighting. It is also commonly cross-referenced with 3456 and 4156 where the vehicle calls for the same socket and function.

Can I replace a 3156 with a 3157 LED in my Car?

Yes, you can replace a 3156 bulb with a 3157 LED in a single-function socket, such as a reverse or backup light. Both bulbs use the same wedge-base size, so a 3157 LED will physically fit a 3156 socket and operate at its maximum brightness because it uses only one circuit.

The reverse is not true. A 3156 cannot replace a 3157 in a dual-function application because a 3156 has only one circuit, while a 3157 has separate circuits for low- and high-intensity functions.
