For Subaru Impreza WRX STi Interior LED Lights - Dome & Map Light Bulbs Package Kit for 2002 - 2019 - White

What is an LED light?

LED stands for Light Emitting Diode. It's a semiconductor device that emits light when an electric current passes through it. LED lights are energy-efficient and long-lasting.

What is color temperature?

The color temperature of LED lights refers to the perceived warmth or coolness of the light emitted, measured in Kelvin (K). Common color temperatures for LED lights range from warm white (around 2700K-3000K) to cool white (around 4000K-5000K) to daylight white (around 5000K-6500K).

What are CK/SRCK and standard configurations, and why should I check my sockets?

CK/SRCK and standard configurations are two types of dual-filament sockets (e.g., 3157 & 7443) used in turn signal applications. Incorrectly installed LED bulbs can cause circuit shorts. Verify your vehicle's socket type with your local dealer or using a test lamp.

What is a dual-filament bulb?

A dual-filament bulb provides two levels of light intensity: low and high. For example, a tail light emits low-intensity light, while a brake light emits high-intensity light.

Why does my LED bulb flicker or dim when installed?

Some vehicles have systems that monitor lighting. Low power draw from LED bulbs can trigger errors. Install load resistors or decoders to trick the system into recognizing a functioning bulb.

Why is my turn signal flashing faster than normal?

LED bulbs' efficiency can lead to hyper-flashing. Install load resistors to simulate the power draw of halogen bulbs or upgrade the flasher relay module for LED compatibility.

What is an error-free LED bulb?

An error-free LED bulb is CAN bus-ready, preventing malfunctions in vehicles with advanced computer systems.

Which bulb size should I use?

Refer to your vehicle's owner's manual or the original bulb for the correct bulb size. Comparing the factory bulb to our product is a reliable method.

What are CAN Bus LED bulbs?

CAN Bus LED bulbs are designed for vehicles with Controller Area Network Bus systems, ensuring proper communication with the vehicle's computer.

Will CAN Bus LED bulbs prevent "bulb-out" indications?

CAN Bus LED bulbs should prevent "bulb-out" indications for tail, brake, and running lights in most cases.

Will CAN Bus LED bulbs prevent hyper-flashing?

CAN Bus bulbs won't prevent hyper-flashing. You may need load resistors or an electronic flashing relay for this issue.
