Overview

Modern Foglights. Replacement LED bulbs are a great way to improve the look of the fog lights on your Subaru STi. Whether you’re matching the headlights, replacing worn-out standard bulbs, or just adding some style, this is one of the easiest and most effective upgrades you can make for the overall lighting setup on your STi.

Brightness. All Diode Dynamics LED lighting is rated with accurate, measured lumen figures, not calculations or guesses. We test the true output in-house, and provide you the real numbers to compare. Most of the H11 LED fog light options we offer are for cosmetic upgrade purposes only, to provide a modern LED appearance on your STi. If you’re looking for the maximum output, the SL1 is the best option for you. We also recommend the SLF LED, which is a bulb specifically designed for fog lamp applications, and is available in cool white or a pure yellow color.

True Colors. Our LED fog light bulbs are available in two colors: cool white and yellow.

The cool white LED options provide a pure, crisp white output without any hint of blue. They are a perfect match for most factory LEDs and HID components, to provide a uniform, clean appearance on the road.

The yellow option is a pure, brilliant yellow tone. Unlike other manufacturers who use lenses with white LEDs to achieve a yellow color, the yellow SLF option uses dual high-power true yellow LEDs instead–no lens needed! This means you end up with a pure yellow color, instead of the greenish yellow color you may have seen from other generic yellow bulb options.

Tested. Most of us have seen lighting setups with random shades of white that don’t quite match. At Diode Dynamics, we operate an integrating sphere, which is a piece of lab equipment used to analyze the exact color spectrum of the LED bulbs we produce. By testing each batch of products, we can ensure that all bulbs will match in color, to avoid various tints of white. These bulbs will match any other upgrades you may have from Diode Dynamics, for factory-style uniformity and a clean appearance.

Reliability. Diode Dynamics LEDs are built with constant-current inductive circuitry, along with transient suppression. They are tested by our engineering team with a device that replicates years of voltage spikes, like the ones generated each time the alternator starts and stops on your STi. This is what kills most LED bulbs over time, but just like factory components, Diode Dynamics LED bulbs are designed with built-in circuit protection. While more expensive than simple bulbs, this allows Diode Dynamics LEDs to last for years, with no flickering or failure.

Experience. After over a decade in business, Diode Dynamics is one of the most trusted names in automotive LED lighting. We directly assemble and engineer an increasing number of products in the United States, allowing for higher quality and performance, with the newest and brightest LED technology. Whether it’s a Subaru or anything else, we pride ourselves in offering only the best possible LED solutions. Please contact us if you’d like to discuss your lighting project!
