Modern LED illumination
Direct replacement for Subaru STi sidemarker light bulbs
Plug and play, no modification with factory 194 bulb size
Available in multiple brightness levels
Modern Upgrade. These replacement LED bulbs are a great way to improve the function and longevity of the sidemarkers on your Subaru STi. They'll provide modern illumination with long lifespan compared to the original incandescent bulbs. The installation is straightforward, with just a bulb swap - making it a simple upgrade for the STi's lighting setup.
Choose Your Color. You'll see that there are multiple color options for these bulbs. Please select what you need for your setup! If you have amber lenses in the front, select amber bulbs in order to maximize output. If you have clear front reflectors, like found in many aftermarket headlamps, you can use white or amber bulbs. For the rear, you'll always want to select red bulbs.
Front and Rear. This listing includes one pair of bulbs. If you need both front and rear bulbs, please add one of each to your cart in each respective color. You'll always need red in the rear, and amber or white bulbs are for the front of the vehicle.
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.
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 LEDs 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!
