Default LED Headlight Bulbs 2015-2019 WRX-Made in USA! | Diode Dynamics





Diode Dynamics is pleased to offer the USA-made SL1 LED Headlight Bulbs for the 2015-2019 Subaru WRX!




SL1 LED Headlight. If you're looking to improve your visibility at night, you've probably seen many options available for LED upgrades. There's plenty of LED bulbs on the market, but they all have their shortcomings. They're too big to install, have no hotspot in the beam pattern, or they simply stop working after just a few months. With its compact size, optically correct output, thermally-modeled cooling, and boost-mode electrical circuit, the SL1 LED finally provides a true upgrade in performance.


Street Legal Output. Don't be fooled by high lumen numbers or "projector specific" bulbs. Your car's headlights are designed to focus light. If the light source is out of focus, it doesn't matter how bright it is - you won't have a focused hotspot of light to shine down the road - just more glare. To correct this, the SL1 LED headlight bulb was engineered with advanced optical design software, to perfectly match filament location. This allows the SL1 LED to focus light just like an original bulb, preserving the focus and hotspot, with no added glare. It produces a functional beam pattern on the road, in compliance with photometric standards, for a safe, functional output, which we call Street Legal.


Tested to Perform. We test the SL1 bulb in factory headlamps, and measure the entire beam pattern using specialized equipment. It's an elaborate affair: a headlight is mounted to a computer-controlled rotating head called a goniometer. Light shines down a tunnel, where a sensor collects data as the headlight is rotated. The entire beam pattern is mapped, and we compare the total output to the original halogen, confirming that the SL1 bulb shines more light in the hotspot, without adding extra glare on the road. The test results speak for themselves: in most lamps, like the 2015 F-150 Halogen lamp below, there is 30-70% more light in the critical hotspot, with no added glare or spread of light. With optical engineering, testing, and validation in the application, we can assure correct optical performance.





Staying Cool. You may have seen bulbs that use large straps for cooling, or fans that just make noise. These bulbs run hot, resulting in degradation of output after a few months. When it comes to cooling, proper engineering is required to efficiently remove heat from the bulb. In the SL1, a copper core board, thermal phase-change material, and thermally-modeled zinc casting get heat to the base, where base fins release it, designed for aerodynamic performance in conjunction with the flow rate and pressure of the Sunon bearingless microfan. The result is a highly-effective and reliable cooling system, keeping the bulb running at maximum potential.


Fitment. With its patent-pending design, the SL1 LED fits where other bulbs won't, without cutting or modification. There's no hanging metal straps, just a compact bulb that plugs right in, with a nylon-reinforced shroud. Only slightly larger than a standard halogen bulb, it fits behind dust caps and in tight spaces. The base sizes are keyed for exact applications, not one-size-fits-all, and the compact driver easily tucks away.


Reliability. Every part of the SL1 LED was designed for reliability, from the high-temperature teflon wire, to the zinc castings, to the reinforced plastics. The compact driver uses a unique boost-mode circuit, which prevents thermal imbalance in the LEDs, and has transient protection for long life in automotive circuits. Finally, the SL1 bulb was put through its paces in our environmental testing chambers - where the bulb successfully performed through dozens of thermal cycles, from -40 through 150 degrees Celsius. The SL1 will keep performing for years, and is backed by a three year warranty.


Experience. After over a decade in business, Diode Dynamics is the most trusted name in automotive LED lighting. Unlike every other LED distributor, we manufacture and engineer products ourselves in the United States, for high quality and fast time-to-market of the newest and brightest LED technologies. We pride ourselves in offering only quality LED products, that will exceed your expectations.

Are you looking to make the switch from halogen to LED headlight bulbs? Before you do, check out this video to ensure you choose the best one.

Good optical focus means more light further down the road where you need without any glare. We put together this video to highlight what to look for when choosing an LED headlight bulb for your vehicle. Check it out! And don't forget to shoot us a PM for free USPS shipping on any U.S order!

Think having LED headlight bulbs shine light 360-degrees is a good idea? Think again! Check out this video to see why!*

How hot an LED headlight bulb gets has a BIG impact on how bright it will be over time and how long it will last. Check out this video to see if your headlights are getting too hot!

Do you guys have drl's for 15 sti?
I have had terrible luck and reliability from OLM.

Need some fogs as well.

Great question!

We've had a lot of STi owners run our 9005-size SL1 LED Headlight Bulbs for the DRL. The only thing to note is that because the SL1 requires so little power, it will function at full brightness any time it's on.

For fogs, I'd recommend checking out our SLF Fog Light LED Bulbs. It's a direct plug-and-play upgrade, and the 3000K pure yellow option looks awesome if you ask me.
