Engineered for Performance. Made in USA.
APPLICATION NOTICE: LED bulbs are legal in the USA for Fog Light use only. Not compliant with DOT / FMVSS108 and not street legal in the USA for Headlights. Legal for off-road use in ATV, snomobile, and off-road racing use. International legality varies by country. Note: This usage regulation is not unique to Diode Dynamics bulbs. All LED bulbs from all brands, regardless of marketing claims, are prohibited from street use in halogen headlights in the USA.
True Upgrade. Other LEDs on the market are too big, have no hotspot in the beam pattern, or they simply stop working after just a few months. The SL1 LED bulbs finally provides a true upgrade in performance, with its compact size, optically correct output, and high reliability. The Lumileds chips shine in a true white 5700K color temperature, without any hint of blue, for an OEM-style appearance.
Focused Output. Don't be fooled by high lumen numbers. If the light source is out of focus, it doesn't matter how bright it is. You won't have focused light, you'll just have more glare. To correct this, SL1 LED bulbs were engineered with advanced optical design software, to perfectly match filament location of the original bulb. Learn more here.
The SL1 LED is designed to shine light just like the original bulb, which improves the capability to preserve the focus of the lamp, with no added glare.
Tested and Verified. To make sure everything works as intended, we use photometric test equipment to measure the entire beam pattern with the SL1 installed. A CNC rotating head called a goniometer holds a lamp. First, photometric test points are measured, as defined by SAE. Next, the entire beam pattern is mapped. This provides a full picture of the resulting output, and allows us to compare performance to the original bulb.
Fitment. With its patented design, the SL1 LED bulb fits where other bulbs won't. It will fit under dust caps, and in tight spaces with no modification. There's no hanging metal straps. It's simply a compact bulb that plugs right in.
Reliability. The SL1 LED is a durable, reliable bulb, and is backed by a three year warranty. From the high-temperature teflon wire, to the zinc castings, every part of the the SL1 was designed for reliability. The 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, through dozens of thermal cycles, from -40 to 150 degrees Celsius. We also test for vibration and electrical transient voltage to ensure long life. Learn more here.
If you’re looking to replace your factory bulbs, it’s time to upgrade to the SL1. Unlike other generic bulbs on the market, our SL1 LED bulbs have been designed to put more light where you need it—the road, while being compact enough to fit in vehicles where bulkier LED light bulbs won’t. Best of all, installing the SL1 is easy and only takes minutes. Simply remove your halogen bulb, and the SL1 fits directly in its place—no modification needed. So if you’re looking to replace your bulbs, upgrade to the next generation —SL1 LEDs.
