If you’re looking to improve visibility on your vehicle at night, you’ve probably found many options for LED upgrades but almost all LED bulbs on the market are too large to install, they don’t work with the electrical system, and they have no focus or hotspot in the beam pattern. Even if they come close on those aspects, they still aren’t anything close to the quality you would find with factory-installed lighting. With the Diode Dynamics H11 SL1 LED Fog Light Bulbs, Diode Dynamics set out to engineer a true OEM-grade solution.

If you’re looking to improve visibility on your vehicle at night, you’ve probably found many options for LED upgrades but almost all LED bulbs on the market are too large to install, they don’t work with the OEM electrical system, and they have no focus or hotspot in the beam pattern. Even if they come close on those aspects, they still aren’t anything close to the quality you would find with factory-installed lighting. Like most aftermarket products, most LED bulbs are not engineered and tested for long-term reliability. With the Diode Dynamics H11 SL1 LED Fog Light Bulbs, Diode Dynamics set out to engineer a true OEM-grade solution. With its compact size, optically correct output, flow-simulated cooling, and boost-mode electrical circuit, the Diode Dynamics H11 SL1 LED Fog Light Bulb’s patented design is a properly-engineered solution that finally provides a true upgrade in performance, with high reliability: and it’s tested and validated to meet those standards, exactly like OEM lighting.

Diode Dynamics H11 SL1 LED Fog Light Bulbs includes two bulbs, to replace the factory fog light bulbs in your Sprinter. The Diode Dynamics H11 SL1 LED Fog Light Bulbs are compact in size, in a patented design that isn’t much bigger than the original halogen bulb. The drivers are compact too! If you have a sealed lamp, they are designed to fit inside. The drivers and bulbs are tested to last over time, even when sealed inside.

Street Legal Output. Don’t be fooled by high lumen numbers. Your Sprinter’s lamps are designed as a system, to focus light. If the light source in that system 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, you’ll just have more glare. To correct this, the Diode Dynamics H11 SL1 LED Fog Light Bulbs bulb was engineered with advanced optical design software, which simulates each ray of light in a process known as “ray tracing.” Using this tool, our engineers perfectly matched the filament location, allowing the Diode Dynamics H11 SL1 LED Fog Light Bulbs to focus light just like your original bulb, preserving the focus and hotspot, with no added glare. This is a safe, functional output, in compliance with photometric standards.

Tested to Perform. We test the Diode Dynamics H11 SL1 LED Fog Light Bulbs in factory lamps, and measure the entire beam pattern using specialized equipment. It’s an elaborate affair: a lamp is mounted to a computer-controlled rotating head called a goniometer. Light shines down a tunnel, where a sensor collects data as the light is rotated. The entire beam pattern is mapped, and we compare the total output to the original halogen. With proper optical engineering, testing, and validation in the application, we can assure correct optical performance.

SL1 Heat Comparison

Staying Cool. You may have seen bulbs that use large straps for cooling, or big fans that just make noise. These bulbs still run hot, pushing the LEDs past their limits, 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, it comes together as a whole system that was extensively tested, with dozens of iterations to achieve the best cooling performance possible. It includes a direct-solder copper core board, thermal phase-change interface material, and thermally-modeled zinc casting get heat to the base, where base fins are 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 patented design, the Diode Dynamics H11 SL1 LED Fog Light Bulbs 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 an exclusive reinforced shroud to keep the heat off any other components or wiring. Only slightly larger than a standard halogen bulb, it fits behind dust caps and in tight spaces. The driver and bulb are tested to function when sealed inside – no worries about heat buildup! The base sizes on the bulb are also are keyed for exact applications, not one-size-fits-all, and the compact driver easily tucks away.

Driven. Rather than a simple buck regulator found on other bulbs, the SL1 uses a unique boost-mode circuit, which prevents thermal imbalance in the LEDs over time – again, just like you would find in OEM LEDs. It also has transient protection for long life in automotive circuits. Diode Dynamics engineers also analyzed dozens of OEM electrical systems, and added current-monitoring circuitry to mimic the electrical characteristic of halogen bulbs, drastically reducing the need for CAN-BUS adapters (though they’re still needed on some applications).

Reliability. Every part of the Diode Dynamics H11 SL1 LED Fog Light Bulbs was designed for reliability, from the custom wiring with strain reliefs and solderless terminals, to the exclusive zinc castings, to the reinforced high-temperature PP-GF plastics (the same used in halogen bulb bases). Each component was designed and tested, with dozens of variations of each component reviewed until we achieved the maximum performance possible. Finally, the SL1 was put through its paces in our environmental testing chambers – where the bulb successfully performed through dozens of thermal cycles, from -40 through 85 degrees Celsius (-40 to 185F). Whether you’re in the Sahara or northern Canada, 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 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. No matter what you’re driving, we pride ourselves in offering only the best possible LED solutions.
