AFTERMARKET OR OEM: If you're looking to improve visibility on your vehicle at night, you've probably found many options for LED upgrades. Most bulbs on the market are too big to install, don't work with the electrical system, and 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 SL1 LED, 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, our SL1 LED 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, just like OEM lighting.

COMPACT SIZE: Your order includes two bulbs, to replace the factory bulbs in your vehicle. The 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 vehicle'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 SL1 LED 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 SL1 LED 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 SL1 bulb 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.

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 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 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 SL1 LED 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.

OPTIONAL ACCESSORIES: Even though these bulbs are designed to be plug-and-play, some makes and models require additional accessories to complete the installation. Many vehicles do not need anything additional while others may need one or all of these accessories. You can try the LED bulbs without any of these accessories and add them later if needed.

ANTI-FLICKERS: If your vehicle has PWM (Pulse Width Modulation) or CanBus, you may experience flickering, shutting off, or errors on the dashboard once you install the LED bulbs. This is an easy fix, simply add our anti-flicker cancellers to prevent any issues caused by PWM or CanBus. These plug directly between the LED bulbs and your factory harness. If your headlamps have a dust cap, you will drop these inside of the housing before you install the bulbs.

BULB ADAPTERS: When you remove your stock halogen bulbs, if there is a metal or plastic adapter that locks the bulbs into place, you will most likely not be able to reuse it for the LED bulbs. However, we have a wide selection of aftermarket LED Bulb Adapters that will replace your stock model.

RUBBER DUST CAPS: If your factory housing dust cap will no longer fit your headlamp due to the rear section of the LED bulbs is too large, you will need to replace it with aftermarket LED Housing Dust Caps. You can measure the opening of your housing to select the exact size you need or select the universal model which can be trimmed down to the size you need.
