LED Headlight Bulbs for 2011-2019 Jeep Grand Cherokee! Made in USA! | Diode Dynamics

Diode Dynamics is pleased to offer the USA-made SL1 LED Headlight Bulbs for the 2011-2019 Jeep Grand Cherokee!

If you're looking to improve your 2011-2019 Jeep Grand Cherokee’s visibility at night, you've probably seen plenty of aftermarket LED headlight bulb options. There are plenty of “high performance” LED lights 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, Diode Dynamics SL1 LED Headlight Bulbs are truly the best LED headlight bulbs on the market.

SL1 Low Beam LED Headlight Bulbs for 2011-2019 Jeep Grand Cherokee

Street Legal Output. Don't be fooled by high lumen numbers or "projector specific" bulbs. Your 2011-2019 Jeep Grand Cherokee’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. Some generic options have such a poor optical design, they might leave you wondering “how are LED headlights legal?!”

To correct this, Diode Dynamics' SL1 LED Headlight Bulb was engineered with advanced optical design software, to perfectly match the halogen filament location. This allows the SL1 to focus light just like the original halogen headlights, preserving the focus and hotspot, with no added glare. It produces a functional beam pattern with zero glare, which we call Street Legal.

Tested to Perform. We test the SL1 in factory car headlights and measure the entire beam pattern using specialized equipment. The entire beam pattern is mapped, and we compare the total output to the original equipment, confirming that the SL1 headlight bulb shines more light in the hotspot, without adding extra glare on the road. The test results speak for themselves: in most lamps, there is 30-70% more light output in the critical hotspot, with zero glare. Thanks to optical engineering, testing, and validation in the application, the SL1 is the #1 LED headlight bulb for reflector and projector headlights.

Staying Cool. You might’ve seen LED headlight kits that use large straps for cooling, or fans that just make noise. These light 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 micro fan. The result is a highly effective and reliable cooling system, keeping the SL1’s LED chips running at maximum potential.

Fitment. With its patented design, installing the SL1 LED headlight bulb is simple and straightforward, requiring NO cutting or modification. There's no hanging metal straps, just a compact bulb that plugs right into your 2011-2019 Jeep Grand Cherokee, 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 specifically to fit your vehicle, not one-size-fits-all! And the compact driver easily tucks away.

Reliability. Every part of the Diode Dynamics' SL1 LED Headlight Bulb is engineered with more expensive OEM-grade features to assure quality, such as the Sunon MagLev fan and PCB wire connectors" In short, these are designed, tested, and built to a much higher standard than your average imported led headlight conversion kit. The Diode Dynamics' SL1 LED Headlight Bulb will keep performing in your 2011-2019 Jeep Grand Cherokee for years, and is backed by a three-year warranty.
