SL1 LED Headlight Bulbs for 2016-2018 Kia Optima




Diode Dynamics is pleased to offer the USA-made SL1 LED Headlight bulbs for Headlight for 2016-2018 Kia Optima


If you're looking to improve your 2016-2018 Kia Optima’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.

Diode Dynamics SL1 High Beam LED Headlight Bulbs for 2016-2018 Kia Optima


Street Legal Output. Don't be fooled by high lumen numbers or "projector specific" bulbs. Your 2016-2018 Kia Optima’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, the 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 2016-2018 Kia Optima, 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 2016-2018 Kia Optima for years, and is backed by a three-year warranty.

LED Focus: What you need to know!




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!

Measuring Headlight Output | Diode Dynamics

How are headlight output patterns measured at the factory level? How do you test to see if a headlight is meeting SAE and DOT beam pattern requirements? Here at Diode Dynamics, we've invested in a goniometer to accurately measure and map the entire beam pattern and ensure our products are adding light output without adding extra glare.

Check out the video to see how it works!

Our SL1 LED Headlight Bulbs were built to last. And we've done the testing to prove it. Check out a behind-the-scenes look into our lab where we conduct thermal, vibration, and electrical testing to ensure years of reliable performance without flickering or failure!

How do these compare to, say Hikari's offerings? Are these brighter/longer lasting? Or are they a similarly priced equivalent?
Great question!

We haven't yet done side-by-side testing with that particular brand, so I wouldn't want to speak to that. However, we hope to publish more testing media in the very near future!

What I can tell you is that unlike most Amazon/eBay LED headlight bulbs, we actually verify the SL1's 1,630 lumens of output in our laboratory. That is a test-proven number, not a "lumen rating" like you'll typically find.

Additionally, the optical design of the SL1 was engineered to mimic the filament location of a stock incandescent bulb, which allows a clean, OEM-like beam pattern without added glare.

We've published a series of technical videos on LED headlight bulbs on our YouTube channel, they're definitely worth a look!

They seem to be among the highest rated products on the entire site... In my personal experience, they've been excellent, absolutely destroying the other products I'd used previously, and now I use them exclusively. If there are even more powerful options out there, consider me interested.

I'll be sure to keep this thread updated with any testing we do. Claimed lumens versus measured output can be a very interesting comparison!
