Product Details

SL1 H8 LED Bulbs: Diode Dynamics came to the market with these SL1 H8 LED Bulbs and we couldn't be much more impressed. They rightly call attention to the exceptionally high build quality and reliability of these lights as well as their smartly designed hotspot and clear optics. Take a deeper dive into what makes the SL1 Special below.

Optimized Performance: We all want performance without compromise and the SL1 delivers that. Unlike other bulbs that claim insane lumen numbers, or aren't legal on the road, the SL1 Fog Light backs up its claims with clear evidence of their ability to produce brighter light (1630 lumens) in a clear and well-defined beam pattern that reduces glare and wasted light. They can manage that thanks to their in-house advanced optical design software which uses a process called 'ray tracing' to simulate exactly what each ray of light is doing as it leaves the light source and works its way onto the target. Through this process, they've ensured that every ray possible brightens up your path.

Rugged Design: While brightness is key in any good light, Diode Dynamics took exception to all the cheap junk out there that starts out bright but can't stand up to the workload of OEM lights. The SL1 was built from the ground up to meet or exceed the reliability standards of OEM lighting. It's been torture-tested from temperatures ranging from -40 to 185 degrees F. Combine that with stress relief points in the wiring harness, solderless terminals, and exclusive zinc castings and you can see why we like it so much.

Size and Heat: A major issue with the vast majority of LED lights on the market today is heat evacuation. To combat high temperatures, many manufacturers incorporate large fans or heat sinks into the bulb assembly. More often than not, these aren't even adequate enough to ensure a long life. At the same time, those large parts ensure that fitment is a pain thanks to the additional heft. Diode Dynamics works around this problem with intelligent engineering in the form of a MagLev fan that won't create interference as it cools the bulb. Because of this high-end tech, the bulb isn't much larger than the original halogen unit, allowing for easier installation and use.

Boost Mode Circuitry: In keeping with their OEM or better quality control, Diode Dynamics uses the same Boost Most Circuitry that you'd find in an OEM LED bulb to ensure that no electrical system can cause an uneven load on the LEDs and burn them out. It's even capable of handling many complex systems that would otherwise require an additional Canbus harness.

Top notch

Jeff Osgood  

Just a quality product all the way around from the heat sink to the LED chips. These put out half the wattage of the stock halogen bulbs and distributes an nice beam of yellow light. My only gripe is that make sure fog bulbs are not in at an angle (at connection). I discovered that the slf fog lights do not have an adjustable collar to be able to position the diodes at 3 and 9 to give it maximum output but it still seems acceptable. I plan on getting the SL1's for my headlamps eventually. Plus the 3-year warranty is longer than most that I've seen.

Tabs Fail !

Tim Lisle  

I ordered these Dec. 12 /18 , they cost a fortune due to the low Canadian dollar plus I got dinged for import fees , came to almost $400 !! Today I thought I'd install them . I went to twist the bulb to lock it ( H11) , the bulb kept turning . I removed it and noticed two tabs broken off . So now there useless .

This is an H11 bulb, not H8. Returning.

Sebastian Savage  

Ordered this bulb thinking that I would get an H8, but I got an H11. They should change the title because I got confused when it said "H11/H8". I was thinking they were interchangeable but be aware, they are not. Learn from my mistake. Ordering from Diode Dynamics themselves for the H8 LED fog bulb.

Really yellow!

Shaun Ryman  

Needed a small bulb to fit in my fog light housing because the washer fluid reservoir is really close to the passenger side and I couldn't fit a clunky bulb in there. Super yellow!

Andy Depena  

The SL1 LED lights were easy to install. They are very bright. Almost as bright as HIDs, without having to deal with extra wires. HR's customer service is also excellent too. Iv'e bought other LEDs from here and they honor their warranty without hassle. Thank you HR.
