Product Details

SL1 9012 LED Bulbs: Diode Dynamics came to the market with these SL1 9012 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.

Diode Dynamics SL1 9012 LEd

Roberto Martinez

I would have give this 5 starts but one of the led showed up dead. I tried everything to make sure the polarity wasn't wrong but it turned out it was just a bad led. On top of it being a bad led the housing to connect it was not sliding in as it should.

2015 GMC Siera with projector lights


I finally found the right LED's! Have tried a couple other LED's that were horrible and also had an HID set that was good but unreliable, and had difficult installation. These are finally focussed correctly and are almost as bright as the HID's. 100% suggest them - they cost more but they work, are built well, and install with a simple plug n play!

Ok quality excellent customer service


Purchased these LEDs to replace projector halogens in a Buick Regal turbo. First set of LEDs the housing wasn't completely sonic welded together which allowed for play in the light position In the projector housing. This created a dark spot where the hotspot should have been, and overall the bulb was a 3/5 brightness compared to the other side. After reaching out to headlight revolution they had another pair at my door the next day. Now both hotspots are bright and subjectively I'd say it's twice as bright as the halogens. Good choice for projectors. Fantastic customer service from headlight revolution.
