This video demonstrates the installation steps of Diode Dynamics SL1 LED Headlight bulbs on a 2014 GMC Sierra 1500. The SL1 LED Headlight bulb is engineered to perfectly mimic your Sierra's stock beam pattern while being FAR brighter and more focused. The result is dramatically upgraded visibility, and a much more modern look, thanks to the 5700K "cool white" color temperature.
Unlike generic LED bulbs, the SL1 features an advanced optical design that allows for increased light output with zero added glare. As shown in this installation video, the SL1 LED Headlight Bulb is 100% plug-and-play, with NO splicing or wiring needed. The bulb and driver tuck neatly inside the 2014 GMC Sierra's factory headlight housing without any modification.
We proudly manufacture the SL1 right here in the USA. And as with all Diode Dynamics LED lighting upgrades, the SL1 is backed by a 3-year warranty.

Thank you. This video is straight to the point and easy to understand. I successfully changed my lights on my truck with no issues.

[@diodedynamics]

Glad that we could be of help! :)

[@scotland8]

Thanks so much for the video, I’m a pretty handy guy and am ok with basic vehicle maintenance, but had to say removing emission filter system to change a bulb it’s pretty interesting. Thank you so much really helped and save me about 200 bucks!

[@diodedynamics]

There are definitely many different ways to go about installing these! This was the way that we felt was most efficient for our application!

[@jbraz8]

Hey wanted to say thank you. Got the driver side done, then went to do the passenger side and said "Where's Uncle KZbin'' It was very easy to follow, thanks again 🙏

[@diodedynamics]

Glad we could help! 🙌

Great video, just ordered a pair. Can’t wait to get them in.

[@diodedynamics]

Thanks for your support, Scott!

[@508knucklehead]

How are you liking them? I have to replace my LED headlights every 8 months or so.. never used this brand

[@DavidTorres-tw8kv]

Thank you

[@diodedynamics]

You got it!

[@ptre8828]

Would of really liked to see a before and after.

Pastor Rec it’s at the very end

[@danielstrunk1825]

Is it safe to do this with no real place for the bulbs to vent?

[@diodedynamics]

Absolutely! These bulbs were designed to function for over 40,000 hours in sealed headlight housings.

[@forgedcustoms5699]

Is there anyway you can do this without removing the air box?

[@diodedynamics]

From our experience, to gain access to the back of the headlamp, the airbox must be removed!

[@smokymountainoutdoorsman1991]

Will these also work for a 2015 Silverado 1500? If not, why?

[@diodedynamics]

Hey there! They sure will! Check them out below! www.diodedynamics.com/low-beam-led-headlights-for-2007-2015-chevrolet-silverado-pair.html

[@christiantapia743]

Did anyone have a check engine light on afterwards?

[@diodedynamics]

No check engine lights with these bulbs!

[@NORTHERNRUCKUS]

Yes, I did.....I think its cuz we messed with the air filter and sensors..... thanks GMC

[@mrmarkusgoat9631]

Hello Diode, I changed my stock headlight bulbs to LED & my check engine light came on, any suggestions on why & what I can do to make it go out w/o going to the dealership?

[@jhanick]

Same thing happened to me. Currently troubleshooting by removing battery ground for 20 mins

[@alexpat2502]

Did unplugging the battery work for you guys?

[@mrmarkusgoat9631]

@@alexpat2502 It went out as I was driving & it never came back on. Thanks

[@jhanick]

@@alexpat2502 yes. Unplugged ground for a few minutes and plugged back in, started up and no problems since.

[@josephmercer8101]

Had the same issue, turns out it was air getting in around wear your air box and flex hose meet. Unmetered air will do that. Double check all the connections between the throttle body and air box.

[@MrJunior6939]

Those Leds can damage my bcm in my 2014 GMC Sierra ?

[@diodedynamics]

Hey there! Are you asking if they will damage it , or are you saying that they somehow did damage it?

[@MrJunior6939]

@@diodedynamics yeah if they will damage ...the question is because months ago I install different 9012 Leds in my truck and supposedly they damage the bcm but I bought it in Amazon

[@diodedynamics]

@@MrJunior6939 We've never heard of these damaging a BCM. However, it is important to note that we no longer offer these as headlight bulbs. We recommend them for foglight use only.

[@MrJunior6939]

@@diodedynamics well In this video talk about headlights not fog lights .. headlights bulbs are 9012

[@buzzsaw5]

Overkill on the passenger side. All you need to do is loosen the hose clamp and disconnect the MAF sensor harness. Slide the tube off the airbox and then rotate the entire airbox assembly up and out from the end of the tube you just disconnected.

[@mikeleo5990]

Hey buzz make a video of your method - I’m the kind of guy who’s gonna break 2 other things to fix 1 bulb lol.

[@viramontesjr9203]

Thanks boty

[@MrTargetU]

so just skip over the part of aligning the diodes? And the part about adjusting the collar if not correct? Yeah, well either way it doesn't avoid the shadow effects on the projector. This product is insufficient for this type housing

[@diodedynamics]

Hello! We have found that adjusting the collar of the SL1 is not required for every application, so we created a separate video covering that. As shown in the video, the SL1 is a definite upgrade, compared to the stock Halogen bulbs. If you are having issues with a set, or if you have any other questions, just give us a call at 314-205-3033, Monday-Friday 9 a.m.- 5 p.m. CST, or shoot us an email at [e-mail]!

[@richardconnell7118]

Good video, but safety first, no jewelery.

[@diodedynamics]

We appreciate the feedback!
