GMC Canyon AT4 SeaLight LED Install & Review

Installed some Sealight LED bulbs into my 2021 Canyon AT4, and figured I would share the process with everyone. The stock lights are horrible, especially at night, and the factory yellow color is hideous. Upgrading the bulbs to proper LED's not only makes the truck look more modern, but also helps visibility. I highly recommend these bulbs, especially if you can get them on a sale like I did ($60 including tax). One of the best bang for your buck mods on the market for the Canyon / Colorado GM twins. Comes with 4 bulbs, 2 for the high beam and 2 for the low beam, direct plug and play.

Thank you for scripting, photographing and producing this incredibly informative and helpful step-by-step video. Closely followed each well planned and explained movement. Guessin' it took me a bit longer than most. Was rewarded "to-the-max" when seeing the incredible lighting improvement. Awesome video! Thank you!

Sad GM doesn’t include the LEDs for the AT4 headlights. Great detailed review on installing

[zachrandolph]

Amazingly helpful video . Looks great on mine . I didn’t have to unplug the horn I just sort of pushed it off to the side and it worked

Just got a 2021 Canyon and these are the exact lights I was looking at buying. They seem like a no brainer for the price!

So my dad’s looking for led bulbs better than the halogens on his 21 at 4 canyon.Are these really good and better and are they really bright

I bought the X1 Sealight bulbs for my 2022 GMC Canyon AT4 like you installed on your truck. I was not satisfied with the SeaLiight X1 low beams so I bought the X2 fan cooled version and they are absolutely spectacular. Way brighter and much more down range powerful. The X2 versions have much more projection power and I'd say they are 50% more brighter. They are fan cooled of course but that's okay with me, I'm very satisficed with the X2's and just as easy to install.

Than you. Just changed mine out on my 2022 Canyon Denali. It was as easy as you made it look.

Thank you for this very helpful video. I ordered the same lights and installed them yesterday. They are great and the look is so much better. Thank you!!

Thanks for the video! I just picked up my Canyon AT4. I went to order these and there is a 50% off coupon running right now as of 7/2/2021

Thanks again for the video, these led lights do indeed work on a 2021 Gmc Canyon elevation, boom!

[micYT]

Thanks!! This process worked on my 2021 Canyon. Only concern I have is the ballast not staying stuck to the inside of the housing and dangling free at some point.

I was hoping you might remember a few things about this install. I just bought these and had a few questions about about some things…

Did the High Beams LED’s have a bit of play when you rotated them in? Mine have a slight wobble compared to the factory lights that were very snug. Interestingly the low beam LED’s were very snug as expected.

And have you had any issues with heat and melting? I read reviews for some people that said they got so hot their wires were melting or housing has melted a bit. Some people also mentioned flickering.

Thank you for a great, well thought out, perfect lighting, camera work and video..
You did a great job!
Can you please tell us if the Low Beams Light Output down the road in the dark is the same as the Halogens you took out ??
I drive a lot at night and need the Low Beams to reach out as far as possible, before I have to use the high beams..
Sometimes, high beams are so bright, they light up Every Reflective highway sign on the side of the road, so this is why I want the Low Beams to be really out there as much as possible..
Thank you again !

They look great! I just installed morimoto 2stroke 3.0s in my 2018 Canyon low beam and they don't work. Well they do in park but as soon as I put it into drive they go out. Trying to reach the co I got them from now. Any suggestions?

[dwlubu]

does your DRL flicker? if not and works properly, is it running at 30% brightness or 100%?

[Mykantana]

I like the way you trimmed that air damn down. Looks a lot better. Did you make a video/link or instructions on how you did that? I’d like to trim mine.

[Zac_B_AZ]

Thanks for the video! Just got the AT4 and will be making this change.

Any other (relatively) easy mods you've done or looking at doing?

[antcar]

Please post the model number for your lights, when I look on Amazon it says “ not for your vehicle “ 2021 AT4 thank you great video,

[joemoore]

Would these work for a 2016 canyon? The standard yellow is just completely awful and been looking for some good LEDs.

[codhackzWII]

Are they brighter than the stock yellow?
