Has anyone swapped to LED bulbs for the third brake light/cargo light on a 2021 Ram? I have seen a bunch for 2020 rams but they say it won’t work for the 2021

I don’t see why they would work for 2020 and not 2021. 2021 does have two versions of the 3rd brake light, a carryover from 2020 and the new LED version that houses the camera for the digital rear view mirror (new technology group).

the problem is the led bulb interfering with key fob transmitter which is located right next to the center brake light. You can switch the cargo to led and shouldn't have a problem with your key fob. Some folks use diode dynamics led bulbs in the center brake light and were fine.

I have tried lasfit and diode dynamic lights in my trucks 3rd brake light and all of them gave me issues. I kept getting interference with the key fob and my passive entry buttons on the outside door handle.

There is a full thread in here of people swapping the factory 2021 LED third light into 2019-202 models. Some got it to work, others had issues. The camera needs wiring which is a pain, the upgraded mirror and programming. Hit or miss.

Try out the updated LasFit bulb for these. It is T-T15R. I was one of the trucks that had an issue with the frequency interference, and this updated bulb fixed my issue.

Colorado and Texas.

Diode Dynamics and SuperBrightLeds apparently don't cause the interference.

Has this been confirmed for the 2021 models? My 2019 had the Lasfits with no issue but not sure what to do with my 2021 now.
No that isn't confirmed. Me and some other members with 2021 Laramies tried diode dynamics and lastfit bulbs and they caused key fob errors and passive entry buttons wouldn't work.

Thanks! So really our only option is the OEM LED one for $350

Unfortunately if you want a flawless LED install for a 21 Laramie it seems the OEM LED is the way to go. You can install LED bulbs and put ferrite chokes on the wires which reduces interference but this won't make it perfect either. I still go back and fourth on using cheap LED bulbs with ferrite chokes and the OEM LED. Would be really nice if another company started making some aftermarket LED 3rd brake lights for these trucks.

Yeah the OEM does look really good especially with he addition of the rear view screen. May just wait and go that route later. Not sure why we don't have an aftermarket high mount option yet as the trucks been out for 3 years now.

Spending $350 for an led bulb vs incandescent? If you do this you have issues or money to burn.

I just installed the Lasfit RT15 (cargo) and RT15R (3rd brake) LED lights. Thus far I have zero complaints and work in perfect synchronization with the fob, brakes, door sensors. Granted I’ve had them installed for 3 days thus far, but zero complaints. Super bright! Full disclosure, I was sent the lights from Lasfit. If you decide to give them a go, code RAM10M gets you 10% off. I also do not profit from the code. Help that helps and good luck!

What are your truck specs? Year and trim level?

Probably won't help many people on here but if you're in Alberta (specifically Calgary), Big6ix Industries is an LED company that hooks it up. Got my 3rd brake light swapped to LED and not a single issue. My brother did a full LED conversion on his 2018 Sport a couple years ago now and so far so good. They're just a small start up company, can find them on Facebook and I'm sure Paul can work something out as far as shipping goes. $20 and I got a set of 4.
