Key Fobs and LED interference

Can you send info for rubber seal, I want to also replace seal. Thx.
Sure, this is available at Home Depot. It takes time and goo gone to clean the foam off the cargo and stop light fixture, but I doubt I will have a leak problem now, not that I did before.

 
This is the one you want to get

M-D Building Products 19/32 in. x 10 ft. EPDM Cellular Rubber Auto and Marine Weatherstrip
 
I replaced the old Lasfit bulb with the new version and no issues. Then again, I didn’t have any issues with the previous version.

New version photos below:

So Lastfit haw two different 921 bulbs and each come in red and white. They’re descriptions on Amazon and their website differ on which is used for the cargo or brake light. Can some of you who’ve used them successfully confirm if you used the larger silver bulbs or the smaller gold ones? Or a combination of both? Also to confirm if we are getting the new updated bulbs do we need to buy directly from Lastfit or is the Amazon stock updated as well? Thanks.

The bulb I have in my post above yours is the new bulb and is available directly from Amazon. I found it to be less expensive than ordering from Lasfit.
The bulb is for the 19/20/21 Ram 1500 DT, is red when illuminated and works perfectly.

Below is the OLD style...you need the new style in my post above:

Thanks. Did you replace your cargo lights as well?

No. Lasfit has indicated only the 3rd brake light bulb needs to be replaced with the new version. If you have the old version, call them and they will give you a discount on the new one.
 
Why would led bulbs cause interference with the key lol this makes no sense lol
Led bulbs operate off a radio frequency that can interfere with other radio signals

I notice it’s either the brake light or bed lights. If bed light is on, I just manually shut it off and I’m good to go.

I spoke to soon on my Lasfit Cargo lights. If I open the door and the cargo light goes on, then without closing the door I press the start/stop button, it gives a Key not Detected. If I close the door, no problem, if I turn off the cargo light by pushing the button on the light switch, no problem. So what is the fix for that?

Yes, it is all 3, the brake light and the cargo lights. Lasfit may not have issues with their LED’s in other brands but it does cause problems in the RAM trucks.
 
I just traded in my 2020 bighorn which had lasfit led’s in the cargo, 3rd brake light, all interior, and reverse light positions. I never once had any issues with interference. I’ve got the lasfit 3rd brake light led in my Laramie now and haven’t had any issues so far. The cargo lights should be here in a few days and I will report back if I encounter any problems.
