Build Guide?

[giganova]

Hi all --

I have a 2021 RAM 1500 (new model) and made the mistake of replacing the upper cargo and third break lights with LED lights. Now I am getting a frequent "key fob not detected" error message and shortly after I installed the bulbs, they stopped working altogether.

Can someone tell me which bulbs I should buy? What are the stock bulbs? (I threw mine away and don't know what bulbs are stock)

Thanks!

Sylvania's website has a complete list by model.

They do have LED light bulbs that work with our Rams CanBus system

What is canbus error free LED?

CAN-bus Error Free LED bulbs are LED bulbs that have resistors that are internally/externally attached. ... The resistor's job is to mimic the power draw of the stock incandescent bulbs to trick the computer to think that the bulbs are drawing the same rate of power so the vehicle does not throw any error messages.
