My 2021 RAM Limited 2500 has incandescent light bulbs inside the Ram Box, why? All the lights in that vehicle are LED. The bulb size is 194 and I ordered four LED bulbs off of Amazon. Luyed is the brand name and they are CANBUS ready, so there are no codes or error messages. This is the only brand LED I have ever used on my Dodge products without issue. The install is easy and straight forward. Remove the light housing, I use two small screw drivers. You will see a small black tab on the housing. Slightly push that up with the tip of one screw driver and the use the other to gentle pry the housing out. Pull the old bulb out and slip the new LED in. Replace the housing and your finished. As a rule of thumb I always wear a rubber glove when handling the light bulbs to prevent any oils from your skin coating the bulb, they will pop if they get hot and there is oil on them. A link to the bulbs I purchased is below.
