Lema Trucking

I am having this problem in my 2021. Its not even 2 months old and im going bat bleep crazy in this cab. 
any update Deere mack? 

Yes they are 1/4 sockets. 
ill holler at mack about em this evening. 
 

New member here. Been searching high and low and cannot find the solution. 
 

I have a 2006 Mack Granite.
I need to replace the dash board lights but cannot find which bulb/socket i need. I tried pulling the bulb from the socket but the bulb I inserted did not work. 

Does anyone have a replacement part number or website where I can look up or anything that will help get my gauges visible again at night. 
 

What I removed were green Wagner sockets. Tried a 194 replacement bulb in the socket but did not work. 
 

Are the sockets and bulb one piece or am I doing something wrong?
