Thank you so much!

 

I just bought the DE3175 for my 2006 dome lights … they are too short!

 

Even Amazon is telling me that the DE3175 31mm is the correct size for my 2005 dome lights.
It's not.
Now I'm here.
Hello.

 

The dome and map lights in my 2004 ex awd are not the same size bulbs!!
The cargo and dome light is almost twice as long as the map lights....
I am looking for the correct size for the rear cargo lights!

 

Philips 7440NA CRACKED MY SOCKET in my 2010! Connectors did not line up either!
