ive only seen the led do,e lights work one way. the regular dome lighte work both ways.

 

I'll try turning the dome light around. Also, discovered the speedometer only goes to 35 miles an hour. Seems to track the miles alright though.

Tried the toothpaste but must not be doing a good job as I can't see an improvement. Will get the 3M restoration kit and use my electric buffer.

 

Have been gone but my light is cigarette shaped and the same connector on both ends. Don't know what a festoon light is. Sorry for my ignorance. The weather is supposed to turn warmer here so will work on it again tomorrow. Plan on buying extra fuses for the PDC & Fuse box both.

 

Just looked at the Interior Lights electrical diagram and noticed that the only fuse for the dome light is located in the PDC and is a 5A for fuse F2. Will purchase a new one before going home for the day.
