I just recently purchase a used 2012 300 Limited. I noticed that the passenger high beam is not working. Is the high and low beam in the same lamp or is the high beam a separate lamp? Also, what is the lamp number to replace it with? Thanks.

 

I can't believe nobody has responded. Must be too difficult of a question.

 

You should check your owners manual, however my 2013 with Halogen lights indicates it is one bulb. HIR2LL.

The dealer replaced the high beam bulb and still not working. They ordered a complete new headlight assembly. Good thing this is covered under warranty. They are replacing a module for the hands free bluetooth which also is not working.
