2003 GMC Yukon XL Denali Q&A
2003 GMC Yukon XL Denali Question: Do the sockets for the running lights need to be replaced if black & brittle?
If they are coming apart, yes. If they are just hard but not broken, then you should be fine. If you do need replacement, call a local dealership and they should be able to order you some new connectors.
