Your front DRL bulbs 4157 keep burning out within 1 month What if the original bulbs lasted 5 years What is the correct part?

The problem I have had is the base melting and charring of the contact from the resulting loose connection. This seems to be another common problem with intrigues and other similar GMs. I have found that using Sylvania bulbs hold up bestter than GE and others. My guess is the base material has a higher melting point. Be sure and clean off the contacts in the connector and inspect for damage, else you will fry the next bulbs in short order. I have heard several instances of tail lights and driver lights on other brands as well as GM having overheat problems.
