The front turn signal lamps are always lit when driving since they are the
new generation daytime running lamp (DRL). I see 4-5 GM cars on the road
each day with one front turn signal DRL burned out. Friends/coworkers
complain about the same thing....including the charred sockets you mention.
Very common....get used to it. The Sylvania long life's may help some,
although the OEM bulbs are *supposed* to be the extended life type as well!!
