Slip,

Gm has a service bulletin about DRL bulbs on the GMT 800 series trucks. (Which a full size chevy or GMC is). This not a recall. They specify in bulletin that the bulbs be replaced with a long life version and "both bulbs be replaced together for customer satisfaction"

The latter part of the statement is where their is a lot of misunderstanding, I have seen many times only one bulb replaced and then a short time later the other burns out. Replace both bulbs with trade #4114K the old bulb trade #4157K. The GM number if needed is 15199562
