The covers on mine are broke so i took the fog lamp assembly out so that i could put new covers on them and when i took them out i discovered that i bought a 893 fog light and the one i pulled out of the assembly the light said 880..Anyone know the right bulb? i looked in my book and its not there and gm parts direct doesn't list it. Its a 99 silverado 1/2 ton

 

Go to the Sylvania website. It'll tell you. Or, I could tell you I just went there and found it's an 880. It's a good website when you're replacing lightbulbs.

 

thanks
