I was as careful as possible not to touch the bulb while replacing it, but I concede these halogens don't last forever, so it probably won't be long until I have to replace the other side. So I have a spare one in my kitchen ready to go. It's fine Walmart didn't have the one pack or the cheapest bulb. I spent $25 rather then $10 on one bulb. Maybe the color or brightness is a bit better on the more expensive bulb, not that I drive that much after dark.

Those headlight bulbs don't last a long time on the Silverados. I think I get 3-5 years out of them on average before I end up changing them. It's not a difficult job but it's still annoying to have to do it after a very dark drive home -- you don't realize how crap the light is out of only one headlight. Plus, I bet the other headlight is far below it's peak brightness, and I got two bulbs but I haven't replaced the other side yet.
