What's the 2009 Chevy silverado low beam bulb size?

The 2009 Chevy Silverado has an H11 headlight bulb size for the low beams. This is a pretty common bulb size and one that You should be able to find at any major auto parts store. If You notice that the headlights on Your truck are not working the first thing that You should check are the fuses to them. If the fuses are fine then it is most likely a bulb problem. To replace the bulb You will need to remove the rear housing from the headlight and then You can slide it out of the clip that holds it in place. After that You can remove the wire from the back of the bulb and install a new one in reverse order.
