What is the fog light bulb size in the 2006 Tundra?

You will need to use a 9006 bulb for the fog lights on a 2006 Toyota Tundra. These bulbs will cost between $3 and $9 per bulb. Those are the lower end of that spectrum will die and need to be replaced quicker so I suggest getting the long life versions so that You won't need to worry about it for a long time. In order to replace the bulb in this truck You will need to access the vehicle from underneath. You'll first have to unplug the light and then move some latches and pins in order to pull it out of it's housing.
