What is the 2017 chevy traverse fog light bulb size?

The 2017 Chevy Traverse comes with a H8 size fog light bulb. This is a very common size bulb and You should be able to find it at most auto parts stores and big box stores around the country. When Your fog lights are not working the first thing that You should do is check the fuses to them. If these are in tact and the lights still do not turn on then the next thing to check is the actual wiring at the back of the fog light housing. If this is loose or damaged it can prevent them from working as well. If both of those things are fine then it is most likely a problem with the bulbs and they will need to be replaced.
