Everyone loves a cool-looking set of GMC Terrain fog lights, but we also recommend them as a safety item for times when visibility isn't the greatest. If you do a fair amount of driving, you'll appreciate the peace of mind in knowing that your GMC Terrain fog lights will be there to help light the way on a gloomy night. And yes, installing a set of fog lights looks a lot better than having empty holes in your GMC Terrain bumper!

Fog lights usually work best when your GMC Terrain headlights are off, but because of many road laws they are often wired to work in tandem with low beam headlights. In general, yellow (officially known as "selective yellow") GMC Terrain fog lights are more effective in adverse conditions due to the reduction in short blue light waves present in white lights, which can distract the eye and make it more difficult to see detail. Most GMC Terrain fog lights are actually universal mount, but others are available with application-specific mounts and harnesses which plug in directly to your GMC Terrain wiring harness.

Q: Do foglights come with everything I need to install them?
A: Yes, the car-specific fog lights we sell come with a plug that is made to interface directly with your factory fog light harness, so you would literally just plug them right in when you get them and you're set to go. For the universal foglights, or if your car does not come stock with foglights, it takes a little more work. You have to go down to your local auto parts store and buy a fuse and an on/off switch, and using the foglight wiring you wire the foglight to the fuse, which is connected to the battery. It is a do-it-yourself project, but just takes a few more steps.

Q: Why buy fog lights?
A: Aside from replacing a broken factory foglights, buying foglights can be a great way to give your car a custom look. You can buy foglights with a different color than your factory foglights or that are brighter than your factory fogs. If your car doesn't come stock with foglights, then buying foglights can be great. Not only are they a great way to customize your car, but they of course also have the obvious safety features that make driving safer when you use them.
