Fog lights didn't work

Have a 2015 Tundra SR that didn't come with fog lights. I got some used ones, plugged them in and nothing happened.
What should i try?

 

Double check your switches... make sure highbeams werent on by mistake

 

Check to see if there is a fuse for fog lights

You added the new light switch with the fog light switch right?

 

It's like this one. For high beam i push or pull. For the fog I'm supposed to turn it.

 

Not really all that car smart. Where in the fuse box will it be? Does it have a specific number?

 

You may not have one in there jf it wasnt equipped. Look at the cover for location. Go to carparts store and buy the matching amp rating

 

A what? Fuse?

 

You said the fog lights are used? Sure they're good?

 

yes a fuse.. look at the attachment in #8 you should have a fuse and a relay somewhere.

 

Also the headlights need to be on for the fog lights to come on as well.

 

you need the relay..@Roman could hook you up. for my 2017 sr I just had to get the relay, ground a wire to the frame. They come on and off with the headlights..
