I did this on my cobalt...

To start you need to remove your foglight projector and get an LED strip. I chose blue for mine but you can obviously do any color.



Then you trim the LED strip down so it will fit without overlapping at all. I ended up cutting my strip in half.



Next you drill a hole in the projecter housing and feed the LED strip thru and secure it in place using double sided tape.



As you can see I also put a rubber grommet in as well to help seal...Before I actually install them onto the car I will but a bit of silicone in to completely seal it up.

Make sure everything is in place and test it out!



Here it is in the dark...



I have no idea how this will hold up over time, but I had an extra set of foglight housings so I figure wth. It's worth a shot! I'm about to go to bed so I'll update later today when I get everything put in. and then pics once night falls :)

And here are the installed pics:

Here they are installed:




And then with the fogs on:



So if you don't know and can't tell what a 'demon eye' mod is. It's when you put a colored LED ring into a projector housing to make it glow that color, but you are still able have the normal use of your light.

 

Looks good. It would be fun to do something like this to my Depo's and standard Fog lights..

 

f..king! .. very cool!
i must make himself such demonic eyes
thanks for the tip

 

Thanks for the props guys! I'll try to keep you guys updated on how well they hold up over time.
