I searched this on multiple forums and everything was kinda meh!!
So this is for 02-03 impreza/wrx (not sure if other cars are different)
I believe there is more than one way to do this,but here's what I did.
-Open glove box and remove 7 Phillips screws there is 2 under the glove box. Also remove plastic clip on the right side of glove box behind the door.
-Wiggle it out slowly as there is a wire connected to your glove box light.
Some people can squeeze there arms up there but it really only takes a minute to remove it.
-Simply pull out the clip that my screwdriver is pointing at,tape those puppies up and that's it! No more DRL!
Note: it is illegal to have no day time running lights if your car was originally equipped with them.(I think)
