The driving lights on the Yukon XL Denali, what do the lights closest to the grille used for. Ive tried everything. Hazards, bright, dim, fog lights on but when are they ever on. These are the lights right below the head lights and there is three lights on the running lights. The two are used for turn signals and driving lights but the 3rd light closest to the the grille when does that turn on and how do you get it to turn on. Please reply because its driving me insane. Please help
