Before you begin
If your brake/tail light on your 2006 GT Ford Mustang isn’t illuminating and needs to be replaced, use this guide to replace the lightbulb. The brake/tail light illuminates when the headlights are turned on to create visibility for drivers behind you during the night or adverse weather conditions. A burned out lightbulb will be very dim or not illuminate at all. This can present danger to yourself and other drivers, or just get you a hefty ticket from law enforcement, so use this repair guide to restore safety and legality to your vehicle. Before using this guide make sure that your brake/tail light is actually not illuminating. The car should remain turned off for the duration of the repair!
