If your brake lights are staying on, not working, or you're having shift interlock issues, this brake stop light switch might be your fix. This 4-pin switch directly replaces OEM part number GL3Z13480A and fits a ton of Ford vehicles from 2007-2019. We're talking F150, F250/F350 Super Duty, Expedition, Explorer, Focus, Fusion, Edge - this thing covers a huge range of models. Installation is usually pretty straightforward - typically located up near the brake pedal assembly. The quality is solid for an aftermarket part, and it comes with a 12-month warranty for peace of mind. Much cheaper than buying from the dealer, and you can often install it yourself in under 30 minutes with basic tools. Just make sure to disconnect your battery before starting the job for safety. The package includes one switch with all the necessary connectors. If your check engine light is on with brake-related codes, or you can't shift out of park, this switch could be the culprit. Always double-check your specific year and model compatibility before ordering, but if you drive one of the compatible Fords from the last 15 years, this is likely the exact part you need to get your brake lights working properly again.
