Detailed Description

Standard Ignition BTL100 is a center high mount stop light designed for GM full-size SUVs that use the specified rear liftgate or light assembly configurations. This part cross-references Dorman OE Solutions 923-203 for the same application. If you are replacing a leaking or deteriorated third brake light seal on a Chevrolet Suburban, Tahoe, or GMC Yukon, BTL100 provides a direct replacement path with the correct connector and terminal layout for the listed vehicles.

Use this part when the original third brake light gasket has dried out, when moisture is entering the rear lamp area, or when the stop light assembly is no longer sealing properly against the body. Standard Ignition BTL100 is also a practical replacement for technicians servicing Chevrolet Suburban and GMC Yukon rear lighting repairs where OE-style fit and electrical connection are required.

What It Helps Fix

• Water intrusion around the third brake light housing
• Dry-rotted or deteriorated OE gasket material
• Brake light failure caused by moisture exposure
• Poor sealing at the rear stop lamp assembly
• Electrical connection issues at the center high mount stop light

Installation Notes and Tips

Verify the vehicle’s rear body style and lamp configuration before installation. Confirm the connector shape, connector gender, and terminal style match the existing harness on the vehicle. For best results, inspect the mounting surface for corrosion, old seal material, or debris before installing the replacement light assembly.

Quality Assurance

Standard Ignition states that this replacement is engineered to meet or exceed OE performance, with a focus on proper sealing and dependable operation for the listed GM applications.
