Dorman Brake Light Switch for Dodge/Ram/Viper — Direct-Fit Replacement (select years) Restores Brake Lights & Cruise Control

The Dorman 901-275 is a direct-fit brake light switch designed to restore brake-light operation on select Dodge, Ram and Viper models when the original switch fails.

If your brake lights are intermittent, staying on, or your vehicle’s cruise control and shift-interlock behave oddly, a worn or failed brake light switch is often the cause. This replacement unit is engineered to match the original switch’s fit and function for specified Dodge and Ram model years and Viper applications, making installation straightforward for DIYers and professional techs alike.

Will this switch fit my Dodge or Ram?

Compatibility is limited to specific model years and trims; always verify fitment before ordering. Use your vehicle details in the garage or fitment tool to confirm that this part matches your year, model, and trim.

• Compatible models include: 2010 Dodge Ram 1500/2500/3500/4500/5500;
• Also fits Ram 1500 (2011–2012), Ram 2500 (2011–2012), Ram 3500 (2011), Ram 4500/5500 (2011);

How does this replacement restore vehicle functions?

The switch reinstates the electrical signal that tells the vehicle when the brake pedal is pressed. That signal controls the brake lights, informs the cruise control system, and engages the shift interlock so the transmission operates correctly.

• Re-establishes brake-light illumination for safety;
• Restores proper cruise control disengagement behavior;
• Allows correct gear-shift interlock operation to prevent unintended movement;
• Eliminates intermittent electrical faults caused by a failing switch.

How difficult is the installation and what should I expect?

Installation is generally straightforward and designed to mirror the original equipment for an easy swap. Basic hand tools are typically all that’s required, and many installations can be completed in under an hour by someone comfortable working under the dash.

• Direct replacement—no modification to mounting points or wiring expected;
• Common tools: screwdrivers and a socket set or wrench;
• Disconnect the battery as a safety step before beginning work;
• Check operation after installation to verify proper engagement and light activation.
