This red LED pair replaces 3157-size bulbs in your RV’s brake lights and tail signals. Switching to LED cuts your current draw substantially—important when you’re working with a battery bank. These bulbs generate far less heat than traditional incandescent types, making them safer for modern plastic light housings that can warp or discolour over time. The long operational life means you’ll change them far less often, reducing roadside maintenance.
