Having brake light issues on your Citroen, Mitsubishi, Peugeot, or Toyota? This little switch might be the culprit. The SDYYDS Brake Light Switch is a direct replacement for part numbers 453468 and 84340-69075 (among others). It's a 4-pin, plug-in style switch that operates on your car's 12-volt system. When you press the brake pedal, this switch completes the circuit and tells your brake lights to turn on, alerting drivers behind you – super important for safety. It's made from a mix of durable plastic and metal, so it should hold up well to constant use. The green housing makes it easy to identify. Installing it is usually pretty simple; it's often located up near the top of the brake pedal arm. Just unplug the old one, swap in the new, and you're back in business. Fits a range of models including the Citroen C-Crosser (2007+), Mitsubishi ASX and Outlander II, Peugeot 4007, and Toyota models like the Avensis Estate, Prius, and RAV4. Keeping your brake lights working properly isn't just about avoiding a ticket; it's about making sure you're visible on the road. This is an affordable, reliable fix that can save you a trip to the mechanic.
