The Lexus RX350 Turn Signal Flasher helps protect communication on the road by rhythmically blinking the indicator lamps to let nearby drivers know your next move. In every RX350, this relay is located in the fuse box and when the stalk is moved, sends the current through the Turn Signal Flasher to pulse the bulbs in a steady pattern. Earlier RX350 models had a thermal Turn Signal Flasher in which heated spring steel bent to make and break contact, and the blink and the click came from this. Newer versions of the Lexus use an electronic solid-state Turn Signal Flasher with a timing chip that pulses the lamps and can handle the low current of LED lights without speed errors. Drivers experience no change, and the life of the solid-state unit is longer, it remains quieter and maintains flash rate steady even if a bulb fails. The trick to selecting the correct Turn Signal Flasher is that you must match the build year, bulb type, and connector style so that the RX350 indicator circuit works flawlessly. Overall, the Lexus Turn Signal Flasher is inexpensive and durable, but its task is crucial for keeping your Lexus visible, audible, and predictable in traffic.
