Lexus/Toyota Turn Signal Problems

That's a great detail to know! The fact that the turn signal blinks for a few seconds and then goes off suggests a specific type of issue. Here are some potential causes:
1. *Worn-out or loose turn signal bulb*: The bulb might be on its way out or not making proper contact, causing the intermittent blinking.
2. *Faulty turn signal flasher unit*: The flasher unit regulates the blinking speed and duration. If it's malfunctioning, you might see irregular blinking patterns.
3. *Electrical issue or short circuit*: A temporary electrical glitch or short circuit could cause the turn signal to blink erratically and then shut off.
4. *Turn signal switch or lever problem*: The switch or lever might be worn out or damaged, causing the signal to malfunction.
It's important to address this issue as soon as possible, as it can lead to safety concerns or even a citation. You may want to consider consulting a professional mechanic or a Lexus dealership for assistance. Let me know if you have any other questions or need further guidance!
