Comment on YSK that if your turn signal is blinking unusually fast (like 3 or more times a second), it generally means you have a bulb out.

I don’t believe so. The clicking is from the bimetal strip that flexes due to electrical resistance heating up the strip and repeatedly breaks then connects again as the metal cools and makes contact. A blown fuse would not send electricity to the blinkers to cause the rapid blinking. The reason it blinks faster with a blown bulb is there’s more voltage to the strip so it heats up faster and breaks the connection sooner but doesn’t allow it to heat up enough to cause a longer off delay.

Not as much any more. Most vehicles now just play the sound over the driver’s door speaker. The blinking is a PWM. Lack of current draw results in the PWM firing faster.

  I figured my knowledge was outdated since mechanical solutions don’t exist as much anymore.

    Same here, but no harm. That was how it was done!
