Why do cars still use mechanical blinker relays?

Question

I think the electronic relays may be cheaper; and having less moving parts they are theoretically less prone to break.

So, why do cars still use mechanical relays for turning lights?

Answer 1

I can think of several reasons straight away:

• Cheap
• Easy to replace
• Have a very distinctive click that makes it obvious when they are on, and when a bulb has failed
• Are very well understood
• Anyone can fit one without needing to understand much about electronics
