Technology Connections explains why car turn signals appear to drift out of sync at stoplights and how thermal and other flasher designs work. It also covers how synchronization could be achieved.

Why Hacker News points people here: Referenced as a typical example of the channel's hacker-eye view of everyday technology, and for its flasher explanation.

Why turn signals don't sync at stoplights

Full comment

Came here to post this :D The TC channel is definitely a hacker's eye view in to all the technologies that we take for granted every day. Tons of fascinating tech history covered, too. Other fun ones: - a defense of the simple drip coffee maker link - why do the turn signals not sync up when you're at a stop light? this video - how humidifiers work and ehy the simple swamp cooler style are pretty ideal link - why dishwasher detergent packs are stupid (use powder/liquid) and why you should use the pre-wash slot and not bother pre rinsing your plates link - why do light switches click? link

please please don't: this video I refuse to drive at night anymore. Headlights are way too bright and a big reason is people putting poorly made and poorly aimed aftermarket headlights on.

Demonstrates thermal and capacitor-based flashers

There's a video by Technology Connections all about turn signals: this video Demonstrates thermal-based flashers as well as capacitor-based flashers. They are clicking because metal is moving and hitting metal.
