Nothing beats a well-timed movie quote coming out of your car at 130 decibels. These are the ones people recognise instantly. Two classics we've covered in full: the Godfather car horn and the Jeepers Creepers horn.

Three words. Instantly recognisable. Works every time someone cuts you off.

2. The Imperial March . Star Wars

Pull up anywhere and let Darth Vader announce your arrival. Especially good in a parking lot.

130 decibels of dinosaur. People will genuinely flinch, it's the same energy as the monster roar horn.

4. "Get to the Chopper" . Predator

Arnold Schwarzenegger at max volume from a moving vehicle. There are no downsides.

5. The Price Is Right Losing Horn

Perfect for honking at bad drivers. The sound says everything you're thinking.

Animal Sounds

Animal sounds are some of the most popular custom car horn sounds out there. They catch people completely off guard.

6. Goat Scream

Deeply unhinged. Works on both strangers and people you know.

Music Drops and Sound Effects

These are the ones that turn your car into a moving joke that people film and put on social media. For an all-time classic that fits right in here, the La Cucaracha horn is hard to beat.

10. Classic Air Horn

A DJ airhorn layered over a bass drop. Makes any parking lot feel like a festival.

Sounds from Your Favourite Shows

The dun-dun-dun-dun sound that plays when something goes wrong. Perfect for traffic.

19. Your Dog

Record your dog barking or making noise, convert it to MP3, load it up. Your car barks at people now. That's just brilliant.

20. Your Own Voice
