Installion instruction

Actually there are Instructions.. There are so Small (tiny) its not even funny. After you open the Lid they are on top of the Flaps! English is on the Top Left Flap.. ---- I Needed to Adjust the Brackets to install the Horns on my Truck and Sadly since it CANT Be seen. It tells you NOT to adjust the Bracket it affect the electromagnetical properties and will result in loss of performance and warranty.. AND I MOVED MINE! I AM Pissed off!!! I COULDN'T SEE THIS...

Are these water resistant? Like if they are on an offroad vehicle and get submerged occasionally will they still work?

These are more the water resistant. I have used this product for several years on several viechle's including motorcycles that get ridden in the rain several months of the year and have had not breakdown do to water stopping them from working. The even have been under water for about 5 minutes and worked immediately after that and several years later were still working.

Sound isn’t that deep

The sound isn’t deep it’s quite high pitched and sounds a bit stupid at first once your used to it it’s not as bad but compared to factory horns they’re really high pitched brought to replace oem part that stopped working so not bad overall

Look good, sound awful.

Took my time doing a tidy wiring job using the relay included. Making brackets to work with the larger horn. Only to find out they sound terrible and I’ll be removing them. If you need a horn to look good then buy these I just wanted a nice loud sound they are hidden behind the bumper any way.

Sounds good but doesn't last

The horn sounds loud and good but unfortunately I my experience has been the same as some of the other reviews, the horn stopped working inside of 12 montha, it seized up and blew the fuse.
