CARFKAAir Horn for Truck Boats Car, 150DB Super Loud Train Horns Kit with 120 PSI Air Compressor (black, Dual)

I thought it was gonna be cheaply made... The horns are metal and can be removed for easier installation and they are LOUD!!!! Definitely a big bang for your bucks!

This thing is crazy loud. Didn't wanna spend $300 for a pre-built drill horn online, so I bought this kit and an on sale Ryobi drill. It wasn't that hard to make, little tedious at times. There's plenty of YouTube videos to show you how. Basically just pop open the drill, clip the wire to the motor, then Dremel out the inards so that the air compressor fits, then I soldered the wires together (you don't need the relay for the drill so just hook up positive to positive and black to black). Then after soldering the wires together I hot glued the air compressor to the drill casing, screwed on the other side of the drill casing, and then predrilled a couple holes in the back to mount the horns. Overall I'd buy this kit again, the drill is exactly what I was going for and I can't wait to bring it to my siblings hockey games. Only thing is that the packaging is a bit cheap, the box came a bit smashed, but the product wasn't damaged and the quality of the air compressor and horns is pretty solid.

The kit it’s really easy to install but it came incomplete, I had to purchase the wiring and the relay

Product as described

It was cheap, felt like plastic and I put it straight in the bin
