COOLEST RED HORN UPGRADE: LOVE IT

I ordered 2 units of the Dewalt Quad kit with remote and this RED COLOR HORN UPGRADE UNIT is something I really love. Sounds totally loud on Low Tone that can really catch people's attention. It came fast and was packed with total care. THANKS AGAIN BOSS HORN !!!

DIY train horn kit

This kit requires you to disable your drill!
So if you have a broken drill this works ok!
Quite a bit of modifications required.
The drill I used at the Chuck there's no way to screw back together. So a half roll of electrical tape fixed that problem!
For some reason the switch does not work, " I got the remote" .
Anyways it's so loud you don't want to be that close anyways!
In ending if your handy and have a broken brushless drill, this could save you some bucks!
Otherwise buy the complete models!

Train coming

Very loud. Great for alerting an emergency

Loud horn

Everything was of high quality. For a first timer it’s a bit difficult but not that I did it once next time around should be a breeze

UH OOH

When trying to prank my grandson I accidently made him permanently deaf and now he hates me. In all would buy again.

Hopefully you’re handy. Otherwise good luck.

I understand it’s a diy kit, but they send the parts and then say good luck. If you aren’t handy, just spend the money and buy the whole drill and horn already assembled. Otherwise, you will have a bunch of parts you can’t use. It took about two hours to understand the intent of the kit and what you’re supposed to do and to modify the inside of the drill in order to get it to work. In the end, I’m happy with the result but it was a bit of a find your own way experience.
