Review on 📢 Powerful Hadley Horns H00964H Black Underhood Horn Kit - Enhanced Vehicle Alert System by Ray Reeltalk

Installed on a 35ft diesel van. They are incredibly loud for their size. Generally very happy with them. I made a custom mounting plate and wired it to an internal switch to bypass the pressure switch that turns the compressor on automatically. The compressor is a bit noisy when running - the good news is that the air tanks fill up quickly and the compressor doesn't run very often or for very long. The kit was very complete with all parts needed (except for a custom steel bracket which I made for my application).
