24v TGV Train Air Horns | 24 Volt Chrome
These 24v horns simply connect into your airline and produce a very loud output (125dB). They come with bracket and relays already connected. They alternate the sound between the two horns to give the TGV train sound effect.
They alternate the tone approximately twice a second.
Note: These horns need an airline to work, so need to be fitted to a suitable vehicle.
