Bruder Toys - Attachable Realistic Light and Sound Module with 4 Different Siren Functions (Police Yelp, Engine Noise, Police Siren, and Fire Engine) - Ages 4+

Easy to install and works great. Kid loves the sounds. I am sure the extra caps will get lost so I just had him pick the color he likes best and assume that's what we'll always have on there, but it was easy to pop them on and off if you want to switch it up.

The siren and lights are a good addition to any of the Bruder trucks. It has four buttons on top: truck idle sound, horn, siren with lights, and blinking lights. It installs in seconds in the roof-top on any Bruder truck. The only trick you need to remember (not in the instructions) is that the color lamps twist off counter-clock-wise to install your choice of blue or amber.

This is perfect for more realistic play with Bruder TrucksPros:-Easy to install, just press and click.-Add a more realistic gameplay for kids, lights and sirens galore.Cons:-Buttons are kinda hard to operate for younger kids, its also located in a low profile location at the sides.Bruder Trucks are one of the best Toys for young boys and having this as an attachment makes game play more exciting.

09/19/2017 Bruder Customer Service helped me get the original Module for the Scania Liebherr Crane Truck. The original has:Siren, Engine, Horn & Lights.This new module has:Engine noise, Police yelp, Police siren, Fire siren...more appropriate for Emergency Vehicles.Original Review:This module did not have the original functions for the Scania Liebherr Crane Truck. It has the addition of a Police Siren.I am sure it is very suitable for Fire and Police Trucks but not for Crane Trucks.

Works great for the crane and kids are in love with the siren and lights!

Our grandson love lights and sounds so much on his cars and trucks. This module makes a regular car or truck have lights and sounds, that it didn't come with originally. He loves the lights and sounds, and he plays with the toy we put it on more. Great product. Great company.

It may sound a little silly, but for a few minutes, I couldn't figure out how to install this thing on the a Bruder cement mixer. You will notice on the cab of a Bruder truck a black rectangular piece of plastic. Just push from the inside for it to easily pop out. Put the light and sound machine module in its place---it clicks in easily.Amazing addition to my nephews play. Haven't tried to change the lights from blue to orange. Great accessory!

i got this to go on the bruder tow truck, but it also fits on the crane... my son of course loves the sounds and lights, and couldnt believe the trucks didnt come with them. he is disappointed i only bought one, so his other truck is mute. its noisy but thats the point. he loves it.
