## Description

Review: Easily the loudest in the class - For the price (Rs. 960 when I bought and now is a little lower) this looks good and the quality feels good as well. After fitment, it is significantly louder than my older horn (Roots Windtone) and more pleasant. Roots corroded easily and sounds meak everytime I had a water wash. Even though water is not sprayed anywhere near the horn. This one had no such issues. The description says water spray proof, but they'll definitely corrode and doesn't sound good when sprayed on with water. Be mindful of that and you'll be good to go. Very good highway performance and dare I say, a little bit too loud in the city env. But that's a necessity in the current traffic scenarios. You can't go wrong with these Bosch Scarlets. Go for it. They're great.
Review: Excellent Product under legal boundaries - Great sound, Quality, looks, tone and overall performance of the product. Instead of relay I made a ground wire connector with clips shown in the picture above (For better sound and performance) because Honda Amaze only have one connector per horn.
