## Description

International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions.

Review: Expensive but seems quality - Took a long time to arrive but I believe it had to come from the USA. Not installed yet but have tested and works fine. A simple kit but one which does what I need. Will be a simple installation. My classic Rover’s horns are weak due to no relays and relying on current passing through the 45 year old horn switch. This kit should solve that, providing for power directly to the horns via the relay.
Review: These worked great with the Hella Sharptone horns on my Toyota. Many comments here complain that the negative battery wire is a bit short but you only need to ground it to any bare metal on the chassis. Shipping only took a couple days too!

### ⭐⭐⭐⭐⭐ Review
*by A***4 on 24 August 2025*

Worked fine. MUCH faster and easier than building my own. Seems like pretty good quality and there was plenty of wire available to run it where I needed, possibly even too much. I may get in there and clean that up sometime.
