I'm trying to set up a wireless system to trigger my motorcycle horn using a push button. The key requirements are that the horn should respond instantly when the button is pressed and continue sounding as long as the button is held down. I've attempted using a pre-made wireless horn designed for bikes, but it didn't meet my needs since it was either delayed or too short in duration, which isn't effective while riding at higher speeds. Any advice on how to build this would be greatly appreciated!

You're right to focus on reliability! A wired setup is generally much safer for something like this. Wireless solutions can fail, and you don’t want that at high speeds. Just run a wire to the button and keep the rest out of sight. It’ll give you peace of mind knowing the horn will work every time without delay.
For your project, consider an analog RF module. They tend to have less latency compared to digital ones, which need time to set up. Just a heads up, though: fitting everything into a compact button design might be tough, especially when trying to keep it waterproof. If you really want wireless, just keep in mind that battery life is crucial—could be worth looking into making it rechargeable.
I totally understand your concerns about reliability while riding at speed. Honestly, if it’s a safety feature, I’d recommend going for a wired connection. It's way less prone to issues. You can run a thinner wire to keep things neat, plus maybe use a relay to make it less bulky. That way, you get a solid, consistent connection without worrying about battery life or lag.
