Feedback on basic main beam/horn wiring diagram requested

[DarkerSide]

Hi folks

Loving my TSDZ2 conversion, and looking to add in some additional electrics:

• Main beam headlight (dipped headlight/DRL already provided by a dynamo-powered light), so I can retire the Exposure Strada on the handlebars
• Horn, so I can retire the Mk1 Lungs.

I appreciate this is about as simple an ebike lighting circuit as one can get, but feedback on the attached to ensure I haven't forgotten something warmly appreciated. Key thought is: should I be activating things through relays, or can I just go direct from the switch? (PS my ability to make pretty-looking diagrams in visio far outweighs my electrical knowledge - I am an utter novice at this.)

Planned major parts: https://www.amazon.co.uk/hz/wishlist/ls/3M5T5GYG474HX?ref_=wl_share

Picture of bike for showing-off purposes...:

You don't need to convert to 12v - look up horn

also I used these as daylight running lights

You can also get your main beam running off the bike battery without a convertor.

The buck converter isn't needed you can by stvzo lights with internal step down voltage and integral horn they then simply run off the battery via a switch, the the Tongsheng uses a splitter light /gear change sensor splitter cable whether this can power the lights enough I don't know.
