Marvellous, ta!

Got a link, @Nonimouse?

Ta, I have my moments, rarely, but I do.

Going a bit wild here... Cheap double-din car radio, e.g.: https://www.ebay.co.uk/itm/7-LCD-Car-Stereo-Double-Din-Full-Touch-Screen-Radio-Audio-MP5-Player-FM-USB-AUX/373062679428?hash=item56dc44bb84:g:0AEAAOSwiOxeyOQD Gets you FM radio for when you want it, and any content off your phone or SD card when you don't, hands free calling so you can answer the phone when your hands are covered in schmoo, 4x45W output, a remote control, RCA out if you want to connect to an external amp. Some cheap speakers, fitted into your walls (true infinite baffle, almost...): https://www.ebay.co.uk/itm/NEW-Cheap-Budget-700-Watt-6-x-9-Inch-Car-speakers-4-Way-pair-350-Watt-Each/142354731945?epid=7019561990&hash=item212500d3a9%3Ag%3AYEEAAOSwSypY95C8&LH_ItemCondition=1000 Combine with an old PC PSU for the 12V supply and you are away. Stereo was the first one I came across, there are likely better ones out there.

Yep, agreed, get yourself some new bolts on order.

Yeah, with any potentially damp building (i.e. not heated) it eventually gets to it.

I've always found hardboard ends up warping badly, even with lots of nails in it.

Bank holiday tomorrow, Ralph ....

In parallel, yes, that would work, in series, no.

Yep, agreed, but when asking for a regular indicator or reversing lamp bulb, for a car, they are always denoted 382. Using 382 as the search is likely to get you better results for automotive LEDs imho.l, as it will find you equivalents.

This 1000 lumen, which is about the same as a regular headlamp bulb: https://www.amazon.co.uk/CICMOD-lumens-Chipsets-Signal-Reverse/dp/B01LCN5Z0I

382 is the usual code in the UK, e.g. https://www.autobulbsdirect.co.uk/382-p21w-car-bulbs/

Normal bulb or an led with parallel resistor equivalent to a normal bulb.

Nailed it.
