If just the the blue part is sticking out and the rest is wiring. You can go in with a Dremel and shave down the blue housing that is sticking out. You would have to remove the camera to do it. Then once flush with the wall you can reinstall the camera and see if caulking is needed on the outer edges.

A typical motorcycle head lamp bulb (H4) is less that 22mm in diameter (the bulb and socket bit), an e12 bulb can be found that is less than 22mm in diameter ( https://www.amazon.com/Candelabra-Incandescent-Replacement-Chandeliers-Refrigerator/dp/B08T17Y4GM/ref=sr_1_9?c=ts&keywords=LED+Bulbs&qid=1676312505&s=hi&sr=1-9&ts_id=2314207011) then just buy a cheap light and take it to bits and fit in your bike.

Do your best, caulk the rest.

Caulk

There may be a small adjustment screw attached to the mixer cap that prevents the shower handle from turning a fraction of an inch. That small adjustment may get you where you need to be by allowing you to turn another 1/4 to 1/2 inch more.

I’d look for an injection of cortisone!! J/k it’s all good.

Just put a battery charger, or remove the battery and put a 12v power supply

Thank you so much! The reason I’m looking to change the shower cartridge is because my shower water doesn’t get very hot anymore. It’s only warm at best. Changing the shower cartridge should be the right way to fix that issue right?

Buy this. I have used it to make a lamp using a 12v led car bulb. adapter

The bike may be 6V. I don't know British bikes, but I would double-check.

The headlight is also probably sealed beam as well... as a giant light bulb. Most suggestions here will not work.

I would buy a new cheapo headlight off ebay that takes a separate bulb. Then use any bulb and dimmer you see fit.

I would be tempted to get it running. If nothing else, I'm sure putting around a parking lot with it would be fun.

If it were me, I'd be awfully tempted to restore it and ride.

Definitely the easiest.

cartridge

Turn off the main water supply. Disassemble the body. Remove faulty cartridge. Go to home Depot. Buy new cartridge. Install.

Thank you for clarifying! I really appreciate all your help 🙏

*varistor, which is short for varying resistor, a component for which its resistance changes with the applied voltage, meaning it doesnt have a set ohm rating. A potentiometer isnt a varistor, and a varistor wouldnt be a very good dimmer, considering its ability to affect current is dependent on the voltage being applied to it, meaning to use it to dim anything, youd need to be able to dynamically reduce the applied voltage, meaning youd need a dimmer for a varistor to work as a dimmer. Also, the dimmers im talking about are made for AC current, they switch said AC current on/off at an adjustable time after the start of each half cycle, thus modulating the width of the pulses of current sent through the circuit, like i said, a version of pulse width modulation. You ever seen a dimmer switch in a house? Most likely a solid state dimmer.

You could pretty easily do something with LED strip lites inside the headlight housing. You can buy one with “smart” features so you can control it from your phone.

If it's not going to be driven, I'd open up the headlight fitting and remove the existing lamp and lamp holder, do it carefully so they can be replaced.

Replace these with a modern, dimmable, DC powered lamp, ideally one that can be controlled with a smart device.

Compatibility is a complicated issue. Their toners are based on a precat lacquer AFAIK. They should be alright on a fully cured stain or finish, but you can always ask the manufacturer, being sure to specify what you've used. A coat of shellac will often solve compatibility issues. As for top coating, they sell rattle can pre cat lacquer that you should use, in the sheen of your choice.

Use the battery in the bike. Put the battery on a trickle charger.

You're thinking of a rheostat, and those are very outdated for the purpose of dimming lights. Theyre big, inefficient, and get crazy hot. Nowadays most every dimmer youll find, especially in residential electrical, are gonna be solid state dimmers, which use variations on pulse width modulation.
