The Armytek Prime series fits your description and has a magnetic tailcap. It really needs its optic replaced to perform as advertised though - more on that in this post.
The Zebralight SC64w is a popular higher-end EDC light; Zebralight ships worldwide, and 79 USD looks to be 60 GPB.
For working on cars, you might want to look at a right-angle light that’s usable as a handheld or a headlamp. The Armytek Elf C2 is a nice option there - I’d go for the warm tint myself. It has a very strong magnetic tailcap.
