The Germans seem to have a standard (with TUV certification) for it, as of course they do. But we don't get much of that kit here.

(And because search engines are absolutely ruined: Searching for less, like "dim bike light" or "non-blinding" or whatever always winds up with finding more, instead.

"Oh, you're searching for a nice pleasant light that just illuminates the path in front of you at a warm color temperature without blinding anyone? Let me show you the MEGAFUCKER 9000! Powered by 48VDC and over 9000K, this light is guaranteed appear brighter than the sun and to ABSOLUTELY FUCK anyone within a kilometer! /r/fuckcars approved! You always knew you were an asshole, and with the MEGAFUCKER 9000 everyone else will know it too!"

Every single time.

(It's the same with anything else. Want a small, diminutive spatula so a small egg pan can actually be used for cooking instead of wall art? The more specific the search terms are, the bigger the fucking spatulas in the search results become.

Or even industrial or craft materials. Want rigid, open-cell, large-pore foam that doesn't sponge up water for a project? Good luck. Unless you already know exactly what product you need down to the SKU (which one can only glean via telepathy), the search results will consist entirely of opposite-world SUPER-SOFT EXTRA ABSORBENT foam.)
