I use a Rockbros 2-in-1 rechargeable horn and light that I got from aliexpress. It makes an earsplitting beep when I push the button. This ensures that when a car crushes me under their tires, they will be momentarily confused as to why they hear a smoke detector going off in the second or two before I die.

I use front and rear lights from MECs (Mountain Equipment Co-Op in Canada, similar to REI) in-store brand. They’re not super bright, but they’re bright enough so I can see where I’m going in random dark spots and generally be visible at night.

These ones. Though it doesn’t look like the rear (red) lights are available any more.

Cygolite metro and some tiny knogs. Really like the set up.

Every fancy light I’ve ever had — and I’ve had many — either stopped working / charging, got stolen, or has been lost.

Took me a long time to realize the actual best lights are cheap and run on replaceable AA batteries.

I personally like to use really really bright LED lights pointed straight into the eyes of oncoming traffic.

Occasionally an oncoming car will take a swipe, or a cyclist will stop and punch me, but it’s well worth it for the widespread misery I can effortlessly cause.

It also makes it quite hard to see anything that isn’t in my ‘cone of death’, which is good in the same way that peril-sensitive sunglasses are!
