If you're at eye level where you're getting hit in the face with the brightest part of automobile headlights, I think you're just plain going to have a problem.

The Busch&Muller Big Bang is apparently literally a motorcycle headlight that's adapted to be powered by a battery and put on a bike.

But you're just straight up going to have huge issues getting a bright enough light to overcome an automobile light in the face. Unfortunately, my best suggestion would be to buy a bike that's more upright than your trike, so that your head is above the cutoff of the beam - where it will be *much* easier to see. Either that or find places to ride that don't have traffic on them.

Other than the above Big Bang light, I don't know of any other high powered bike lights with a cutoff. Anything that's actually as bright as an automobile headlight is going to cause you to start really ticking off oncoming traffic - like driving your car with your high beams on all the time. Lights like the NiteRider PRO 3600 are very expensive, and have short runtimes, but will put out as much light as 2 automobile headlights. But...I wouldn't want to be pointedly pissing off all oncoming traffic.

Headlight beams - when they're on low - look something like this -


As you mentioned, if your bike is low enough to put your head in the main part of the beam, you're really going to have trouble. If you can get a bike that puts your head above the main part of the beam it's a lot easier (though still not easy).
