I recently bought a new car with very bright LED headlights. These were not even modified. I just knew how insanely bright they were by the fact that it lit up the interiors of cars in front of me in ways my last car with normal lights never did.
The problem was the fact that there is a big ass computer monitor in the console of every vehicle, so of course you'd need rape headlights to see anything. Thankfully they let you turn it off, so I keep the monitor off.
My solution was pretty simple, I got my hands on the service manual and figured out which wire in the headlight connector was the normal headlight power, and how much current they drew.
Put a couple power resistors in between to bring down the current by a quarter or so, which cut the light output by almost half. Now they are reasonable! Highbeams are still full power so they are comically bright compared to my lowbeams.
While I did that the computer stuff was spooky to me so I unplugged every antenna from the computer boxes, except the FM/AM of course.
I hope this forces mr glowie to have to leave his comfort in India to mess with my car by hand.
