I semi made that once. Had a 100w led chil that i placed on a cpu cooler. With a dc voltage upscaler. So i used the 12v in my car with a lightswitch to turn it on as it was behind my back window.
It did work when people deove with highbeams behind me.
Later i made it portable with an electric drill battery before burning out the LED
If someone drives behind me with their high beams I just slow down a bit and force them to pass. Then I go back to my regular speed only losing a few seconds of time at the lower speed. Works like 90% of the time. The issue is so many new cars have ridiculously bright normal lights that I see their headlights brighter than my own when they're way behind me even. There needs to be more guidance/rules on headlight design in my opinion.
