LED Headlights...
Owning an older truck 97 F350 Ford Diesel, back then the only option for headlights was Halogen bulbs and, while they work pretty well and I can see pretty well with them, I wanted to upgrade to a bet...

Mine actually switch between different sets of LEDs. One set for low beams that matches the pattern of regular low beam lights and the high beams are set to the high beam pattern of regular lights.
