Driving today in the bad weather I observed a number of drivers today not using dipped headlights.
The problem occurs when the heavy rain mixed with spray like today, reduces visability & you can't see the tailights in front of you. When I got passed the cars the vast majority relied on LED lights & nothing else, great if they are behind you.
Those LED car lights should be used inconjunction with the rear lights. Most modern cars have a seperate Brake light so I don't see why not
