LEDs on the golf I recently purchased seem to mask the oncoming car, or car I’m following from the lights. So effectively there’s a shadow exactly where the other vehicles are. Been using them for a week or so every night and they seem to react quickly (not sure if the golf uses it’s radar combined with its camera), but I’ve had no angry flashing coming my way. It’s fascinating to watch the shadow track whatever is in front of you. Switches off automatically if there’s lots of road signs, lower speeds or junctions. The main beam and dipped LEDs are astonishingly good coming from xenon’s on my other motors. I can understand the above rant as the main beams would be dazzle anyone.
