Signs 'pop' because they are very effectively retro-reflective (https://en.wikipedia.org/wiki/Retroreflector https://en.wikipedia.org/wiki/Retroreflector). The brighter headlights with a wider beam would be casting a moderate amount of light on the sign, which causes it to light up brightly in contrast with the surroundings.
The ones in the UK can be so effective that sometimes I have to switch off my full beams so I don't get blinded by the signs (and I'm not driving a new car with fancy headlights).

- magduf 7y agoThe cool thing about smart headlights is that they don't have to dim on the nearside of the car when there's oncoming traffic, so you get more brightness on the side of the road. Regular headlights have to dim both lights equally.
