They all have some degree of glare into the cab due to where the lights are sited. Some are worse than others. the more shallow raked the windscreen the worse the problem.Defender and D2 are better as their screens are quite steep bringing the lights further forwards. They have a different area of glare which comes from the bonnet, which you cannot see on the rest of the range, hence on Camels, the top raised section of the bonnet was painted matt black.
