I also put in these globes, they were fantastic, especially the colour, quite white. But my emphasis on the word "were". Cos the left side only lasted 1 week :banghead::banghead::banghead:
So I replaced both with Nightbreakers, must say The Zone globes looked much whiter then the Nightbreakers.
Although the Nightbreakers have a longer throw. Coe when I drive only with my fogs and I switch on my main beam, the main beam and fog shines the same distance.
Therefore, from my observation, the pro of the Nightbreaker is it's range but the con is its colour and vice versa for the The Zone Xenon look bulbs.
