Astra J beam Light problem

[caretaker]

Hi All,
since i bought my Astra j 1.7cdti 2011/12 Elite- 5door Hatchback, i have been reading this forum and other Vauxhall forum to get more information and recently did my own servicing.
 
I noticed another thing on my Astra, as when you have your front fog light on, the beam light wont stay on and when you turn off the fog light off, then the beam light stays on. If the Front Fog lights stays on, you can use the beam to flash, but it will not stay or permanent. Is this how it works.
 
I noticed another thing, is when i drive the car at night, i see lot of refelection of the opposite side of the car light on my windscreen and they are just normal light. I thought something wrong with my screen or i need to have the Anti Glare Glasses.
 
Thanks for looking at the post and appreciated your replies.
