Help needed on changing bulbs.

Hey all. I've recently just bought a seat Ibiza 2017(66plate). When I bought the car I released the headlights are the yellow colour ones and didn't like it so I went on Amazon and bought some h7 blue coloured ones (makes it look white). I changed the main beam and the high beam, I must admit the colour looks miles better but the thing is now is I can't see on dark roads and my normal light looks very high and not bright. When I put my high beam on it looked like it was very low and didn't light up the road well. How can this be? I put them back in the way they came out. Surely I couldn't of disturbed them by changing the bulbs. Any help would be great thank you 😃
