Can't believe I'm asking this but I'm a little confused 
One of my headlights seemed like the light was pointing down a bit. On closer inspection I see the H7 bulb didn't look like it was fitted right. So I took it out and it sat better once the bulb was turned 180 degrees. I plugged it back in, tested it and it blew so it must of been the right way before but it don't sit in right I played with the other bulb and it too blew
Stupid me anyway brought new bulbs but I'm worried which way they do go and if the plugs will be plugged right. I have googled to save myself the shame but couldn't find much though I read that H7's it doesn't matter what way round the terminals are? i.e. positive and negative?
If someone can check to see if the brown wire is the top or the red and what way these bulbs fit, like the lip bit is it top or bottom on bulb I really would appreciate it
I got a MK1 Leon Cupra 53 plate.
