Audi A3 bulb replacement

[Kofita]

The other day one of my stock bulbs burnt out. Was looking at them in halfords and they're around 15£

I have a 2007 Audi a3 1.9tdi. and i have found these on eBay, alot better value and they seem to have the xenon light feel i would love.

However i think that 100w is way above the 65 standard that is normally supplied?

Just need to know more about whether this would be possible? has anyone done it? any problems? 

Here is a link to the bulbs: http://www.ebay.co.uk/itm/4-x-H7-100W-SUPER-WHITE-XENON-UPGRADE-HEADLIGHT-BULBS-SET-499-12V-FULL-DIPPED-A/281070655346?_trkparms=aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D20160908105057%26meid%3Da8101fbcbace4fd9bc62e9a8c13281a3%26pid%3D100675%26rk%3D2%26rkt%3D15%26mehot%3Dpp%26sd%3D262698703786&_trksid=p2481888.c100675.m4236&_trkparms=pageci%3Afd6c4386-ddd6-11e7-92b8-74dbd1800093%7Cparentrq%3A41a96ae61600ab6b36d63221fff61733%7Ciid%3A1
