07 YBR Headlight

Now, this is likely to be a very noob question, but i am a tad confused.

I want to get a brighter light for my 07 ybr, so have been looking into the options

Everywhere I look i have managed to work out that the headlight for the bike is a H4. http://www.autobulbsdirect.co.uk/yamaha-ybr-125--2007-07

So i went along to halfords and purchased one of these. http://www.halfords.com/motoring/bulbs-wiper-blades-batteries/bulbs/halfords-extreme-brilliance-hbu472eb-h4-car-bulb-x-1

However, When i came to replacing the bulb, it had a very different fitting: http://www.halfords.com/motoring/motorcycling/motorcycle-parts/halfords-bike-it-motorcycle-bulb-hmb395-12v-35-35w

With this in mind, what options do I have in terms of a brighter bulbs.

Thank you all in advance.
