Hi Salar
You are quite right, the standard bulbs are not the greatest (the new Captur models might be better, but I always found my 2014 model headlights a bit weak).
This has been discussed several times on the forum. Try searching "bulb" or "bulb upgrade" in the search box. One useful thread is this one I started a couple of years ago regarding "Phillips Extreme Vision" bulbs

Hope that helps
