Dear Adnan,
Is the visibility really an issue or you would like the lights to be brighter for personal satisfaction?
If the visibility is an issue, you can share pictures of what you see during night time with low beam and high beam. This will help us to understand the issue better and we might to be able to help you.
If the issue is only personal choice of having brighter light, that's something we need to understand why do you feel you need to have brighter/stronger headlights.
Looking forward to hearing from you.
