I would say just concentrate now on finding some headlight bulbs that match and stop there. The money spent on bulbs could go on another mod...trust me...spent a fortune on my old Ibiza trying get sidelights/headlights right. Try not to sacrifice performance too much for the sake of styling. In my experience, the whiter/blue the bulb, the crapper the visability. Why I went in the end for the Philips Power2night GT150 bulbs. Good balance of performance and styling (blue tip to create subtle blue tint in reflection of headlight).
