I dunno if it's just alignment, but it seems that one headlight is brighter than the other one. At the floor, the beam of one of the headlights seems to be 'wider' than the other beam. Is it a simple alignment? When I look in front each of the headlghts, both seem to light the same though

It's very easy to not quite fit the bulb in its socket properly, seeing as it's such a barsteward to get at. Try checking to see if the bulbs are properly seated in the holes.

The off side (think that is passenger side) will have a bigger spread to illuminate the side of the road etc, the drivers side one won't, so it doesnt dazzle other drivers. That's why when you go to france etc you have to use those funny light blocking sticker things

funnily enough it's the driver's side which seem to be more spread.. (here in malta, driver side is on the right hand side)

on the right here too, my lights are the same, ones higher and more spread out while the drivers side one is down slightly and less wide spread
