I don’t recall exactly which bulbs but there is at least once case where the filaments do line up and the bulbs fits with minimal snipping of plastic. If the vehicle has a bulb shield it can be a decent mod. If it doesn’t, it will puke uncontrolled light and that becomes counterproductive. if you identify your bulb type you can find more info. Note, high bulbs typically have a much shorter operating life. Also consider an HIR swap if you can. Basically the same thing.
one other note. If you have long life low beam bulbs, switch them out for non long life. LL bulbs run a thicker, and cooler filament. In some housings, this puts some of the light source outside the focal point of the housings, resulting in some of the light not going where it’s needed. Using a standard, basic, cheap, non long life bulb can be an improvement in this case as more light gets on the road.
