I've run the standard Hella 7" H4 conversions in two cars. Excellent light, great low-beam cutoff/control and the highs are great.
I'd go with the Super 7 if I was buying today. Choose a bulb to suit your taste. Standard is in the 55watt range.
These look very traditional if that's important to you and generally a bunch less expensive than the LEDs. A drop-in replacement w/o concern over wiring if you stay in the 55watt range.
