All the aftermarket brands (TYC, DEPO, etc) are ok quality but not quite up to Bosch/Hella fit & finish. The external appearance and light output is fine, though. If you want the Euro "look" along with good light output, these are great. The eBay price is very low now, these are usually $200-$300 items.
If you just want to see better at night, get the Hella or Cibie replacement 7-inch round E-code H4 lights. They much cheaper (~$75/pair new with shipping) and the light output is fantastic, same as the full Euro light assembly. I have the Hellas on my W123 and they rock. Best price is at Susquhanna Motorsports:

On my 124's I have Hella 500E Euro lights. For the best prices on real Hella lights, contact PUMA (800-35-HELLA).
