Euro Lights are anywhere from $250 (used off of grey market cars or new import from Asia) to $500 (new, usually with side marker/turn indicators). You also need an inexpensive plug for the Euro lights described in the archives, along with the wiring color codes, references to installation articles in the STAR magazine, modifying your stock wipers to work or what Euro wipers to buy (expensive). Detailed installation instructions are there as well. Try a search on Euro lights, Headlight wiring, Euro wipers, etc. - dozens of threads and tips.
