Installed the Bosch Euro headlights on Saturday; some info for you:

1) Bought them from Blaufergnugen ($430 w/ Euro parking/turn light units). Good price, but some problems
a) No bulbs; called Blau on Friday when I noticed; they're back-ordered on some. I transfered bulbs from stock lights.
b) Left turn signal unit is a Valeo (right was Bosch). Blau getting another call Monday (I paid for Bosch; that's what I want). Held side-by-side, Valeos appear cheaper than the Bosch units.

2) US wiring harness definitely does NOT have any provisions for city light wiring. The hole in the connector is there, but no wiring at all. I actually pulled back the rubber boot and disassembled the two-piece connector to see how I could hook up wiring (royal pain; broke a snap fitting on it, but all went back together and all seems to work OK). Figured that would need a female butt-style connnector to fit in city light contact hole and hope that I could get a connector that would work from Radio S**t. Well, when all the power leads popped out of the connector, and I spent some time with a DVM figuring out which wire does what, then seeing the only way to get city light power would be tapping into the parking light wire at a location that probably gets some road crud thrown on it, I gave up. So, no city lights.

3) Installation once I forgot the city light wire was a snap. Parking lights popped out as described in owner's manual, headlights held in by 3 T30 Torx bolts. As others in archives noticed, side bolt could be difficult, but I had a small ratchet wrench that takes the little hex drive screw fittings (my T30 socket fits it; wrench is $5 at Sears); was a snap.

4) performance: Good & bad
Good: low beam broad and flat, better range than OEs. Hi beam like a spotlight.
Bad: The cutoffs much sharper with Euros, esp. upper horizontal cutoff on low beams. Fine on level roads, kind of a pain on hilly Steelertown terrain as you approach the bottom of a hill and can't see ANYTHING on subsequent level or uphill section. Also, low and high beam co-alignment not the greatest. For good lows, high aimed higher than I want. For best highs, lows aimed too low. Too bad they don't have individual hi/lo beam adjustment like old dual H1s on old 911.

Ray,

I agree with you about the basic install. It took me about 10 minutes to put them in and that made me confident that the city light wiring job would also be quick (hah-hah-hah). Well, after a couple of hours sweating and cursing in my garage, I was able to neatly thread wires through the rubber boots on the multi-pin connectors (having tapped the parking lamp ckts, as you mention) and used gold-plated connectors from a Neutrik XLR (pro audio) plug to slide onto the correct pins. I know some folks here have just cut the parking light wires to 'have that Euro look,' but I happen to think that the parking lamps provide useful extra marking for the car (and I don't happen to live on a typical, narrow 12th century lane where parking 'half up and half down' would make separate parking lamps useful even if I could rewire the car that way ;o)

As to the aiming, I suggest that you experiment a bit, using the basic E-code aiming principles as your guide. I live in a rather hilly part of New York, and I was able to adjust the lamps so that I found the ideal balance for dipped and main beams. I also added Jahn bulbs, which seem to provide 'whiter' light than the stock ones.
I've always put E-code lamps into cars that I've had over the years, and I still believe the difference is night and day.
