There's some debate on whether Bosch or Hella is better. Then Depo then TYC. I haven't heard of any functional problems, just comments on build quality. All depends on what you want to spend and how hard you want to work. You can get used OE on eBay for the price of Depo or TYC but you have to deal with eBay.

Depo and TYC sets usually come with clear corners. It's a matter of taste. I believe DOT requires an amber reflector in the front corner visible from the side. The lens can be clear but the light should burn amber. Something like that.

Blank valence panels are $12-13 retail from MB. DOT wipers don't fit properly or look right over Euro headlights, IMO, but they serve the function. A set of Euro wipers will probably cost you more than you'll pay for Euro headlights. Euro valences have wiper holes in different location than US valences.

The are wiring guides in the archives. You have to have the 4-pin connectors (might come with Depo and TYC sets), then pop open the old connectors and move pins around. No soldering or crimping unless you want to activate the city lights.

There's the option to have vacuum headlight vertical adjustment. OE will have mechanisms for sure. Depo might, TYC doesn't come equipped but might be able to retrofit. You'll also need a Euro headlight switch panel with a headlight adjustment thumbwheel.

Euro headlight fitment on a US SDL is tight. You might have to trim the airflow meter slightly for clearance. The headlight or the airflow meter has to come off to change bulbs.
