Following up on this thread, I got the Diode Dynamics SL1 low beams in the mail yesterday, as well as the Morimoto LED fog lamp assemblies.
Installation for all four lights was less than 30 minutes. No flicker. No splicing, just pulled the fiber wheel liner back after removing the screws.
The DD are made in the USA and have a 3 year warranty and are designed to go into the reflector style housing. They're not cheap compared to the others out there but after a lot of looking around, they seemed to be the best.
The morimotos I had in the super duty already and had a good experience with them, so I hopped on these when there was a sale.
I'll go aim them this evening.
Excuse the dirty trucks.
