I got my high beam bulbs from Daniel Stern lighting, and they are great. If you search you will find all the info for ordering. No trimming needed. I also have the Slee harness and have not had any problems, yet.
I got the JD for my low beams, and I got some high beam bulbs from Daniel Stern lighting. The high beams are great too, and no trimming required. If you search I'm sure you can find the info for ordering.
