What are best upgrades to existing 4.6 headlights?

[bcredliner]

Yes, this is another tread on upgrading headlights.

I have read many posts on upgrading X5 headlights. Many talk about Depo replacements and others speak of opening the existing headlights and upgrading them. There are lots of different variations. I am looking for one complete recommendation of best specific things remove and products items to add. I don't care much about greater output, I am after an up to date look.

I would like to know if/how the upgrades were tested before sealing up the headlights.

I am clear on the opening the headlight options.

I am not clear on what should be used to seal the headlights so they can be opened again if necessary.

I have purchased the recommended angel eyes.

I have a 2002 4.6 with a 2/02 build date.

Thanks in advance,
