Angel eyes upgrade

I have a 2007 750Li and want to do the angel eye upgrade whats the difference between the mtec bulb and the dtech bulb i see E92 advertising. Especially since on ebay it seems to be a $99.99 vs $179.99 differnce? which performs better and which lasts longer?

also for the interior led is there a package to get all bulbs at once or do you have to purchase them one at a time? where is the best place to purchase them?

I purchased a set of 12 watt Angel Eye LED Bulbs from BMWLED .com, on Ebay. Cost was $69.00 and they are the all aluminum body type. Not the cheap plastic body style. I did the install yesterday and have an album with pictures of the lights during the day and evening. For the price, I'm totally happy. I also purchased two set's, so if your interested, I'll sell the extra set for $65.00, with free shipping. They are new, never removed from box.

Since you did it yourself did you take the bumper off or did it without removing the bumper? Also I read where someone suggested cutting something. Did you do it without havee to cut anything?

Would anyone that knows anything about the angel eyes mind having a peek at my post on the sticky thread?

Ty in advance

I looked at all the different ways of doing the install. Removing the bumper, or un-bolting the headlight assembly, moving it forward 4 inches and trying to get to bulb that way. One person on here suggested cutting part of the bracket blocking the access. I looked at the position of bracket and the thickness of metal and decided to cut the bracket. The bracket is not load bearing and the metal is paper thin. I have restored over 100 cars and am rated as a commercial grade welder. I know metal...
