Hi All, 2nd post here!
I ordered the EFX AngelEyes off eBay and just installed them last week. Below is my day shot of it.
Short Story:
Yes, you cannot see the LED Angel Eyes during the day. It's almost non-exsistent. Yes, I would like it to be brighter (and yes, I did install with the LEDs facing left-right vs. up-down).
Long Story:
I did not like the yellow of the halogen during the day as well as the look of the halogen and xenon during the night. I've never really cared about daytime running lights in the first place, so the fact that you cannot see the LEDs during the day doesn't really bother me. But if there comes a brighter LED, then I will most definitely upgrade. The EFX was very easy to install. No errors and came in a nice box and I received them quickly. There was no instructions, but it was self-evident. There was an adapter/heatsink combo piece that basically looked like a 1"x1"x3" rectangular block with one end connecting to the LED and the other to the BMW light wire. There was a space towards the outside of where the LED is located and I used double-sided tape to secure it to the metal surface there. I will check on it on occasion to make sure it's still secure, but not a big deal as I know double-sided tape on hot metal will not last forever. The space where the LED is located is tight. My hands/fingers were not large enough but luckily I know a girl that's a grease monkey and she did it for me. Overall, <2 minutes to figure out how to open the LED cover on the X5 and remove the halogen, ~5 minutes to figure out where to put the rectangular adapter, ~10 minutes to find the tape, ~5 minutes to install the LEDs and get push the wiring in.
Picture was taken with the sun behind my back. I was kneeling about 3 feet away from the front and it was approx. 2pm.
Another pic of the LED head on taken in the same manner as above.
And yes, in the night they do look like the advertised pictures you see all over. I can post those pics if you're interested, but it looks like what you see on the web.
Hope this helps others make their decisions. I'm perfectly content with this setup until they make a brighter light.
