Does anyone make LED backup bulbs for an E90 LCI?

Yup! Here's the current situation:
RELIABLE, TESTED OPTIONS:
1. 9-LED AutoLumination 194 Canbus bulb (I have this on my car): light fills the housing, decently bright at night. For $11/pop, I'm satisfied.
2. 5W Cree LEDs: [purchase here: http://cgi.ebay.com/ebaymotors/BMW-E...ht_4770wt_1024 ]:These are quite bright, CREE makes great LEDs, so you can be assured that these will be bright. I would be upgrading to these if...
3. LUX (the angel eyes guy) and HPB (interior LED lighting people) are both working on LED reverse bulbs. I can't wait to see the results of them, I'm gonna guesstimate that by the end of the month we will know a lot more about their products.

CURRENTLY UNTESTED:
1. an ebay seller is claiming to sell a 68-SMD LED t10 base canbus bulb (aka a backup bulb for the e90 LCI). I emailed the guy just to make sure that it is really a canbus bulb, and I'll update this when he gets back to me.
2. AutoLumination sells a 7440 replacement bulb that is a, get this...10 WATT BULB!! (it's called the 10 Watt Eagle Eye Tower) This idea came to me, the dimensions almost certainly would allow it to fit in the reverse housing (snuggly)...so if I can modify the bulb to have a t10 base, then it would be out of this world bright. And I feel like a 10-watt bulb wouldn't cause bulb-check shenanigans--but then again I believe it's looking more for resistance, so I don't know. I emailed AutoLumination asking about the construction of the bulb; and if I could desolder the bulb from the base, and resolder it to a t10 base they sell. We'll see what's up.
