I have found these bulbs and I'm very happy with them:

http://www.aliexpress.com/item/HotSale-2pcs-lot-super-brightness-High-Power-1156-led-30W-CREE-XBD-p21w-led-ba15s-Reverse/2036956876.html

Brighter than the standard bulbs and the color is nice WHITE.

Equipped with genuine CREE XB-D LED chips.

The reflector is illuminated very well so the effect is similar to the standard bulbs.

My Octy3 accepted the bulbs without coding.

The price is reasonable I think.

Bulbs get warm in a few seconds but this is not a problem with reverse lights I think (and the XB-D chips have the same brightness at 85 C degree )
