the one that i bought is from this guy Wireless Car CCD Rear View Camera for BMW 1 3 5 x3 x5 x6 E39 E53 E46 E82 E88 M3 | eBay

i just checked out his lux - it says, less than 0.5...

night picture is crappy...

so, i might get another one, with better rating - thank God, i did not drill anything, so i can experiment with different cameras!!! lol... it is very low on my priority list, to be honest - the camera works, and when i have nothing better to do, i might venture into it again...
