Does anyone know if it will be possible to replace the standard headlight bulbs with similar LED bulbs? Little bit gutted I didn't manage to get the adaptive LED headlights but this seems like the next best thing!

5AK: Adaptive LED Headlights - £710
Featuring daytime driving lights with LED 'U' shaped BMW i design. Adaptive LED headlights improve visibility by following steering angle of the front wheels, giving better illumination of the road ahead through corners. Adaptive Headlights not active when car is reversing or when car is stationary and steering turned to offside, to avoid dazzling oncoming traffic.
Replaces 5A2.
5AK: LED light elements - Standard
Parking light, daytime driving lights in LED technology (14 heigh-power LEDs) with LED 'U' shaped BMW i design.
Not with 5A2 LED headlights with LED light elements.
The only option to change the headlights in the UK price list is 5AK, the adaptive headlights - there's no option to change the bulb type without going adaptive.i3me said:Lets get clear on what "standard" lights are: halogen. The daytime running lights are LED and as an option in Europe the halogen main lights can be upgraded to LED. LED is a factor 5 more economical than halogen (to be exact 16% of the power needed to provide the same amount of lumen), so 100 Watts Hal. = 16 Watts LED.
I presume you meant Xenon?Atommad said:It will be possible to replace the standard bulbs with a brighter, whiter halogen bulb.
My guess is that to get an LED bulb would require the whole headlamp unit to be replaced and the on board software updating. This is definitely a question for your dealer!
I believe that's the case with the Nissan Leaf too (you can get a spoiler with a solar panel to charge it) - http://www.mynissanleaf.com/viewtopic.php?f=16&t=469ChrisRayner said:I looked at this question when speccing my i3 order. I discussed it with the salesman, and pointed out that LEDs were the way to go for economy of charge use. He rather surprised me by saying that the lights don't work off the main battery pack. He told me there is an ordinary 12v lead acid battery to run them. Seemed a bit odd, but he was insistent. Can't think why, unless there is a problem in down-regulating the traction battery voltage for low volt circuits. I suppose it's just possible that the cost and weight of the gubbins required to do this is greater than bunging in an ordinary car battery, but it doesn't seem very likely. :? :?
Which would indicate there's no 12v battery (and the pictures in that press release seem to confirm that). Seems like the correct decision to me! Probably the same size and weight as another cell on the main battery.The power electronics serve both as an inverter for the power supply from the battery to the electric motor and as a voltage transducer interacting between the high-voltage battery and the 12-volt onboard power system

You mentioned here that the heated seats and heat pump are now standard in Europe, does this mean I will get the cost for 4T9 and ZWT taken off my order?
On the UK price list the heat pump is not listed separately, its listed under "Cold weather cabin preparation" leading me to believe that the heat pump is required for cold weather cabin preparation?
