New LED lights on DealExtreme: Compatible/practical with XB-600?

The brake light on the XB600 uses the 1157 dual element bulb, so you probably could replace it with the LED assy. Your energy consumption for the brake light would go from around 30 watts to four. The turn signal bulbs are far smaller. Open the blisters up to check. HOWEVER:

1. how much of a typical ride do you spend with the brakes on? Remember it's watts times time that adds up to energy drain.
2. Remember that your front headlight assy is a dual-bulb 18 W assy, making around 50 watts fr night lighting. This won't change the totl energy cost that much, especially as the hub motor is drawing 900+ Watts at full cry. Even limping home at night, I've generally left the lights burning, as I can save more power by having a light touch on the throttle than I would gain by putting out the lights (especially considering the chance of an emergency room "visit."

The one justification would be to reduce the 12V accessory drain to allow you to change to a more conservative and reliable DC/DC converter. I'm seriously thinking if this, as I've burned two of the stock units up. I'm thinking of one that's used by the Telco's to get 12V accessory power off their 48V standard buss voltage.
