Yep - common problem with electronically-dimmed lights, where the small residual current makes an LED glow. The reduced resistance of a bulb would pull the transistor output down to zero, but the LED can't, so it floats slightly above zero volts. It won't really drain your battery.
I'd just change them back to bulbs, personally. The light you get is much 'warmer' and seems like real light. Even though the LEDs are a bright pure blue-white, they're not giving you all the colours that normally make up 'white' light.
That's the problem with LEDs and fluorescents - it's white light, but not as we know it. Effective as a temporary reading light and very effective for instrument lighting etc. but for general room lighting, not really very nice. Some LEDs and the energy-saving fluorescent bulbs you get for your home put out a yellowish 'warm white' but again, it still doesn't have all the colours that you get out of a halogen bulb.
