You can get it from the back. Unscrew the big round cover, and then unclip the wire clip thing that holds the globe in. On the driver's side the battery needs to be moved a bit to gain access.
i did this yesterday. unfortunately it was the drivers side, so needed the battery removed.
easiest way i've found to do it is hold the bulb firm in its place with one hand, and wiggle the electric plug off it .... its easier to handle when its not plugged in.
