The Bullmobile has an interesting headlight setup. One bolt and two retaining pins and the whole unit comes out. One quick disconnect and the whole unit with both bulbs comes out and you are free to replace the bulbs. I replaced the burnt out headlight with an upgraded one and the blinker bulb with flaking orange with a new one.
The connector to the bulb had some retaining arms to keep the bulb from sliding out but the plastic was so brittle that it snapped off by looking at it closely. If it becomes and issue I promise to use zip ties to repair it.
