Change out Headlight Bulb

I changed the drivers side bulb. The battery is in the way. There is a round plastic retaining fitting behind the bulb that needs to be rotated counterclockwise. This can be reached with adjustable jaw pliers. At this point the plug, bulb and retaining fitting can be pulled out of the headlamp. I reached in between the battery and the back of the headlamp. I have large hands and it wasn't that bad. Unclip the old bulb. Plug in the new one and reinstall. Hope this helps.
