2003 Honda Odyssey Brake light replacement

Open the rear hatch. Between the tail light housing and the rear hatch opening there is a trim strip with two flush fitted flap doors. Insert a small straight blade screwdriver into the small slot on the tail light side of the flap. Pry gently inboard and the small flap will open (the hinge side of the flap is on the side of the rear hatch opening.) Now you can remove the screws that hold the tail lamp assembly in place. Finally, there is still a "spear point" clip that fits into a socket near the front outboard corner of the assembly. Gently pry with a tape wrapped screwdriver (avoids scratches) and force the assembly straight back. The clip should release and free the assembly so you can change the bulb(s).
