How do I change the cargo light on my Honda

You have to go up from under/behind the bumper to get to the bulb.

inside the rear cargo are are 2 pop out access flaps, remove them and peer inside. The Tail light guts are visible. Bolts to remove the entire assembly, or get some small hands to twist out the offending bulb sockets. Careful, body acces hoes have sharp edges.

it could be just a bad earth on that side give all the earths a good cleaning up and then try it again,,,

YOU MUST REMOVE THE INSIDE PANEL TO GET TO THE LIGHTS

1. Remove the fog light mounting screw.
2. Disconnect the connector from the fog light.
3. Turn the socket about 45° counterclockwise and remove it from the housing.
4. Remove the bulb from the socket.

To Install:

1. Install the bulb in the socket without touching the glass with bare hands.
2. Turn the socket about 45° clockwise to install it.
3. Connect the connector to the fog light.
4. Install the fog light mounting screw.

The lense should unscrew from the outside , some bulbs are push and turn and some are wedge base which just pull out.
push and turn bulbs have a metal base but the wedge base are all glass.
I changed a high stop bulb on a 2001 odyssey in this manner.

make sure u have put the right bulbs in. rear brake lamps are dual filament....

I believe that light is accessed through the inside of the trunk.Remove the carpet from the back of the light housing & you will most likely find a bunch of plastic wing nuts that hold the taillight assembly on,remove them & push the housing out carefully,then the light bulb just twists out.

You can change this bulb by gaining access throught the hatch back. I hope this helps you.

Yes, the clock back light can be changed but unfortunately you have to remove the entire instrument cluster to do it. This can be done yourself. First order the clock light bulb from Honda (not expensive). Then get a Haynes Repair manual from an auto parts store (<$20) and a trim panel removal tool. Follow the procedures for removing the instrument cluster trim panels in chapters 11 and 12. Take your time and be patient with the panels to avoid breaking off attachment hooks and clips. The most difficult part of the job is getting the steering column trim covers off.
