Where is your light at? If its mounted under the back shelf shinning
into a dark grey trunk It usually is dim.
When the lights were mounted on the trunk lid they shinned down into the
the trunk and typically didn't have a lens over the bulb.
One suggestion would be to see if you can remove the lens and see if
that improves the amount of light in the trunk. You could also mount an
older trunk light assembly from an older car (mercury switch type) and
mount it on the trunklid, but be sure the light goes out when you close
A trim shop could set you up with a lighter colored trunk trim. I hate
the dark colored trunk trim the manufacturers are using now.
