A member of the Miata.net forum with the nickname Jumperthumper created another pure cosmetic modification which gained some interest from the Miata community. I decided to check how it would look on my car, to maybe make some sort of kit for easy installation for other people.A Red LED strip can be attached to the trunk lid that will produce a glowing reflection, which looks very nice at night. I found on Amazon a LED strip with 120 LEDs/m which has 3M backing tape. This strip is more expensive, but the adhesive side is more strong than most of the low cost strips.
The trunk lid has several holes with rubber plugs, which makes wire routing more concealed. The original wire leads from the LED strip were replaced with black cable; 1m long with 2 pin connector at the end.
I already had a rear light harness designed for other projects, so I just added a 2 pin connector to the Parking light wires, for Plug-n-Play installation. (this harness now available from my store)
The whole setup took 15 min to install (not counting time for soldering wires). The light comes on when the running/parking lights are on.
