Obviously you are a better electrician than I am.

SuperBright advertises these strips as "Suitable for Automotive Applications." They do not mention adding any other components to the circuit. Silly me -- I took them at their word.

It's not as though the whole strip stopped illuminating -- just random elements here & there. My original installation concealed the leads behind the strip, which looked nice but made replacement difficult (door panel had to be removed, which fortunately I was doing anyway to dye the carpet). I now have the leads configured for replacement without door panel removal.

FWIW: A few elements have stopped illuminating in some of my LED bulbs as well. Manufacturers of those devices do not intend for end users to add components to their circuits either -- they are plug & play replacements for incandescent bulbs.
