This one was pretty easy. Added a 48-LED panel to the roof-light and trunk-light. The panels I bought came with 5 in a pack for $10, delivered. The pack contained 3 different kinds of car-bulb adapter for each panel. The one in the ceiling worked just fine but the same adapter in the back didn't fit so I wound up connecting the leads directly to the bulb socket. In the back, I also wound up using 2-sided tape to connect the panel to the *outside* of the light.
