RLS, I basically did the same thing but first ones like the sticky you used was a warm white and I put in three of them and man what a difference.
Latest acquisition is a pack of ten of these which are bright white. They have 48 5630 chips per panel.

They have adaptors for 1156 bulbs on the older Airstreams. I am thinking of using a tail light lens as initial pattern, tracing it out on lexan and then reducing it about 3/8" on all sides so it will allow a deeper set into the light recess. Might have to reduce it more but once I figure out the size I have a pattern for the rest of them.
I figure I can mount them with dabs of a roof sealant I have found called Through the Roof which has a very wide temp range for service and application and also clear to hold the lexan in place. It can be cut free and replaced should the need arise. Not everyone sells it but hit the website and it lists dealers nationwide. Here is their tech data sheet:
Even more interesting is this stuff will stick to EPDM rubber roof material and most adhesives won't. I found this out when I called Weldwood and talked to tech section and they said their contact cement will not adhere to it.
Two of these should mount on the lexan and give 96 LED brake lights. I will solder the + and - wires together between the connector on two of the lights so all 96 lights work on same 1156 plug adaptor. But then again I will probably try one 48 LED panel and replace the lens and get back and look at it in the dark and daylight and see how they look.
On all 1156 and two prong plugs I will apply the protective goop (can't remember the name of it) that prevent contact corrosion. It comes in small tubes from the truck part supply places.
To enhance the overhead interior lights I am going to put a string of twelve of these on the outer edge with four across the sides and wire them into circuit. That will give six 18 chip in the sockets and 36 more on the outside.

For the tail lights I am thinking five of the above stuck on lexan and using one of the 1156 adaptors from the above lights and plug into the issue recepticle. If six will fit in even better.
As Andy says you can't beat LEDs and this was brought home to me very clearly as we worked a wreck scene out on a dark rural road late one night. I was working traffic control on one end and the husband of one of the drivers arrived to pick up his wife driving a late model Cadillac which has a massive LED light system on the back. I was 50 yards back from the impact scene so I could see every red light we had going and the light intensity of the Caddy was just as effective as our roof strobes. I knew right then how I wanted the AS to appear but at that time I was not into LEDs.
Now that I have a much better working knowledge of what is available and what to buy and what to pass on I hope to be in a much more visible position when we hit the road in a few months.
Bottom line is there are apparently three levels of LED, one in the 3000 range, ones that are called 5050s and the others are 5630 which are brighter. Thusly all I am laying in are the 5050s and 5630s.
I read a recommendation recommending no more than 300 individual LEDs per circuit and they come factory wired with 23AWG wire. The wire I am soldering to them will be 18AWG for the longer runs.
