LED dome light upgrade won't stay in place
I purchase a large quantity of 24 LED panel (SMD 5050) over eBay to upgrade all dome/wall/cabinet/exterior lights of my trailer to LED (cool white). I order them from eBay and they are AWESOME. ...

Been there, done that. These LED strips
a) don't use 3M VHB tape but something much inferior
b) don't use current regulation but a dropping resistor.
the combo is a bad combination. LED current is an exponential function of applied voltage. LED's are 10-15% efficient, the rest is heat. Fine at 12V nominal, charger goes to 13.6 or 14.4 and you found out what happens. In some cases the LED will get hot enough to melt the solder.
short term solution is to use silicone adhesive or real 3M VHB tape.
If you don't do much camping (a few weeks/yr) they may hold up.
We do lots of dry camping. These ended up very short lived. (well about a year but that was over 100 days camping). when hooked to shore power or generator or solar charging the batteries in bulk mode, the LED's overheated and eventually got very dim and finally failed.
solution is to spend the bucks and get arrays that have a built in current regulated supply.
