possible fire hazard lighting outlaw etc.

during the process of changing to led bulbs, my 2013 outlaw has a sconce ( just got it in march) lighting fixture , it has a plastic white tube inside the glass that defuses the light, the older bulb had started to melt this plastic tube.

My Hurricane (2014) has a double pancake light installed vertically just behind passengers seat... As I use that seat for our seasonal trips as an 'office - the light got a lot of use. It definately doesn't vent properly in that orientation - and started to melt/discolor the clean plastic lens.
Definitely cooler on LED now.

Heat certainly not good - but long way from melting to ignition...
Some examples:

Well... that table looked a lot better in the posting window... lol
for each - first line is melting temp, second is ignition...
Temps may be in Celcius - but real point is the difference between melting and ignition.
