I HAVE STRONG OPINIONS ABOUT AUTOMOTIVE LIGHTING!
Just thinking over a beer about a 777 fire back in 2007…

"The P200 ELMS (electrical load management) was removed and found to have suffered extreme heating and electrical arcing. Moveable contacts within each had been destroyed. Busbars in the vicinity of the RBTB had insulation burnt off. The failure had obviously occurred within either the RBTB or RGCB.
…
The 777's two components had been in situ since manufacture and had completed 43,519 flight hours (6622 cycles). They have no overhaul or inspection period stipulated.
Prior to this particular accident, Boeing had been investigating 11 similar power panel overheat events involving the P200 and P300 panels. Those 11 events all involved an ELMS II panel.
…
The MEC (main equipment center) has no fire extinguishing system and it is located immediately below the flight-deck. Inflight the compartment is well ventilated for cooling purposes and these flows would have acted as a fire accelerant, as per the Canadian TSB's findings on SR-111."
