Trident inside lights

Hi there,

parked up campervan and battery flattened.

can someone tell me about inside lights on right and left in the living space area. i have a red dot at top of switch, is this on or off please. cant make to much sense of manual as i'm female .

has just come back from service so all should be well, will collect the bill friday.

whilst here, can i enquire where people buy their chemical stuff for bi-loo.

anything else i can think of well, i shall just ask,

thanks all.

Diane
