THE RESISTANCE OF A LIGHT BULB is very low, TWO bulbs = 1/2 resistance of 1; FOUR bulbs= 1/4th; put a bunch in parallel and it can very well look like no resistance; TRUNK LIGHTS can easily be left ON by mistake and NOT seen during daylight hours. (TIP: CONVERT TO LED BULBS); Check age of battery, water levels, corrosion, etc. NE cell low means a BAD cell. Get battery charged/ tested if not too old, otherwise replace. A battery switch can help greatly to reduce battery discharge from Propane Leak Detector, etc. while in storage unplugged
