another weekend booked at bank hol, and not on EHU. so my cousin mentioned that he had a good 12v large battery, and said I could put this in the TT , and use it to run a light from. My questions are, how easy would it be to rig a light to it, would I still need an inverter ? how would a table lamp connect to it? also if I just bought a 150 watt inverter from say maplins, that plugs into the cigarette lighter, how long could I run a table lamp off it before I was reaching a danger point on my cars battery?

it's only a light I need, for a couple of hours to read with, wash up etc?? your thoughts please fellow campers

OK

For a start go for the 12 v batt if you can, and make sure its  FULLY charged before you go. You can use an inverter and the use a normal light, but its much, much better to use a 12v one ( cost about a tenner ? ).

Fully charged the battery will be fine for a weekend, even using the inverter and a normal lamp, but as i said the 12v light would be a better option.

Many 12 v lights have  crocadile clips that connect to the battery direct, or if you use an inverter they will have appropriate connections. If you stuck give me an email.

Have a good one....

I use a 12V car batt for running all my lights (12v fluorescent type) and run a small black and white TV from it for a couple of hours over a weekend, and do not notice any drop in the brightness of the lights.

Hope this helps.
