hi,well thanks for the info!the reason i would like a zig unit is to charge the 12v battery unless i could find another way round it,you make it sound so simple, i could change the old dated strip light for a modern halogen light their are plenty on ebay as i presume it would just be a case of plugging the original wires in to it,i have seen some very nice 12v spots but i am not sure how to connect these wires as i would have to have new wires for them could i just run a live and a earth from the original wires for the strip light,or maybe be better to run a new wire from the fuse box,steve
