Just finished changing all interior lights to led and what a difference more light less power,the old lights were the two strip bulbs 4lights=12 bulbs no batt could hold out to them being on for a view hours,So went to maplins and bought led lights, I also have a 5 MTR strip led running all the way around the rear of the m/h it's like Blackpool at Xmas when they are all on,all in all a good job
