Saw an RSM250 in a LFS today, fully stocked and looking good. Interestingly it had an Aquabeam 600 ultima LED unit fitted. The fixing lugs are a perfect size to suit two of the flourescent tube cover lugs and the power lead ran straight out of the accessory hole. I asked wether it was too close to the water, but the guy said it was fine and had never been a problem. Anyone else tried fitting one of these ?
