Here are the waterproofed lighting strips mounted on the front of the ROV:

However, I'm somewhat disappointed by the lumens this is generated. The two strips are only consuming about 4 watts, so I'm guesstimating the lumens is in the order of 400 rather than 1,500 I'd hoped for (based on the LED specs). Although this is probably good enough for now, I need to work out what happened here.
