I had a look at the voltage output to the led. it was at 4.6V to my idea it should be more like 2 volts.
considering that its just a plug in led to the main PCB it should be easy to just solder in the correct value to drop the voltage down. other than that justs use a torch off axis with a red filter on. works a treat for me and i can line the octans up in the middle of perth. easy done
