The telescoping stern light has failed on my heat. Looking for a replacement. I know they are no longer made. What are people replacing theirs with?

I am pretty sure that I have a used one in working condition, but to answer your question, most have been replaced by the manual telescoping one

All-Round LED Plug-in Mount Stern Light - Innovative Lighting

Yes I have, I used the manual innovative unit mentioned above. They make an adapter plate you buy separately that makes it so it will fit in the original hole. If memory serves you need it to take up space as the hole was larger.

I have a 2002 Rage and I have been searching for a replacment lens due to mine braking at the threads. Does anyone know if they make parts for these??

Nordic has plenty of them last time I checked. Give Mike a call
