I’m going up my 1987 30U mast shortly, and think it’s a good time to replace my masthead incandescent lamp with an LED. The manual shows the lamp is an RZP-10-12 double contact indexed bayonette. I believe that a Dr. LED 8001757 model may be appropriate, but would like confirmation from someone who’s already done it before I purchase it and go up. Other makes/models to consider? Thanks for your thoughts.

Hi, I replaced my anchor light with a LED from West marine early last  
year. Don't remember exactly which kind it was but it works fine and  
is quite bright.

I replaced my original AquaSignal anchor light unit with the identical  
unit this Spring.  
But replaced the bulb that came with the unit with a Dr. LED bulb that  
was designated as appropriate for the particular AquaSignal unit.

Works great and the total investment (new AquaSignal unit and the Dr.  
LED bulb combined) was just over $100, not the $2/$300 or more you see  
for some LED units!!
