Hi all
I am going to change the nav lights on my 1987 boat. This boat has the individual vertical mount port/starboard lights. Have any of you replaced this style? If so with what. I have see the Aqua series 31 LED & the perko teardrop  shaped lights and a pair that are half cylindrically shaped lights. Those may be too large. I have the round vertical mounted ones.
Thanks for your help
Rod
