LED Replacement bulbs in Nav lights

cjjjdeck Member, Moderator Posts: 1,872 ✭✭✭✭

I’m just curious.  I‘ve been thinking about changing my incandescent navigation bulbs to LED replacement bulbs (not change the fixtures).  The two navigation lights in the bow use a 31mm Festoon Bulb (and those fixtures sure get hot!). The bulb must be rated for a range of 1 nautical mile minimum (although I really would like it to be 2 nm rated).  I’ve been doing some research on them and the couple I’ve found so far that have the range rating are significantly more money (like about $5.00 per bulb vs. over $25.00 per bulb), I just want to make sure I’m not missing some others to consider (maybe that’s the price you pay for marine grade quality and if so, I’m OK with that).  

Have any of you made the change, if so, whose bulbs did you use?

    @cjjjdeck I haven't but am interested in doing so as well.  Typically, the cost of LED bulbs vs their counterparts (at least in 12V automotive and trailer lights) are approx. 5x the price.  Now the marine grade may account for tin vs copper socket, etc which would again drive the price a little higher.  Given that, anything in the 5-8x range would be acceptable in my opinion, and possibly more for the additional range as its a brighter LED.

    My guess is $5-12 per bulb would be expected depending on the factors you've listed.

    Yes, I've done this with my nav lights and it works great.  In fact, the LEDs draw less current for a brighter shine.  Last forever.  Do it, it's cheap and worth it.

    I want to do that. Where did you find the bulbs at?
