View Full Version : Navigation light socket repair bulb wattage etc...

06-19-2010, 06:49 PM
One of the sockets on the nav light has failed.
So I found out the bulb no. 1142 is discontinued and was wondering about switching to an 1156 socket and bulb.

1142 is 18 watts.
1156 is 27 watts.

I can still get 1142 sockets at Advance auto, but I cant get the bulbs locally, Amazon sells them etc... and on a car forum it is stated the 1142 bulb is discontinued.

So what bulb socket combination should I pursue on this repair?

Shooting from the hip, I'd say that if you have the battery capacity to go with the 27 watts and you are not going to melt the lenses, then go that way, but change all the light, just to avoid people confusing the signature of your boat and to simplify your spares.

Use a GE 26917 and it should screw right in.

The lenses are glass, housing is bronze.
Tear drop type of light.
Found some people are using 1152 and so far no one locally carries either 1142 or 1152. I like the dual wire design instead of grounding the socket.

GE 26917 is an 1142 type bulb. Still I would like to get these locally.
I might have to buy the Amazon 10 pack
I could see this being tough to source locally and me being out on the water and no one has these bulbs anymore.

I would say LEDs as well. But the one you (Chuck) show may be directional in the wrong direction. But using LEDs will consume far less power. Look here:

I like the idea of LED, low power and long life.
The way these NAV lights are made it has to shine out boat forward, which would be right angles to the bulb base and out to the P and S sides meaning a non directional LED light. Also, there is not a lot of room in the glass housing for an LED bulb with large protrusions, like some LED I have seen.

question is, would it be too long?


this shows a size schematic

Working on old cars NLA bulbs (among other parts) are something I deal with on a regular basis. Here is a link to two sites I use to source hard to find bulbs. The first link (candlepower) sells quality German made bulbs. The second link is to a real great resource for searching out bulbs. It has a tremendous amount of information available. I've linked the page for that bulb specifically.



I've ordered from both, never had any problems. Looking at it I'd say ordering a handful from Don might be the best way to go.

looks like the 1142 is 2 inches long, so the LED

bulb will fit being a little shorter.

the 1004 bulb also would work and is a lesser intensity. That chart shows the 1004 being for marine lights so maybe the 1142 was an improvement someone else put there.

Your 18 watt incandescent bulb would equal a 3.4 watt LED which would equal 240-270 lumens....pointed in the right direction.....
