[In] trying to buy a replacement bulb for my 1984 Outrage bow navigation lamp, there are no markings on the bulb (other than USA), but it's a dual contact, bayonet base. The bulb is the same size as a 1157 trailer bulb and has one filament. West Marine lists a half dozen DC [bayonet] bulbs. but [I am] not sure which I need. Any help appreciated.

It is probably a #90.

Here is the link to the Perko #337 bayonet style bulbs.
The #90 is listed as 7 Watt

I would be interested in what the original bulb was also. Thanks for bringing this up.

I went out to the garage and took both covers off my Bow Nav Lights. Both bulbs were #1152. I am not sure if these are original as I am the second owner of this Outrage 18.

I did a little research on the bulbs.

#1142 = 18.4 Watts, 1.44 Amps
#1152 = 17.1 Watts, 1.34 Amps
#1157 = 27.0 Watts, 2.01 Amps

Can anyone else confirm what bulbs they have in their Bow Nav Lights?

My [1983] Outrage uses a T1004 Bulb.

jbarrow--Are you the original owner and know for a fact that these are original?

I know that LHG is the original owner of an Outrage 18' and 25'. He also has two brand new, in the box, Wilcox Crittenden Bow Navigation Lights.

LHG--How about it. Can you tell us what light bulbs your Outrages have and even better, what bulbs are in the brand new boxes?

LHG posted 04-04-2005 02:50 PM ET (US)     Profile for LHG    
Joe - I'll take a look for you. I do remember that I had to replace one of the lamps on my 18 Outrage, and that Lauderdale Marina wanted $7.50 for one. Then I found the same lamp in an auto store for about $1.50! I seem to remember it being a single contact lamp? I'll check the originals.

Do you want some photos of my new spare ones, from the original box?

Joe Kriz posted 04-04-2005 03:19 PM ET (US)     Profile for Joe Kriz  Send Email to Joe Kriz     

I will take all the photos you can send me of the bulbs, boxes, lights, etc. Thanks

Ok, Joe had it right with his 18. I checked my box of brand new fixtures, and 1152 is indeed the original lamp. The lamp also shows markings of 12V 21CP (candle power).

Joe Kriz--I'm not the original owner and I don't know if these are original. I am wondering though, how did you research the wattage and amps of the lamps? I would be interested in what a T1004 puts out. My bulbs are 10-years old and still working well. Both are dual contact with what appears to be a brass base.

LHG--Is the 1152 a dual contact or single contact? I recently had to rebuild my starboard [sidelight lamp]. I did a fair job, considering what was left of the plastic. Any interest in selling your pair in the box?



LHG posted 04-05-2005 07:59 PM ET (US)     Profile for LHG    
Not interested in selling, but the lamp is a two contact base.

jbarrow, (Jack)--I puched in 1004 miniature bulbs in Google and came up with some info.

I did this with the rest of the bulbs also. It took quite a bit of digging to find out all the info. Some sites had the Watts while others had just the Amps, etc.

I did find out that the 1004 had .94 Amps. I never did find out the wattage on that bulb.

Here is the chart from above with the 1004 added:

#1004 = ? watts, .94 Amps
#1142 = 18.4 Watts, 1.44 Amps
#1152 = 17.1 Watts, 1.34 Amps (original bulb)
#1157 = 27.0 Watts, 2.01 Amps

Thanks for all the info re the lights. One more question. Looks like the 1152 is the original bulb but West Marine does not list that bulb. They do list the 1004 and 1042, both of which are dual contact, bayonet base. Will both these fit and work, just with slightly different brightness due to different watts rating?

If the answer is "no", where can I purchase the 1152 bulbs?

Chicago Miniature Lamp (CML) has a very comprehensive catalogue of miniature electric lamps and replacement bulbs:

Some caution should be used when replacing the miniature electric lightbulb in your navigation light fixtures. The lenses in these lamps are typically made of plastic. If a bulb is used that has excessive wattage, it will generate too much heat which can damage the plastic lens, either discoloring it or possibly melting it.

On the other hand, a proper replacement should be used to maintain the necessary light output. Navigation lighting that is too dim is not any good, either. I would not rely on the existing bulb for guidance; it may have been replaced with the incorrect bulb sometime previously. On quality navigation lanterns like those used on Boston Whaler boats, the manufacturer usually has some markings on the lamp fixture to indicate the proper replacement bulb type.

Here is one place but the price isn't cheap:

I would try your local Auto Parts store. If they don't have it, maybe they can order it.

I know mine are Brass on the bottom and I see some advertised as "Nickel Plated" over brass.

I just read jimh post while composing this.
Here is the direct link to Chicago's #1152 and others.
It states on that site that the 1152 has 21 CP (Candle Power) just like LHG's brand new bulbs in the box state.

Mine also have silver color bases, so maybe they are the nickel coated version?

Don't know that anything was resolved in this thread but my [1986] 18 Outrage had the 1152 bulb in it, at least on the port side one that was blown. The local CarQuest and NAPA store don't carry these bulbs--not even in their warehouse--and looked at me sort of cross eyed. The NAPA guy was able to cross reference to an 1142 which I bought. I'll report back on how it works after the weekend. -- Bud

Bud--Make a run up to Wolf's in Benton Harbor.

They carry the correct marinized bulb and are inexpensive (be sure to check ALL of the packages as they are quite often marked differently).

The 1142 bulb seems to work just fine. I only observed in daylight, but they are *supposed* to be brighter.

The eqaution for DC power is Volts X Amperes = Watts.

Glad to find this thread on replacement nav light bulbs for classic outrages.

I rewired my [navigation lamps] to my new DC Sub-Panel and toggle switch. My port light did not work. Inspection of the [lamp] showed much corrosion, so much that one bulb was completed destroyed during the removal process. Unrelated to bulb destruction, note to anyone new to these [bayonet base] bulbs: they do not unscrew out but rather turn 90-degrees and then pull straight up.

Once the bulbs were removed I physically cleaned out the sockets with sand paper wrapped around a pen. I purchased new 1142 bulbs--1152s are not stocked locally-- greased them up, and installed the replacements. Hopefully these greased bulbs will last much longer.


jimh posted 08-27-2010 07:25 AM ET (US)     Profile for jimh  Send Email to jimh     
Avoid putting grease on the glass envelope of the light bulb.

A bayonet-base lamp typically has to be pushed down slightly in its socket then rotated about 30 to 45-degrees to be removed from the lamp socket. The lamp socket determines how much rotation is needed, and also which direction of rotation is needed.

If replacing a light bult with one that consumes more power, heed my warning above about the extra heat that will be generated. The tinted plastic lenses in these old navigation lamps are very difficult to replace. I would hate to see one softened or melted from a bulb that was too hot.

Thanks, Jim. I greased only the base but thoroughly.

As for the power, from the information earlier in the thread the 1142 uses only 7.6% more Watts than the 1152. Since the 1152s were not readily available and LED Nav lights with completely new wiring throughout the boat are on my Spring list I went ahead with the 1142s. Will report back if I encounter any problems.

#1142 = 18.4 Watts, 1.44 Amps
#1152 = 17.1 Watts, 1.34 Amps (original bulb)

[One year later...] Did [irishcreamer] have any [problems due to overheating] with the higher wattage bulb? I need to replace one, as well, and the one I pulled out--an 1142--was really black. I'm wondering if it got too hot. Thanks,

They get black because the tungsten filament vaporizes a
little and condenses on the inside of the glass. Find a
a halogen bulb, the halogen prevents that.

I was servicing the Marinium sidelight lamps on my 1986 Outrage 18 today. As the third owner of this boat, I found GE 1152 bulbs in both sockets.

I also noticed that the Marinium covers have the following lightly cast in the underside (non-polished side) of the cover:

Port Bow Light Casting:
P A 1.5
1152 Bulb

Starboard Bow Light Casting:
A 1.5 S
1152 Bulb

Surprisingly, the underside of the cast cover defines the bulb number 1152 with the word Bulb, a "P" or "S" for Port or Starboard, plus possibly an Ampere designation of 1.5 or 1.6 (it is difficult to determine a .5 or .6).

I thought I would share this discovery since I couldn't find it elsewhere on the site.

Great information. Thanks for appending it to this thread. As I mentioned ten years ago: "On quality navigation lanterns like those used on Boston Whaler boats, the manufacturer usually has some markings on the lamp fixture to indicate the proper replacement bulb type."

Very timely thread since the port light on my '78 Outrage is out. I went looking on Google and found this, a bit pricey [at $9]:

I think I'll stay with cheap old technology.

jimh posted 06-02-2015 09:54 AM ET (US)     Profile for jimh  Send Email to jimh     
The "old technology" --in this case a miniature incandescent lightbulb--is not as cheap as it once was. Here are two prices for an 1152 bulb:

First, the generic part, for $2.40:

Next, a specific brand (GE) with a specific grade, for $10.31:

Also, in the ten years since I posted a hyperlink to CML's bulb selector, that resource has turned into a dead link. CML, the company, has apparently split into two division. The company selling old-fashioned incandescent miniature lightbulbs is now called VCC and has a website at

I used their product search function to attempt to find an 1152 bulb, but I could not find one listed as a 12-Volt bulb.

Using GOOGLE Search I found many retailers of 1152 bulbs. Here is a comprehensive listing of the characteristics of the 1152:

#1152 -- Minature bulb Ba15d Base
12.8-Volts, 1.34-Ampere, 17.152-Watts
S-8 bulb, double contact base
21 MSCP (mean spherical candle power)
C-6 Filament
500 average rated hours

You can find generic branded #1152 for under $1. See

The following link takes you to the GE Lighting specification sheet: Dispatcher?REQUEST=COMMERCIALSPECPAGE&PRODUCTCODE=26945 has the original for $5.99 each, but of course there is a shipping charge.

jimh posted 06-03-2015 06:23 AM ET (US)     Profile for jimh  Send Email to jimh     
Has anyone a good reference to define exactly what is a "C-2R filament"?
Hoosier posted 06-03-2015 08:01 AM ET (US)     Profile for Hoosier  Send Email to Hoosier     
The GE spec sheet filament doesn't match the one cited above. Could they have different "Lumens" ratings? I would expect all 1152s to be the same, otherwise they would have different numbers.
vkr posted 06-04-2015 09:37 PM ET (US)     Profile for vkr  Send Email to vkr     
I am pretty confident the GE specification sheet is accurate. However, the double filament image that is shown for the GE 1152 bulb on the www.elightbulbs website appears to be wrong. The GE 1152 bulb has a C-2R filament. The C stands for a "coiled" filament. I'm not sure about the other letter and number designation.

I ordered this GE 1152 or 26945 from elightbulbs and received the expected single filament bulb with the proper base.

I'd defer to the G.E. specifications in preference to any retailer's website specifications.

Re LUMENS and CANDLE POWER: I think the relationship is

1 Candle Power = 12.57 Lumens

This is suggested by many sources, e.g.:
