I bought both the left and right side trailer lights for my Nitro trailer. They fit perfectly! These lights do not come with the the 3-way molded connector that plugs right into the trailer wiring. I purchased heat shrink splice connectors (for 22 to 18 gauge wire) along with liquid electrical tape to attach my lights. Everything works great. Kudos to etrailer for the speedy delivery! 72741


My trailer lights are still working great! No problems with them whatsoever. Thank you.

Bought this as a replacement to a light I broke pulling my trailer through my gate. This product was half the cost of my local trailer supply stores. I like the LED setup. The lights run great. The only warning if your thinking about buying these type of lights and are switching from conventional lights is that these LED light require a ground wire from the vehicle and on the trailer frame to work. Could not be happier with the price or the product. 98034

Purchased to replace a broken light of same type. Have used these Wesbar submersible trailer lights in the past on other boat trailers and they perform well, and are reasonably priced. First order was not delivered due to an incorrect address that I had provided. Etrailer worked to find the lost shipment and got it returned to there warehouse for proper credit. Very helpful and prompt vendor. 127115

Ask the Experts about this Wesbar Trailer Lights
Do you have a question about this Trailer Light?

  • Changing the Bulb in the Wesbar Tail Light Capsule
  • The older generations of the Wesbar submersible low-profile lights came with sealed light bulb capsules that are not replaceable. If your capsule is sealed, then your best option is to replace the lights with new lights like part # 403026 and # 403076. The new lights come with capsules that allow you to replace the bulbs. The bulbs used in these lights are # A1157B and # 193.

  • Availability of Replacement Wesbar Trailer Light Capsule for a 1993 Four Winns Boat Trailer
  • The 102640 that you have referenced is for the older generation light like the Wesbar Submersible Low Profile Trailer Tail Light, # 403026, or # 403076. For your situation, the best option is to replace the tail lights with the newer models that I just listed. Unfortunately the capsules in the older units are sealed and the bulbs are not replaceable. Also, the replacement capsules are no longer available. The bulbs can be changed in the newer generation lights, # 403026 and # 403076,...

  • Upgrading Wesbar # 3504 to LED Lamps
  • We offer an LED version of that lamp, # STL17RB for the drivers side and # STL16RB for the passenger side. The Wesbar # 3504 lamps you have are not upgradable. If you wanted LED lamps, you would need to replace your existing units entirely.

  • Availability of Replacement Capsules for Wesbar Trailer Lights # 403076 and # 403026
  • Some Wesbar lights have a sealed type of capsule that you are describing, and they are not meant to be opened. Instead, you would need to replace the whole capsule. The good news is that Wesbar offers replacements that can be easily opened to change worn parts. If you have a Wesbar Submersible Low Profile Light # 403026 and/or # 403076, you can replace your capsule with part # 403356. This capsule opens and allows you to replace the bulbs if needed.

  • Is the Wesbar Trailer Tail Light # 403076 and Wesbar Tail Light Capsule # 403356 Waterproof
  • The Wesbar Replacement Tail Light Capsule, part # 403356, has an O-ring around the base of the capsule to seal out water. This capsule is designed to work with Wesbar Submersible Low Profile Lights, part # 403026 and part # 403076, made before 2010. The lights made after 2010 do not have removable capsules. The newer style light that has a light capsule that is not replaceable, but the cover on the capsule can be removed with 4 screws to gain access to the replaceable bulbs ( #1157,...

We have gotten back many reviews of these lights working just fine on Shoreland'r trailers. I will give you the dimensions of the lights so you can make sure they will fit your trailer.

  • Will Wesbar LED Wrap Around Trailer Lights Fit In Place of Wesbar Incandescent Tail Lights
  • If you are talking about Wesbar LED tail lights # 271595 and # 271594 then they could be used in place of light # 403026 and # 403076. All of these lights mount to bolt heads on the trailer. If you are talking about different lights, let me know what they are and I can determine if they are compatible.

  • Replacement Tail Light Bulb Capsule for an ATV Trailer with Sealed Watertight Tail Lights
  • It sounds as if you may have an older generation Wesbar Submersible Low Profile Trailer Tail Light, like item # 403026 or # 403076. If so, the light capsule inside the light is sealed and the bulb cannot be replaced. Your best option is to replace the tail light assemblies with newer models, like the part numbers I referenced that allow you to change the bulb.

  • Replacement Lenses for Wesbar Trailer Lights 403076 and 403026
  • We do have the lenses # 102639 and # 102641. These lenses are designed to fit Wesbar lights # 403076 and # 403026. I have linked the parts for you to view. You can also type in the lens part numbers in the search box and they will come up.

  • Availability of Wesbar 102640 Capsule Trailer Lights Assemblies
  • The newer version of the light you referenced would be the part # 403026 for the left hand side and part # 403076 for the right hand side. If you current light is sealed there would be no way to replace the inner capsule.

  • Wesbar Submersible Trailer Tail Light # 403026 Recommendation
  • You are correct, the light you have is very similar to the Wesbar Submersible Low Profile Trailer Tail Light # 403026. However, it is a different light as you noticed by the lens cover screws. Dimensionally they are similar yet still slightly different. The # 403026 is slightly bigger, but depending on your trailer it might still work for your application. The dimensions are 8 inch Wide x 2-7/8 inch Tall x 2-9/16 inch Deep for this tail light. I would check your trailer to make sure...

  • How to Wire Wesbar Replacement Tail Light Capsule # 403356
  • Actually, the Wesbar # 403356 replacement taillight capsule does have three wires, one of them is the white ground wire, which didn't show up too well in the main photo on the product description page. I've provided a photo for you that shows the ground wire a bit better. The red wire is the turn/brake lamp, and the brown wire is the running light circuit. The white wire is grounded to the trailer frame or a metal part that's in direct contact with the trailer frame. The replacement...

  • Replacing Bulbs in Submersible Trailer Lights.
  • I'm not certain which particular trailer lamp you're speaking of. I was unable to find a trailer lamp that uses the 2005 part number. If you're speaking of the # ST16RB, the lens is first removed by removing the 4 screws holding the lens to the lamp housing. Once the lens is removed, the 2057 bulb is easily removed by pushing the bulb into the socket, and twisting it a 1/4 turn. If you're speaking of a lamp like the older-generation Wesbar # 403026 that used a sealed capsule that looks...

  • Replacement Side Marker Lens Recommendation to Go Along with Side Marker Lens Part # 102641
  • The replacement side marker lens that would go along with the Lens part # 102641 that you referenced would be the Side Marker Lens part # 102639. Both of these lenses are replacement lenses for the Wesbar Tail Light Assembly part # 403076 and part # 403026.

  • Where Circuits Wire to the Wesbar Submersible Low Profile Trailer Tail Light # 403026
  • You are correct, the brown/green wire goes to the running light circuit of the taillight # 40306 that you install on the right side of the trailer and the brown/yellow wire from the trailer wiring goes to the running light circuit on the left side of the trailer. The running light circuit of the # 40306 is the brown wire. So both the above mentioned wires will connect to the brown wire. The red wire is for the stop/turn function. Most likely this will be a solid green wire for the right...

  • Replacement Lens Availability for a Wesbar Light # 403026
  • Yes, you can purchase just the lens for your Wesbar Submersible Low Profile Trailer Tail Light, part # 403026. You would want a Wesbar Replacement Lens Set, part # 053522033360. This will come with two replacement lenses, so you will have a backup lens in case the lens breaks again.

  • Can Trailer Lamps Approved for 80 Inch Wide Trailers Be Used on Trailers Under 80 Inches Wide
  • Trailers that are over 80 inches wide require additional lighting over and above what is required for trailers under 80 inches in width. Although the lamp you referenced, part # 403026 is rated for trailers over 80 inches wide, it can certainly be used on trailers that are under 80 inches wide. The over 80 or under 80 rating will have no bearing on the wiring connections. For this particular lamp, the white wire would ground to the trailer frame, the brown wire would connect to the running...

  • Installation and Troubleshooting Wesbar Replacement Lights and Right Turn Signal Not Functioning
  • The Wesbar # 403026 is considered the left hand side, the drivers side, or roadside. The Wesbar # 403076 is for the right hand side, passengers side or curb side. It should not matter which one is installed the wiring to the replacement trailer light is not side dependent. The only difference between the two is that the left hand side # 403026 has a clear section under the light that also functions as a license plate illuminator. If the turn signal on the right hand side is not functioning...

  • What Size Bulb Does Wesbar Submersible Trailer Tail Light Lens # 102641 Use
  • The Wesbar Trailer replacement tail light lens, part # 102641, which you referenced, fits over 80" red rectangular tail lights # 403076 and # 403026. These lights take light bulb # A1157B, which uses 8.3 watts for tail light function and 26.9 watts for the stop/turn function. I have included a video review of these tail lights for you to check out.

  • I could not find any information on a trailer light with part # 6554-tw, however, I did some research on your trailer and other trailers for the Boston Whaler 150 Sport and it looks like they use the rectangular submersible trailer lights like the Wesbar Low Profile Trailer Light, # 403026, that you referenced. This is the left side light, for the right side light, you will want part # 403076. To determine if these lights will work with your existing light brackets without drilling new...

  • Bolt Dimensions of the Wesbar Submersible Low Profile Trailer Light # 403026

  • Fastest and Best Way to Connect Trailer Tail Light Wires
  • Using butt connectors such as # 05731-5 is probably the fastest way to connect wires. Using a heat shrink butt connector such as # DW05744-5 would be a better, longer lasting connection. The white ground wire will need to secure to the trailer frame using a self tapping screw like # FA1131822.

  • Can LED and Incandescent Lights Be Mixed on Boat Trailer
  • It is certainly possible to use both LED-type and incandescent-type lighting at the same time on a trailer but I recommend you stick to one type or the other. LEDs are roughly 10-times as efficient as the incandescent type bulbs, and this means that in certain cases (depending on the number and placement of the lights within the overall trailer wiring) if you mix them you could find that some of the lights will be substantially brighter than others. The exact way the trailer is wired will...

This lens was designed to fit the Wesbar over 80 Inch Tail Lights # 403076 and # 403026. If the tail light assembly is still on the trailer, there should be a manufacturers name and part number stamped or printed somewhere in the tail light housing. The manufacturer and part number is the best way to find a replacement...

  • Troubleshooting Trailer Lights That All Go Off When Brake Pedal Is Pressed
  • The problem you are having with your trailer lights sounds like a ground wire problem. The first thing I would check is the wires. Look for any place you have a loose ground or if there is corrosion or dirt present that would not give you sufficient ground. If you have a tilting trailer bed or tongue you will need to run a jumper wire from the tongue to the trailer bed to make sure you have a solid ground. The next thing I would suggest to check is the harness you are using. You will...

  • Replacement Tail Light Options for 2002 Pro Craft Boat Trailer
  • My technical contact at Wesbar informed me that the submersible light that you have was discontinued a while back so replacement lenses are unavailable.

The Wesbar Submersible Right Hand Tail Light # 403076 that you referenced is the closest they currently have to the one that you have on your 2002 Pro Craft boat trailer.

  • How to Pick out Replacement Bearings for Tracker Boat Trailer
  • The best way to find the correct replacement bearings is to get the numbers stamped onto the metal of the inner and outer bearings that are currently on the trailer. If you cannot read those numbers your other option is to measure the spindle of your trailer with a micrometer to get the diameter of it where the seal, inner, and outer bearings ride. See picture.
