Wesbar Incandescent Clearance or Side Marker Waterproof Trailer Light Dimensions

Sonically Sealed, Waterproof Trailer Light

The waterproof construction of this light makes it ideal for use on trailers that may be submerged, like a boat trailer. The housing and lens are sonically sealed together to create a single unit, which means that water will not get into the light and damage the diodes or circuit board.

P2-Rated Lights

Diagram of light spread for P2 rated light

A P2-rated light produces a 45-degree angle of light to either side of its centerline for a total of 90 degrees of coverage. This beam pattern can be seen straight on, but it cannot be seen clearly from the side. So this type of light can be used as either a side marker light or a clearance light, but it cannot function as both. If you need both functions, then you must install 2 separate lights on your trailer - one as a front or rear clearance light and one as a side marker light.

Mini Trailer Clearance or Side Marker Light - Submersible - Incandescent - Black Base - Amber Lens - W003238

Average Customer Rating:  4.7 out of 5 stars   (103 Customer Reviews)

2-1/8" x 1-1/8" Rectangle. Waterproof, incandescent trailer light serves as a side marker or clearance light when properly mounted. Durable polycarbonate lens and housing. Stud mount with included hardware. 1-Wire design. P2 Rated.


I ordered a black base and I received a white base. I can get a white base much cheaper with free shipping on [online vendor], but I need a black base. etrailer was the only one I could find that had the black base light. Now I have to go through the hassle to return it and wait longer for the correct light. I’ll be calling ASAP.

Thank you for bringing this to our attention. Our customer service team should be reaching out to you in the near future.

Match to my Rocket trailer make sure you choose the LED version as they have a matching type with a bulb that I mistakenly ordered first.


This product is the OEM lights for my Ranger boat trailer. I was able to replace the light that was broken and perfectly match the rest of the lights on the trailer.


just what we needed


Just what I needed.


Have ordered items in the past. Excellent company. Always keeps you up to date on status of order. Highly recommended.

Working great after 1 year. Glad I chose your company for purchase.

E-Trailer is fantastic. Always have the parts I need at good prices. Sure you might find similar products at other web sites but remember, you get what you pay for. Service is outstanding. I send all my friends to e-Trailer.


I ordered both red and amber marker light for my trailer and was very upset to find the amber light only have a single LED and the red ones have 3 LEDs
The triple light bar and the red lights match but mow the amber don"t.
It looks bad on the trailer. The light all look the same when they are off.

Im sorry to hear your were displeased with the amber marker lamps you purchased. The lamp in question, part # W003238 is a single-bulb incandescent lamp, not an LED, which would explain why it didnt preform as well as the red LED lamps you purchased. The matching amber LED lamps that would match the red ones you purchased are part # MCL95AB. These lamps have 3 diodes, and performance-wise, would be a match for the other lamps.

Fast and reliable service plus a quality product! I will be sure to order all future supplies through

Thanks for the follow up. The product worked fine and I appreciate the high level of customer commitment.
NJC - 08/25/2018


The product is well constructed. I had to drill an additional hole in the trailer to feed the wire through. No big problem. On the original lamp the wire fed directly through the center of the mounting bolt, the new product it is fed from through the base and beside the bolt. My only real complaint is that it doesn't come with, or provide the option of ordering a connector for tying into the existing wiring. After five years the original connector was dry rotted and not reusable. Fortunately I had a spare connector for the job.


I thought the product could have been received faster and cheater if sent though U.S.P.Service. It was costly shipping through U.P.S.which item was small and light weight item! I thought bubble wrap envelope would have been my choose.


Exact replacement for the running lights on our trailer. Happy with the service and website.

Our replacement lights are perfect. No issues

Bought four for boat trailer, two red and two Amber. They are made fairly cheap but they were cheap. The wax on the back side to make it water proof was so hard when I moved the wire it cracked. Also there were holes in the wax around the bolt where water could get in. I filled the area with silicon to elevate the problem. Also the tin is so thin one crushed onto itself when I tightens he nut onto it. To my surprise they did work. Well you get what you pay for.


These look and feel like a good light for the money. I'm not a fan of a single bolt mount - holding the light in place. I anticipate having the light being inadvertently knocked off-center. Furthermore, there is not a ground wire on this light, thus you will need to wire the ground to a small screw on the back of the housing - if you have a boat trailer with fiberglass fenders.


Nice product


I would have liked to see this as an LED. You have LED in red but not amber.


You have the right replacement parts for my trailer and at a great price. I also glad I found your company on the internet. I will keep doing business with you for years to come.


Looks just like the original running li ght


The light does not come with a lock (any) nut for the through-trailer bolt for install. If this is a new install (or had to bust the old one off due to salt corrosion, etc.) you have to go shag a 1/4 lock nut.


Products arrived on time and were high quality. Have ordered from here once before and have not been disappointed.


Great item and fast shipping.


Received the order as promised and although I sold the tow dolly before I received them or had a chance to use them they look of great quality and I'll likely use them in the future.

I really like etrailer and toe information they provide.

Thank you!


Exactly like old lights but now can replace the bulbs. Installed perfectly in the old existing holes. I also purchased connectors in case they are ever replaced again.


the only problem I have with this light is if you don't put a washer on the bolt to space it out, when you tighten it it pulls the led away from the lamp body and kills the lamp. I have gone through 4 of these in a year.
