Peterson 116A Clearance Marker Light w/ Reflector 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.

Surface-Mount Light

Surface Mount Trailer Light Installation Diagram

Surface-mount trailer lights install using a flange or bracket with mounting holes. These lights lay flat against the trailer surface and only require a small, often pre-existing hole, for wiring. Mounting hardware is used to secure the light to the trailer.

This is an EXTREMELY difficult light to find. I called by boat trailer manufacturer (EZ Loader) and they said that Wesbar made these wedge lights since the early 1990s and 2 years ago they had stopped making them? This light is a PERFECT replacement to that Wesbar wedge light that has been discontinued. E Trailer is an AWESOME company. This is my 5th order and I cant say enough good things about this company. Extremely helpful folks - fast shipping and superior products. REALLY pleased.

You guys are awesome with GREAT products and serviceTHANKS

I ordered these lights for my boat trailer. The description of these lights were very detailed and made me confident they were exactly what I needed. I recieved the lights in a timely manner and they were exactly what I needed .

etrailer had the lights I was needing for my older boat trailer.. Great price, fast shipping.
David R - 09/05/2021


Lights are pretty much what I was looking for but was surprised to see that the holes for mounting them are pretty small. Since these are submersible and going on a boat trailer frame the supplied wood/sheet metal (?) screws won't do me any good and would like to put in a little larger screw in them. Maybe you can tell me how much larger I can make the hole without compromising the light itself.

I have contacted the manufacturer and they have confirmed that they measure the mounting holes with a caliper and the diameter of the head cannot be larger than 0.25 inches, but you can go longer than the 0.75 inches length of the screws provided. The current screw specs are 6-18 x 0.75 Type A., Type 1 cross recessed fillister head tapping steel screws with black oxide coating.

Nice bright and clear nice price use as clearance lights on my boat trailer

Dennis B - 09/03/2021


Lights were a perfect fit and look Great on the trailer.
Fast Shipping, will definitely do business with etrailer in the future.


Great replacement when the jack wheel accidentally cracked the old one.


Fit was perfect matching the existing one on opposite side, holes line up for mounting and wiring.


Shines brightly and hasn't failed yet on my boat trailer.


WOW!Your service is very prompt!I look forward to doing business with etrailer again. The marker lights you sent for my boat trailer work fantastic! Thanks again for the quick service.


I am very thankful that etrailer carries a replacement light for my "not so new" boat trailer (1999 Prestige). The M116A Wedge Amber Side Marker light is nearly the exact same light my boat trailer came with, including the fastener holes. The video and technical information helped me decide to buy from etrailer. Keep up the good work etrailer. I would definitely buy again from etrailer.


good selection good price delivery 1 day earlier than expected. Only drawback was one of the teardrop light lens had a crack in it on bottom side and 2 ea mounting screws missing


I purchased 2 Peterson wedge style clearance lights for my boat trailer to replace the original lights.
I ordered online and they arrived within a week.
The installation was quick and easy!
This is the 2nd order Ive placed with etrailer but it wont be my last. Very happy with the products and fast delivery!


Fit my 2010 Stratus boat trailer perfectly. Just ordered a second one for the other side.


It’s a great replacement trailer light. I did wind up switching mine to a LED version i stead though. The swing away tongue kept breaking the lens se.


The 1st light didnt work, thank goodness I ordered 2 and the 2nd 1 did. Not worth the $13.21 I paid to send back. I ordered close to $300 and this was my only mishap. Everything else was shipped faster then that other online retaler, made in USA (I'm a disabled vet & only buy American) and looks and fits perfect. Hopefully someone at etrailer will read this and make up the $13.21 but if not I'll survive.


Still working and looking great


Just recently bought a great used boat but the front drivers wedge light was broken. Found this on etrailer and ordered, it was delivered quickly and worked perfectly. Thanks!


Product does not work - will be returning for a refund.

You may want to double check wiring connections as this is the most common issue. I well send your information to our customer service team to have them reach out to you soon.
-- Etrailer Expert Brooke M - 08/13/2022


Light were a direct replacement for my EZ Loader trailer. Came with screws and fit without additional drilling required.


On time. Exactly what I ordered. Worked first time.


Fast shipping and products are just as described. I would buy from them again in future if needed.


Perfect fit.


The wire that comes out of the back is glued in permanently and it sits higher than the flange all around the outside of the light so the light wont sit flush against the trailer. The solution is to drill a hole in the trailer or deal with it. Bad design

Thank you for your review. This does need to be bolted in. Here is an install video of a similar product but it is installed the same as the one you purchased:
-- Etrailer Expert Sierra K - 08/02/2021


shipping was a little slow, but thats usps for you. light was perfect I would buy from you again for sure thanks


etrailer was the only supplier I could find that carried this specific fixture to match an older trailer.

  • Troubleshooting Marker Light That's Causing Fuse on Tow Vehicle to Blow
    Since you're replacing an existing marker light instead of adding additional lighting, it's extremely unlikely that you're drawing too much power on the running lamp circuit. Instead, I'd look for a short circuit somewhere in the running light circuit. Look for loose wire connections, pinched wires or wires with cracked or worn insulation that would allow the copper wire to short out on the trailer frame.

  • Replacement for Amber Side Marker Light On Eagle Boat Trailer
    The Peterson Clearance or Side Marker Trailer Light w/ Reflector part # M116A is an older style light which appears to the same as the one picture so it will likely be an exact fit replacement. That said, I have attached for you a video which shows exactly where each measurement is taken.

  • Boat Side Clearance Light Replacement for Wedge Shaped Amber Clearance Light
    Based on what you described the part # M116A is the closest option we have for a replacement as it's close in dimension and in shape.

  • Is Amber Tear Marker Light M116A a 1-Wire Design
    Peterson Teardrop Marker Light # M116A is a 1-wire light, meaning that the ground is established by the metal mounting flange and the 1 wire is for +12V. This means the flange should ideally make bare metal to bare metal contact with the mounting point on the trailer. It is also a good idea to prevent corrosion by applying dielectric grease # 11755 at the installation point.

  • Availability of Triangular LED Trailer Clearance Light M116A in Red
    The closest thing we offer to the # M116A in red is the part # CBL22RB which is a similar truck bed cab light.

  • Recommended LED Wedge Clearance Light For Trailer
    The closest LED light that we have to the # M116A is the Triangular LED Trailer Clearance and Side Marker Light or Truck Cab Light, 15 Diode - Amber # CBL22AB. This has a wider design and is not reflective. This is a very nice light that I recommend if you are looking for an LED alternative to your current light. This is a submersible light. Unfortunately I think you will need to decide between LED and Reflective incandescent as you can't just change out the bulb on a sealed unit.

  • Do I Have to Replace the Wedge Lights on my Boat Trailer with Wedge Lights for LED Upgrade
    When replacing trailer lights (with or without LED) you don't necessarily have to get the exact same light or even light style. Most people like to keep the same style and size so that they don't have to mess with repainting or making sure that everything lines up correctly. If your current light has the same dimensions of the Peterson Sealed Wedge-Type Clearance Marker w/Reflex # M116A then the Optronics Sealed, Miro-Flex, Thin Line, LED Trailer Marker # MCL63AB has slightly different...

  • Is The Triangular Peterson M116A Light Available In Red?
    Though I may have an alternate that will interest you, Peterson does only offer the Clearance or Side Marker Trailer Light # M116A in amber, unfortunately. With that said, check out the Optronics Triangular Trailer Clearance and Side Marker Light # CB22RB. This is quite a bit different, but if you were looking for a triangular red light, this will be the best option we currently have available.

  • Wedge/Teardrop Trailer Clearance Lights Available In Red
    The only wedge/teardrop style lights I can find in red are going to be Truck Cab Light Kit # PP20-215. The lights are 4-5/8" long x 2-1/16" wide x 1-3/4" tall and come as the set of 5. Since they are 12 volt, 2 wire connections you will be able to splice them into the trailer wiring. The Peterson Clearance or Side Marker Trailer Light # M116A is only available in amber.

  • Does the Peterson m116a Clearance Light Come in Red?
    I checked with Peterson and confirmed they do not have the # m116a clearance light in the red lens at this time.
