Features to know about

Reliable Visibility and Style: Amber Teardrop Marker Light

This Peterson teardrop light gives your trailer a clean, classic look while keeping it visible at night. The 5-3/8" long x 1-13/16" tall design uses an amber lens over a bright incandescent bulb to serve as either a clearance or side marker light. The built-in reflex reflector means you don’t need an extra reflector plate. It’s P2 rated for proper light spread and is fully DOT compliant, so you get both function and peace of mind in one unit.

Protected From Water and Road Spray: Sonically Sealed and Submersible

Wet conditions are no problem here. The housing and lens are sonically sealed together to create a single waterproof piece that’s submersible. That keeps water out and protects the bulb and wiring even when the trailer is exposed to rain or water spray. It’s a dependable pick for anyone who wants lighting that holds up through tough weather or washdowns without fogging or shorting out.

Simple Grounding Setup: 1-Wire Design That Mounts Cleanly

Installing this light is straightforward thanks to its single-wire design that grounds through the mounting flange. You just connect the +12V lead and secure the housing with two #6-18 x 3/4" screws (included). Because it uses the metal flange for ground, a bare metal contact point ensures a solid connection every time. The surface-mount style lays flat against the trailer body and only requires a small hole for the wire pass-through.

Built for Tight Spaces: Low-Profile Teardrop Shape

The wedge-style teardrop shape makes this light ideal where space is limited or when you want something that blends in instead of sticking out. At only 1-1/2" thick, it sits close to the surface and adds visibility without snagging on anything. The 3-1/8" mounting hole spacing makes it easy to replace older lights without modifying your trailer’s setup.

Dependable Performance: Proven Incandescent Clarity

Peterson’s incandescent build provides consistent brightness that’s easy to see from straight on—perfect for marking trailer width or corners. Designed for 12V DC systems, it’s ready to wire up and go, keeping your trailer visible trip after trip with simple, proven lighting technology.

Great replacement for my boat trailer



by:

These wedge-shaped marker lights are nearly impossible to find, though they were widely available just a couple of years ago. etrailer.com has them in stock for a reasonable price - lucky for me since I have two of them on my boat trailer and haven't found a decent substitute. I did need to drill a new hole in my trailer since the screw mounting pattern is smaller on these lights than the original lights, but that was easy. Overall very satisfied - prompt delivery of quality lights at a reasonable price - can't get much better than that.

One year later and still working well!



by:

Ordering process easy. Searched all of Tulsa area and was told by trailer companies that the lights I needed on my 15 year old boat trailer were no longer available and that I would need different lights. AND...drill new holes to fit new lights in my restored trailer, which I did not want to do! So, I found etrailer in search engine, found the amber lights quickly, and ordered same day. Received the 2 trailer lights in good packing order and within expected time of less than 1 week. Will order any needed future lights from etrailer.com!

Good quality

Perfect - Thank You



by:

Great place to shop at. All trailer lights changed.



by:

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



by:

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.



by:

The light was easy to adapt to my boat trailer. It works great as a side marker light.



by:

I bought 2 for my boat trailer and one has stopped working already . Plus the same basic light same brand did not have same hole pattern had to drill to make light fit .



by:

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!



by:

ARRIVED AND INSTALLED



by:

mounting is different than the original.
Doesn't work unless I want to put more holes in my trailer.
Price was okay not an issue



by:

I was hoping it had a center stud bolt to mount like my original one, but can't find one. I just drilled two holes and made it work.



by:

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

etrailer had the lights I was needing for my older boat trailer.. Great price, fast shipping.



by:

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.

  • Can Peterson Clearance or Side Marker Trailer Light Bulb Be Replaced With LED
    Hey Anthony! The Peterson Clearance or Side Marker Trailer Light # M116A is sonically sealed. This means the lens and the housing are basically fused together. It would be difficult to open, could actually damage the light, and once you open it the submersible quality would be lost. It doesn't look like we have an LED version in this size/style so sticking with incandescent would be the only option. Where are you taking the Ranger next?

  • Looking For A Replacement Wesbar Side Marker Light For My Boat Trailer
    Hey Joe, The closest light I can find to the size of your current Wesbar is the Peterson # M116A, which comes in at 5-3/8" x 1-13/16". It does use a 2 hole mount so you would need to drill another hole in order to install. We do not carry the Wesbar lights you have on your trailer now. If you want to email me some photos of your current ones I can see if I can find a replacement that looks more like your original.

  • 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.

  • 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...

  • 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.

  • Is The Peterson Clearance Light M116A Offered In Red?
    The Peterson Clearance or Side Marker Trailer Light # M116A is a pretty unique design. Unfortunately, they are currently only offered in the amber color. However, we do have a couple options you may want to check out. I have these listed below: Optronics # CB22RB Optronics # MC70RB Peterson # 424600 The # CB22RB will be the most similar, but they are still pretty different. Personally, I prefer the Peterson # 424600 as it has a classy/vintage kind of look to it. Granted, if this isn't...

  • Recommended Amber LED Boat Trailer Clearance Lights
    Hey Mike! The closest amber LED light I have to what you're looking for is the Peterson Clearance or Side Marker Trailer Light w/ Reflector item # M116A. It has mounting holes that are 3-1/8" on center. Most of our amber LED clearance lights have 3" on center mounting holes. This is the closest one to 3-1/2".

  • 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.

  • What Size Screws Are Included With the Peterson Clearance or Side Marker Trailer Light # M116A
    The Peterson Clearance or Side Marker Trailer Light # M116A comes with 2 screws that are #6-18 thread size and have a 3/4" length. Depending on what you previously had you may need to drill out the holes to make them larger and allow the new screw to thread itself into the trailer frame or tap the holes for the threads.

  • 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.

  • 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. The dimensions on this light are 5-3/8" x 1-13/16" so if you we are trying to match as close as possible there are a couple of potential options. The Pacer Performance Hi-Five Truck Cab Light Kit - Teardrop Style with Red Lens # PP20-215 Light has dimensions: 4-5/8" long x 2-1/16" wide x 1-3/4" tall The red side marker teardrop lights we offer, part # CB22RB have a different...

  • Availability of Triangular LED Trailer Clearance Light M116A in Red

  • 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.

  • 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.
