Peterson 119A Steel Armored Clearance Marker Light Dimensions

PC-Rated Lights

Diagram of light spread for PC rated light

A PC-rated light produces a 90-degree angle of light to either side of its centerline for a total of 180 degrees of coverage. This beam pattern can be clearly seen when you are standing directly in front of the light, as well as when you are standing on either side of the light. When properly installed, this type of light can function as both a front clearance light and a side marker light or as a rear clearance light and 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.

Video Transcript for Review of Peterson Trailer Lights - Clearance Lights - 424000

Today we'll be taking a look at the Peterson Armored Clearance and Side Marker Trailer Light. This is going to give you better visibility for your trailer, since it's going to allow other drivers to see where you are, and also stay safe and DOT compliant.It's going to be a metal housing to keep our light protected, and that's also going to be a surface mount design, so our ground connection will be made by that metal surface making contact with our trailer, so we'll just have one wire to actually connect. It does not come with any mounting hardware for this, so you will have to pick some up on your own. It has an incandescent bulb in there, and to replace that you'll just need to remove the two Phillips head screws in that housing.The nice thing about this light is that it does have a viber socket, which is kind of like a little rubber socket to help absorb any road shock to help make that light last a little bit longer, so you don't have to worry about replacing it prematurely. So it's just kind of a softer material to help absorb some of that vibration. Lens just goes right back over it, put our two tabs in place, and then we can tighten those screws down.The bulb type for this light is 168, which you can find pretty commonly.

Put our other bracket in place, and then we'll go over some measurements. This light is compatible with 12 volt DC systems, and it is PC rated, which basically means that it can be seen from both the front and the side, and be still effective as long as it's mounted properly.The overall length of our housing is about four and a half inches, and that curve to the other side, it's about two and a quarter inches tall, and then about one and a quarter inch thick. The distance between our mounting holes, which are diagonal from each other, but the distance between those two would be three and three eights inches. The diameter of each of those holes is about three sixteenths. The power draw at 12 volts is 0.35 amps.

It is made in USA.I'm going to hook it up to a power source here so we can see just how bright it is, my power to the wire there, and then my ground. I can really go to any of those metal surfaces, and that'll ground out the light. So you can see you turn on the power source, it turns on, turn off the lights in the studio and you can get a better idea of just how bright it is. You can see from the side, we still can clearly see that that light is on, so that's why we get why we get that PC rating.So it can be used as a clearance light and a side marker light at the same time, again, as long as it's mounted of properly. This works as an exact replacement for the Optronics number, MC-82AB, truck light number 203O9Y, and the Grote 45173.That's going to do it for our look at the Peterson Armored Clearance and Side Marker Light..

Got two amber lights for top of stock trailer. They were easy to install the metal frame should really help with the lights from being rubbed by tree limbs


Solid product with good quality materia l.

Lights are durable and made of good materials. Made several 1000 mile trips with no issues with lights.

This product looks exactly the same lights my Dad installed on his 1950 Chev truck. Can't wait to replace the one that was lost over the years.


They work, and they are just like the ones these replaced so they match up to the mounting location. But they are expensive for a little metal and plastic.


Great products, fair prices, excellent service. Only place I look.


Very happy with the Peterson clearance / side marker lights. Very sturdy, know they will last. I can’t wait to install them on my Magic Tilt boat trailer.


Great product and fast service. Always having problem with clearance lights being broken off trailers or simply stop working. These clearance lights are built to last and easy to install. Highly recommended.


This is a classic American product: tough, effective, and reasonably priced. They are to be replacements on a flatbed I am installing on another truck. So that they fit is definitely a bonus.
Yet I'm looking also to increase efficiency with LED bulb equivalents. This is not easy to do because most of these fixtures have bulbs so well shock mounted and with bulbs that last so long replacements are not a priority. eTrailer did a fine job of putting me in touch with people at Peterson who can provide the necessary specifications.
Shipping was fast. Packaging was fine. No complaints.


Finally located these truck marker lights for sale at I have used the Peterson Side Marker Lights, 119A and R for over thirty years on my farm truck. The metal housing finally rusted, but all lights still work!!


This product is an exact match to the ones on my 1966 Kencraft travel trailer...I couldn't be happier. I will be changing the four running lights on my other 1966 Kencraft trailer as well. Thanks for the prompt service and a great product.


Appears to be very solid in quality made


Quality product.
I avoid other sites
direct. Hope as much of your products as possible are made in USA.


These are just what I wanted for my customers trailer. He is very pleased with the products and can't wait for me to get it all together so he can start using the trailer. What was on there before was total junk. Half worked and half didn't.
Great company!


This was the exact lamp my customer requested, and thank you very much.
The easy to navigate you website and the expedient delivery as nothing less than awesome yet again!

My business with you will continue as well!




It is very sturdy and will hold up better than original lites.


Work Great.



Rec'd. everything and now to install! Thanks again!



Great product for the price. The shipping was very fast.

  • Replacement Armored Lights with 3-1/8" Mounting Hole Centers
    I believe the Peterson Armored Clearance and Side Marker Trailer Lights # 424000 (Amber) and # 424200 (Red) are what you are looking for. When measured at a diagonal the mounting holes are 3-3/8" apart on center, but when you measure them in a straight line they are right at 3-1/8" (see attached). I have also linked some review videos for you to check out. If you have something else please let me know and I can see if we have anything else for you.

  • Watts of Peterson Steel Armored Clearance and Side Marker Light
    I contacted the manufacturer, Peterson, who told me the Peterson Steel Armored Clearance and Side Marker Light - Amber # 424000 is 4.9 watts. This same light is also available in red at part # 424200. I have added links to video reviews of both lights for you to check out.

  • Armored LED Clearance Light # 424000 Recommendation for a 2007 Jumping Jack Trailer
    The reason some lights have two wires and others only have one wire is because some lights ground through the mounting studs (one wire lights) while other lights have two wires, a power wire and a ground wire. If your old lights were one wire lights and you wanted to use a Square LED Trailer Clearance, part # MCL36AB, you could run the ground wire to the mounting stud for the light and you would be good to go. We do not sell rock guards for the # MCL36AB, but we do sell armored clearance...
