Peterson 170 Clearance Marker Light Dimensions

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.

Video Transcript for Peterson Piranha LED Trailer Light Review

Today we're going to be taking a look at, and showing you how to install, the Peterson Piranha LED clearance or side marker light with reflector. Now this is what our light looks like installed. As you can see, even in a bright room, those LED's really do shine. This is going to be a great replacement, or even a upgrade, from your traditional style incandescent light. It's going to be an upgrade because LEDs have no brittle filaments and you don't have to worry about them breaking and having to change bulbs. They're also going to last a lot longer and put off more light, all while using less power.Now, if you look at the back of the light, you can see how everything is enclosed.

We also have a stud here which is going to be used to mount the light and we do have plenty of wire to connect our ground and power wire. What's nice about the ground wire is it already has a ring terminal on the end, so if you don't want to mount it to a different location, you can simply put it over the stud and ground it that way, and then mount the light to the trailer frame. Inside of the light you can see how everything is enclosed. That'll help keep it protected from the elements. To help you determine if this light will work with your application, we're going to give you a few measurements.

From end to end it's going to be three and one eighths of an inch long. From top to bottom it's going to be two inches tall. As far as the thickness or the depth of the light it's going to be 15/16ths of an inch.Now that we went over some of the features, I'll show you just how easy it is to get this light installed. We're going to start by removing the hardware off of our stud. Now some applications may be a little bit different on where you mount it, but in our situation we already have a hole pre-drilled here to run our stud and our wiring through, so that's exactly what we're going to do.

Feed our wiring through and pull it flat against the trailer. In the back side what we're going to do is to actually take our ground wire, put it over the stud and we'll take our lock washer and finally our nut. Go ahead and run that down, then we can grab our socket just to fully tighten it. Next we can focus on hooking up our light's power wire through our trailer power wire. We're going to accomplish that by using a heat shrink butt connector.

If you need some of these you can find them on etrailer.com. We'll just slide one in over the wire, then we'll clamp it down. Then we'll grab the power wire from our trailer, put in the other end, do the same thing. Now with our heat gun we can heat up our heat shrink to make a nice seal.Now with everything connected you can pull out the slack and secure everything up out of the way so it doesn't get damaged. Now with everything hooked up we can put some power to it to make sure it's working properly. Once you've verified it's working properly and you have more than one of these lights, you can just repeat that process for the other side. And that'll do it for a look at and installation of the Peterson Piranha clearance or side marker light with reflector.

Review from a similar Piranha in Trailer Lights


Purchased these side marker lights specifically because they have two wires rather than just a positive wire and the ground attached to the mounting grommet. Lights were easy to mount and with rubber gasket they are protected from vibration.


Comments
All lights are working! Made one important change due to use in salt water. I ran all ground wires to the front of my boat trailer, so that the ground wire connections to the trailer would not be submerged when launching and retrieving my boat.

These lights were the perfect brightness, very rugged, and easy to install inside protected areas of the frame on the updated raft trailer. etrailer has great selection, the website makes it easy to find the best parts for the job, and their communication is excellent. Their videos and reviews are invaluable.

The 168R side marker light paired with the B168-18 mounting gasket were easy to mount and work perfectly.

Review from a similar Piranha in Trailer Lights


Replaced poorly designed lights on a travel trailer with these. The original lamps were not weather proof and used tensioned contacts that were prone to oxidation and corrosion from the elements. These LED lamps are sealed in epoxy so the elements will not affect them. Each lamp has two LEDs and a 6" wiring pigtail.

LIghts still working a year later

Review from a similar Piranha in Trailer Lights


Ordered 4 of your 2 1/2 inch round LED marker lights. Price was good, shipping time was good, but you placed large stickers over two of the lenses. It took a lot of effort and time to remove the goo off the lights from these stickers.


Comments
I will follow up with our Warehouse team so we can better label these lights.

I used these lights to replace the burnt out lights on the back and sides of my box trucks. These are much brighter than the originals, and as they are LED, I expect them to last much longer as well. The price was also great.


Comments
The lights are still working GREAT! Not one failure.

Small in size, but very bright. Lights were sealed well on the back and have plenty of pigtail length. Very happy with the light and price. Great value as long as they hold up over time.

3/15/2013 Item 168A - Just the right size light I was looking for to use as a side marker for a motorcycle cargo trailer. Well built product. I used with its black base (B168-18) that fit well also. LED lighting excellent. Just great to deal with etrailer folks.

Ask the Experts about this Peterson Trailer Lights

  • Is Peterson Piranha Clearance Light # M170A Submersible
    The Peterson Piranha Clearance Light # M170A is submersible and can be used on a boat trailer application. It would be an odd animal to name a light after if it wasn't submersible!

  • Can Peterson Rectangular Clearance Light # M170A Replace Square Clearance Light on Trailer
    While this light is designed as an exact replacement for a Grote #47853-5 or Optronics #MCL36AS, the Peterson # M170A will work to replace any shape or size clearance light, so it will work for you. You can mount it to your trailer using the included center stud. Alternatively, you can use two #12 screws (available at any local hardware store) to surface mount it on your trailer. I've attached an installation video for you at the bottom of the page as well.

  • Replacement Square Trailer Fender Clearance Light
    We offer tons of lights like the Peterson Piranha LED Clearance or Side Marker Light w/ Reflector # M170A which measures 3 1/8" long, 2" tall, and 15/16" deep; or the Square Trailer Clearance and Side Marker Light with Reflex Reflector # MC37AB which measures 2 7/8" long, 2 1/8" wide, and 15/16" deep, that may fit your needs. But, without measurements and some reference pictures it will be difficult to gauge what exactly you need.
