Older incandescent lights can draw more power and burn out quickly, but this Peterson Piranha LED uses two efficient diodes that deliver bright, clean light while only drawing 0.03 amps at 12V. With an input range of 9V–16V DC, it runs cool, stays reliable, and lasts up to 50 times longer than traditional bulbs. No fragile filaments or bulb replacements—just consistent light every time you flip the switch.
Water intrusion is one of the fastest ways to kill a trailer light, but this one is built to handle it. The housing and lens are fully epoxy-sealed into a single waterproof unit that protects the LED circuit board from moisture and corrosion. Whether exposed to rain, road spray, or full submersion, the sealed design keeps everything dry inside and working like it should.
Rough roads, bumps, and vibration can ruin standard lights. The Piranha’s surface-mounted diode (SMD) circuit board is designed to handle that abuse. It’s shock-resistant, spreads heat evenly, and allows for a thinner construction that still keeps everything solidly in place. That means steady performance mile after mile without flicker or failure.
Installing this light is straightforward. The rectangular housing measures 4-1/16" long by 1-1/16" wide by 15/16" thick and mounts flat against the trailer surface using a flange or bracket with a 3" center-to-center hole spacing (hardware not included). The two-wire design keeps things simple—one power lead and one ground wire with a #10 ring terminal—so you can get it mounted and lit in minutes.
This P2-rated light produces a focused 90-degree beam spread—45 degrees to either side of centerline—so it works perfectly as either a clearance light or a side marker light. It delivers strong visibility straight on without glare or wasted output, giving your trailer a crisp, finished look that stands out day or night.

Today we'll be taking a look at the Peterson Piranha LED clearance or side marker trailer light. This is a submersible light sealed with some epoxy on the back here to keep our diodes protected from any kind of water or debris from getting in there and causing any damage. You can see it's a nice thick epoxy, so we don't worry about anything getting in there and causing any issues.Wire coming out of those diodes. We'll have our black wire for power, white wire for ground. And this can be used with a bracket. It's just as a surface mount bracket that is sold separately here at Etrailer.com.
That part number is B169-18, just a little black bracket that this pops into and then it'll hold it in place and kind of finish out that backside of the light.To get this mounted up, you will need to use some hardware that is also not included with this. You have to pick some up separately, but the nice thing about this is that it is a LED lights. We don't have to worry about any kind of maintenance with this. There's no bulbs to replace, no filaments that can break, so once you install it, it pretty much is good to go.It's better able to withstand shock and vibration with a durable SMD construction of the LED circuit board, which just means that it has surface mounted diodes. And that also allows for a better distribution of heat, and also thinner construction of that diode plate, so it's going to last a lot longer.
Compatible with 12 volt DC systems. This is DOT compliant, and it's P2 rated, so that basically means that it's visible from the front but not so much from the side.So if you want to use this as a side marker light, it can't really operate as a clearance light at the same time. I'm going to connect this to my power source so you can see how bright it is. Again, black wire is going to be our power, white wire with that ring terminal already on it is our ground. That ring terminal is a number 10 ring terminal.Let's see, my light comes on there, and we have our two diodes.
Turn the light out in the studio and get a better idea of how bright that is. So not terribly bright but enough to be DOT compliant and make sure that everybody can see our trailer in low light situations. But as you can see, clearly visible from the front, you turn it to the side not quite as visible. So that's why it gets that P2 rating.Disconnect our wires and let's go over some measurements. The length of the light is about four and a 16th inch, width is about one and a 16th, and then the height is right about one inch.
The length of our wires coming off of it, it's about five, five and a half inches.The distance between our mounting holes, center to center is about three inches. The power draw at 12 volts for this light is 0.03 amps and the input output voltage is between nine volts and 16 volts DC. It comes with a 10 year limited warranty from Peterson, and that's going to do it for our look at the Peterson Piranha LED clearance or side marker trailer light.

I have not installed them yet, but they look like they will work just fine. Don’t have to worry lightbulbs getting loose.
Were exactly the same size and need for my 20’ trailer!
Perfect fit and bright just what I was looking for
Great seller/ Fast shipping AAAAA +++++
Much better connection than the original incandescent lights I replaced with these LED lights, and much brighter. Great product and fast shipping!
Just what I was looking for. Was a last minute repair before trip, order fullfilled quickly and installation was perfect in time.
Thank you
Great product
Product good quality and as described.
Good product at fair price. Would buy from again!
Works as intended . Good price for a good product. I used to replace burnt out lights on my trailer. Looks like new trailer
Just what I wanted and at a great price. I will use etrailer for all my needs in the future.
Great trailer lights... they have super fast shipping.. A+++++
Replaced poorly designed original non weathersealed lamps on my travel trailer with these LED lamps. They have 2 LEDs and a 6" pigtail for your wiring pleasure.
Product was what we wanted but they came open and were not individually packaged
Do you have a question about this Trailer Light?
