Features to know about

Brighter Light with Less Power: 5-Diode LED Efficiency

This Piranha LED clearance and side marker light delivers strong, even brightness while pulling just 0.14 amps at 12V. The five red diodes create a clean, vibrant output that’s easier to see than older incandescent bulbs, yet it uses less power. With an operating range of 9V–16V and a life rating of up to 100,000 hours, you can count on consistent performance without worrying about bulb changes or dimming over time.

Better Visibility from All Angles: PC-Rated 180-Degree Coverage

Visibility matters when you’re on the road, and this light’s PC rating ensures you’re seen from both the front and sides. It produces a 180-degree beam pattern, meaning it works as both a clearance light and a side marker when properly mounted. That wide spread helps other drivers notice your trailer sooner—an easy safety upgrade that makes night towing more confident.

Clean Look with a Recessed Mount Design

The 2-1/2" round shape tucks neatly into place using a recessed grommet mount, so the light sits flush instead of sticking out. It’s perfect for applications where you want a smooth finish or need to replace an existing flush-fit light. The AMP-style plug connection keeps moisture out and wiring simple, while the durable plastic base and acrylic lens hold up against wear and weather.

Modern Design, Long-Term Reliability

Part of Peterson’s Piranha series, this light pairs modern style with rugged build quality. The sealed LED design means no bulbs to replace and no fragile filaments to break. Once installed with the proper grommet and plug, it’s a reliable upgrade that stays bright and solid through years of use.

Video Transcript for Review of Peterson Trailer Lights - Piranha Red Lens LED Trailer Clearance Side Marker - PE66NR

Hi, everybody. Andy here with etrailer. Let's take a quick look at this Piranha red lens LED trailer clearance and side marker light. Now this 2 1/2-inch round trailer light from the Piranha series is going to serve double duty for you as both a clearance and side marker light when properly mounted. This is designed with a modern touch and a vibrant illumination. So it's gonna bring a stylish yet functional upgrade to your trailer.

Obviously, I have this connected to my power source already. I do want to point out that this pigtail is not included. This is a pigtail that I'm supplying here, so I can power this up. So just be aware that you are just going to get this light. Now this light does use efficient red LEDs housed behind a durable red acrylic lens and plastic base.

And as you probably know, LEDs are a smart replacement for traditional incandescent bulbs. They shine brighter, they draw less power, and they're gonna last up to 100,000 hours without the worry of brittle filaments or bulb replacements. So, ticking my studio lights back on here, I just kind of wanted to give you a good idea of just how bright this was in low light or dark conditions. Just wanted to give you some other pieces of information about this light. The recess mount is going to install easily with a grommet, and the grommet is sold separately.

And this is going to connect via an amp-style plug, giving you a secure weather-resistant fit. It is PC-rated, meaning that it delivers a 180-degree beam pattern for excellent visibility from multiple angles. This is built for your 12-volt DC systems. And again, giving you that measurement here at that diameter first, as you can see, 2 1/2 inches. And then in regards to the thickness, looking at just the light itself, pretty close to an inch, but if you're including the plug as well, closer to 1 1/2 inches.

It does contain five diodes. It's gonna give you a strong, even output as you've already seen. But if you do have any other questions, whether it's about this light or anything else that we have here at etrailer, don't hesitate to reach out, 'cause ultimately we wanna make sure that you're getting exactly what you need. Well, again, my name is Andy. Thank you for joining me.

Perfect fit and a higher quality product.

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.

Great price, fast shipping cant ask for better
by:
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.

I installed these lamps and my daughter’s 2012 Thor RV to replace the outdated and faded incandescent lights. They were amazing from the start. I get nothing but compliments on how bright and clear they are along with how easy they are to see. I’d recommend them to anyone with old style lamps on their trailer or RV.
by:
Quality is great. They were a perfect match and fit for my Felling trailer.
by:
Exact replacement for my trailer. The factory incandescent bulbs had faded and connections were failing. With a quick inspection with a multi meter I found that all the lamp bases checked out.
I installed this Amber and Red marker lamps through out the whole trailer. I now “glow” going down the road at night. I highly recommend these replacement lamps.
by:
Not sure its anyones fault but the LED marker lights on my trailer fasten to the wall with screws and today that style is not made as it was in 2017...So i am rating the lights "average" cause till i open the light up without busting it I got to make it work and your lights are just the same as the rest...lights look fine and i will let you know how it works out...

  • Looking For A Rubber Grommet For The Peterson PE66NR Round Light
    Hey Brian, If you are looking for the grommet for the light # PE66NR, we have them already together as part # PE46NR. This is the light with the grommet kitted together. For that 2 1/2" Peterson light, we do not have the specific grommet for it as a separate part available, just the light and grommet together. Do you already have the lights you are using as replacements and just need the grommet?
