When you want more light without loading down your wiring, this 2-1/2" round Peterson LED marker and clearance light delivers. It uses five surface-mounted diodes (SMD) that put out a bright, clean red glow while drawing minimal power on a 12V DC system. The LEDs last 50 times longer than incandescent bulbs and have no filaments to break, so you get strong illumination with no bulb changes and far less maintenance.
This light isn’t just for marking your trailer’s corners—it can also tie into the brake or turn circuits for added visibility when stopping or signaling. That auxiliary function helps other drivers see your intentions more clearly, reducing confusion and keeping your rig easier to spot in traffic or at night.
Rough roads and vibration can be tough on traditional bulbs, but the SMD circuit board design in this light keeps it steady and dependable. It’s built to handle shock and vibration while also managing heat more effectively, which helps the LEDs perform consistently over time.
Lighting angles matter for safety. This PC-rated light spreads its beam 90 degrees to either side of center for a total of 180 degrees of coverage. When properly installed, that means it can serve both as a clearance and side marker light—making your trailer more visible from multiple directions.
Getting a tidy, professional look is simple with this recessed-mount setup. It installs using a grommet (sold separately) and connects through an industry-standard 3-prong AMP-style plug. That makes wiring straightforward while keeping the face of the light neatly flush to the surface for a finished appearance.

Ellen: Hey everyone. I'm Ellen here at etrailer.com and we're going to take a quick look at the Peterson LED Clearance and Side Marker light. This is going to be a nice addition or a replacement for your lights on your trailer to maybe upgrade you from your incandescent lights, or just add on more to what you already have. Let's take a closer look at this and make sure that it's the right fit for your particular application. The main benefit of having a LED light is that it is going to be longer lasting and take less power than your typical kind of correlating incandescent bulb. At the back, it does have an attachment point for your amp style connector.
It does not come with one, but you can find a lot of options here at etrailer.com. That connector should look something like this, just a little plug that goes in there and snaps into place.You can see that it has this FIC grommet or a little rubber piece that just helps to protect it from any kind of water getting in there and causing any issues. Once you're plugged in, that just goes to our wire connections. I'm going to match all these color for color. We've got our ground connection, 12 volt power, and also have our braking function.
If you hit the brakes or hit your turn signal, it will come on and illuminate a bit brighter than before.Again, this wiring does not come with it, but it is a related part on the product page. You can pick that up while you're here to make wiring this up pretty easy and straightforward. I want to connect that up again to show you how bright that light is in the dark. Let's do that and now you can see we have those five LEDs, 4 around the outside and the 1 in the center that really illuminates. It gives you a better idea of how bright that is in the dark.As far as the size, this does work with a two and a half inch diameter hole.
It is a two and a half inch diameter light. You'd also get a recessed mount with grommet, that is also sold separately here at etrailer.com, if you wanted to clean up the edge of that so it's not just this light sitting on top of your trailer, and makes it pretty easy to plug up a larger sized hole. That related part can be found on the product page here at etrailer.com. The operating voltage for this is between 9 volts and 16 volts. It is covered by a 10 year limited warranty and it is made in the USA.
That pretty much does it for our look at the Petersen LED Clearance and Trailer light. I hope this video has been helpful. Thanks for watching.
