Features to know about
Brighter and Dependable Illumination: 2" Incandescent Clearance and Side Marker Light
This round 2" Peterson trailer light uses a premium incandescent bulb that delivers up to 15,000 hours of life. It’s built to work as both a clearance and side marker light when properly mounted, giving you dependable brightness and coverage. Designed for 12V DC systems, it provides clear amber illumination that helps other drivers see your trailer from multiple angles.
Built to Handle Wet Conditions: Sealed and Waterproof Housing
If your trailer ends up in rain or water spray, this light is made to stay sealed and dry inside. The housing and lens form a single waterproof unit, keeping out moisture that can corrode contacts or shorten bulb life. That dependable sealing makes it ideal for use on trailers exposed to harsh outdoor conditions or occasional submersion.
Wide Safety Coverage: PC-Rated 180-Degree Beam Spread
With its PC rating, this light produces a 90-degree beam angle to either side of its centerline for a total of 180 degrees of visibility. When mounted correctly, it can serve as both a clearance and side marker light—so your trailer stays visible from the front or rear and from the side. That wide spread of light adds extra safety during night driving or low-light conditions.
Straightforward Mounting: Recessed Installation with Standard 2-Prong Plug
Installing this light is simple. It uses a recessed mount with a black PVC grommet (part #146-18, sold separately) and connects using an industry-standard 2-prong plug (part #142-49, sold separately). If you’re replacing an existing light, you can use the same hole. It’s designed for easy integration with no special adapters needed.
Proven Compatibility: Direct Replacement for Popular Brands
This Peterson model works as an exact replacement for Truck-Lite #30200Y, Grote #45823, Optronics #MC53AB, and Primatronics #PT3000A. That means you can swap it in without guesswork, keeping your lighting system consistent and reliable.

Video Transcript for Complete Breakdown of the Peterson Clearance and Side Marker Trailer Light
Today we're gonna take a look at the Peterson Clearance Side Marker Light. This is going to be a two inch round amber light. This is going to function as both our clearance light and side marker light, since it is PC rated. That means that it's going to give us that combined clearance and side marker function, since it can be seen at 180 degrees.It's going to have a recessed mount with a black PVC grommet that is sold separately, you can find that here at etrailer.com using part number 146-18 and that will look like this. So whenever you put that in place, it's going to kind of finish the look of our light and also provide a little shock absorption on the back, or for our light itself. So that would be what it looks like with the grommet.
Again, that does have to be purchased separately.Another thing you can pick up is an industry standard two prong plug, you can also find those here at etrailer.com. We plug that in the back, you'll be able to see our light turn on and we have two different styles of this two prong plug. There's the 142-49 or the B142-50. And again, both of those can be found here at etrailer.com, so you can get all your lighting functions wired up. And if we turn it on, we'll have our side marker light come on, just so you can get an idea of how bring that's going to be.
It's going to give us a nice clear light, clearly visible from that 180 degree angle. It does come with the bulb, it's going to have a 15,000 hour long life. So it should be long lasting bulb, shouldn't have to replace it any time soon.As far as the dimensions with our light, go over those here, if we unplug our wiring here. It's going to be about two inches in diameter and it's gonna sit about seven eighths of an inch deep. This does have a one year limited warranty from Peterson and it is a made in USA product.
And that's gonna do it for our look at the Peterson Clearance and Side Marker Light for two inch round with an amber lens.

Side marker trailer light is an exact replacement (same brand and model number as original) for my 20 year old snowmobile trailer. A few dollars more than I hoped to spend but it's made in the USA. Combined with a few other items it qualified for free shipping.
