Optronics MC48 Series Amber Marker Clearance Light with Reflex 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 Optronics Trailer Lights - Clearance Lights - MC48AB Review

Today we're going to be taking a look at the Optronics rectangular trailer clearance or side marker light. This amber light is reflectorized so it has a built in reflector meaning that a separate reflector is not needed for a Department of Transportation compliance. It's a molded plastic housing with a durable lens. It's going to provide all weather protection against corrosion. That lens is an acrylic lens, and then the housing is an ABS plastic construction. The light features a flush mount design. It's going to be mounted using two screws.

Mounting hardware's not included. It also comes with an easy to replace incandescent bulb that's going to use bulb number 194. If we take a measurement of the distance we have between our mount holes on center, it's going to measure 3 3/8". Again, mounting hardware's not included. It's a two wire design, so black wire is for power.

White wire is your ground wire. It's also going to come with this foam pad right here. It's going to offer a really nice tight seal at the mounting location along with a little bit of padding. Taking a look at the overall measurements, starting with the overall length. The outer edge is actually at the back of the light, so that's going to give us a measurement of about 3 7/8 to 3 15/16" long. Going this direction, edge to edge is about 1 7/8", and then the depth.

If we just measure this area right here, that's going to give us a depth of about 1/2". Nice low profile light. Now, at the mounting location it does require 1 1/4" diameter hole for a flush mount installation. That hole is needed for this area right here to fit into. Then when it comes to the power draw, at 12.8 volts, we're looking at 0.2 amps. We're going to go ahead and hook it up to power.

That way you can see what it looks like with some power running to it. We'll also be able to turn off our overhead lights so you can see it in a low light setting. Again, our black wire is our power wire. Then our white wire is our ground wire. So you can see here that it sends out a really nice consistent signal. Again, it's going to contain one incandescent bulb. It's got that reflectorized lens with the reflector built in. That does have a clear opening right there to allow plenty of light to come through that lens. That's going to do it for today's look at the Optronics amber rectangular trailer clearance or side marker light.

This was the perfect place to find this marker light. I searched numerous stores for the light assembly and was unable to find a replacement for my broken one on my older RV. The shipping of the item was faster than anticipated and I had it in a couple days. I'd highly recommend etrailer to my friends if they were in search of similar items. 695332

Perfect fit for my side marker lights on a 2007 Fleetwood Terra LX. Had to buy my own stainless steel screws to replace the old rusted out screws. Would’ve been a 5 Star review if it came with new screws too. Great help from Nikki in Customer Service to locate which part I needed. Thanks, Larry - Shanty Shakers- Escapees 587908

This item was the perfect replacement for a running light on my 1989 Yukon Wilderness travel trailer. My complaint is that, there were no mounting screws provided. Seeing as the screws for the light being replaced were almost completely rotted away, I had to go out, and purchase new ones. Kind of inconvenient, considering the closest hardware store to my house, is half an hour away. I'm not sure if I missed the statement in the description, that it comes with screws, or not. The light was not in a sealed package, so maybe they were forgotten? 583475


Comments

Unfortunately, Optronics does not include mounting hardware with many of their lamps because they can be mounted in many different locations and to many different surfaces. The correct mounting hardware would depend on the surface the lamp is being mounted to. I apologize for the inconvenience, and Ill have the fact that the hardware is not included added to the product description.
