Optronics MC38 Series Incandescent Amber Marker Clearance Light 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 - MC38AB Review

Today we are going to be taking a look at Part Number MC38AB. This is Optronics Oval Amber Trailer Clearance and Side Marker Light with a built in reflector. The built in reflector is the Department of Transportation compliant so it is going to eliminate the need for a separate reflector. This is going to feature a weather and corrosion design when it comes to the lens as well as the housing unit. It is also going to feature a nice single wire design. This is going to provide your power and then it is designed to ground through the mounting hardware. Your mounting hardware is going to be sold separately.

Here on this side, you can see it has a nice metal ring on the inside. That is going to be your grounding location so again, it is going to ground through your mounting hardware and it is going to ground on this mount right here. It is a surface mount installation. If we take a measurement, the distance that we have between our mounting holes, center on center, that is going to be right on 3 inches. The overall length measuring from edge to edge is going to give us a measurement of about 4 inches long. The width from edge to edge is going to be about 2 1/16 of an inch and then the depth of the light or the thickness, measuring from the back to the front, looks to be about 1 3/16 of an inch.

This is a snap on replaceable lens as well as a replacement incandescent bulb. We are going to go and hook this up to our external power source. That way, you can see what it looks like with power running to it. You see here it sends out a really nice, clear consistent signal. It has got the amber lens so it is going to appear as an amber light and again, this light is going to function as a clearance or side marker light for your trailer. That is going to to do it for our review of Part Number MC38AB. This is the Oval Amber Trailer Clearance and Side Marker with a built in reflector from Optronics.

The product arrived fast, the online description matched perfectly to the parts received, I recommend it 679963



- MC38AB
by:

I just needed a lens but the price of the complete light assembly was just about what the replacement lens was, and not knowing if the lens would fit my base, I bought the whole assembly. Turns out the lens fit tightly on my existing base. The light is well made and I expect it to last as long , or longer, than the original. 674439

Nice light. Just like the original. 650321

by:

I was hoping they would be identical to the ones currently on our trailer but they aren't quite the same (blockier). Also, the original TT clearance lights have 2 wires coming off of the bulb socket and these only have one. They are intended (I assume) to use the screw that holds the base on as a ground connection to the trailer. That wouldn't work on our TT so I added a ground wire myself. I guess I should have seen the single wire in the picture but I missed that... 649876

The products I bought form etrailer are superior to what I replaced on my 1988 stock trailer. The clearance lights both red and amber have a good grounding and 12v supply lugs. Solid lugs for positive connections unlike the old two piece units where the ground and positive connection fails between two cheap movable parts. I'm very happy with the quality and construction of these lights. I also ordered the 3 diode ID light bar looks good and works good. On line ordering is fast and easy and delivery was three days to the west coast which is greatly appreciated thank you everyone at etrailer you do a superb job!! 543256

I appreciate the professionalism and integrity of the people at etrailer. In a recent order I placed I was delayed in thoroughly checking the contents of my order. I was still well within the 60 days. When I did look through the box I discovered I had not received an item. I'm thankful the company believed me and sent me the parts I had not received. I recommend etrailer and will shop with them again. 410528

Ask the Experts about this Optronics Trailer Lights

Do you have a question about this Trailer Light?


  • Trailer Taillight Lens Recommendation for Lights Marked SAE-AP2-79
  • So SAE numbers aren't part numbers so it's hard to pick out replacement lights based on of them since that's not info that's stored as a cross reference. We've had customers with a similar number SAE-AP2-79 which turned out to be the # 423000 for red and then for amber part # MC38AB. For just the amber lens you'd need the part # A38AB. For just the red lens you'd want the part # A38RB. If you have something totally difference send me a picture and I'll take a look to see what it might be.

  • Trailer Fender Clearance Light Recommendations
  • At this time Fulton does not offer any trailer fenders that have built in clearance lights, but one could be added to the plastic fender, # F008574, easily. We have many styles of trailer clearance lights to choose from, see link, and many are surface mount so you would only need to drill two small holes for mounting and possibly a third small hole to run the wiring through. You would also need to add a ground wire to any light you choose that may be grounded with mounting hardware through...

  • Clearance Light Recommendation for Trailer # MC38AB or # MC31AB
  • Between the clearance lights # MC38AB and # MC31AB the difference is mainly aesthetic. I personally like the black base and rounder edges of the # MC31AB so that is what I would go with. You would need to use bolts or screws to secure the base of the light to the trailer and then pop the lens on top of it to install it.

  • Replacement Amber Lens for Trailer Clearance Light Like MC38AB
  • Trailer side marker light have only that one function so this means that the two wires on your lights serve as ground and power. Some such trailer lights can have only 1 wire if they happen to use their mounting hardware to make the ground connection to the trailer. We do offer a whole range of replacement lenses for lights in all sports of shapes, colors and sizes. You can see all replacement lenses by clicking on the link provided.

  • Replacement Oval Amber Light for a Triton Trailer Frame
  • We do have a selection of oval amber light assemblies that could fit, but you will need to first find out the dimensions of the light that you mentioned to make sure you get a replacement that is compatible. You can then filter through our linked selection of oval amber light assemblies. For example; the Optronics Oval Trailer Clearance, Side Marker Light with Reflector # MC38AB matches the oval and amber description, and it measures 4" Long x 2-1/16" Wide x 1-5/32" Deep.

  • Are 4" Oval Peterson and Optronics Clearance Lights the Same Dimensions
  • They are not the exact same shape but they basically have the same dimensions with the differences being within 1/16" of each other (which could be the difference between manufacturer's preference for measurements). For the amber version of the Peterson Light # 423000 you need part # 422800 and for the red version of the Optronics Light # MC38AB you need part # MC38RB. Either way thought these lights are interchangeable with each other.
