Optronics MC67 Series Amber Sealed Marker Clearance Trailer Light Dimensions

Sonically Sealed, Waterproof Trailer Light

The waterproof construction of this light makes it ideal for use on trailers that may be submerged, like a boat trailer. The housing and lens are sonically sealed together to create a single unit, which means that water will not get into the light and damage the diodes or circuit board.

PC-Rated Lights

Diagram of light spread for PC rated light

A PC-rated light produces a 90-degree angle of light to either side of its centerline for a total of 180 degrees of coverage. This beam pattern can be clearly seen when you are standing directly in front of the light, as well as when you are standing on either side of the light. When properly installed, this type of light can function as both a front clearance light and a side marker light or as a rear clearance light and side marker light.

it's been a year with these blubs, still going strong
etrailer has excellent people, service and products!


Knowing that a Black trailer would be hard to see at night the following lights were added to my custom built trailer for night time safety.

1- Side mount red and yellow fender light which only works when either the brakes or turn signal are in use.

2- Front Clearance lights, which give additional lighting at night when approaching on coming vehicles.


Received everything I asked for pack nicely in a box


Excellent service, speedy delivery and perfect look and fit as original. Advised of order placement and shipping status. This is the third order I have placed and each has been clean and easy. I will continue to do business with etrailer in the future.

I bought these incandescent for my leeisurelite trailer so i could stop hyperflashing. My trailer worked o k on 2014 limited but not 2017 cvo limited. When u have a cvo the bcm is totally different. Badlands and custom dynamic don't have a load equilizer for cvo. I put these lights on the front of my trailer and didn't have a problem. I couldn't put a Universal 5.6 Ohm Turn Signal Load Equalizer for Harley-Davidson® because they heat up. I couldn't put it inside the trailer (heat)or the outside because not waterproof. The incandescent lights work. Cheap and the easiest fix. I also had a isolator harness.

O K no problems


My Jetski trailer had a clearance light that was knocked off before I bought it. It's always bothered me and I finally bought this one to replace original, no longer available. It fit fine and covered existing holes. I had to drill a hole in the frame behind the light to allow the two pins to enter the frame itself and connect to existing wiring. I bought two in case I decide to change out the other one on the other side of trailer so they match but, since you can't see both at the same time, I'm OK with it for now. Looks good.

My new LED light is still functioning. Looks good. I still havent replaced the old incandescent one on other side


I have ordered from etrailer a few times and I always receive my order promptly and correctly. Thank you etrailer!!!!


These are a direct replacement for my haulmark car trailer. The lights work great and I decided to order an extra set and a mounting bracket in case one breaks while on the road. Just take your time when replacing the lights to avoid breaking the retaining clips.


Nice quality! Works well!


Exactement ce que je recherchais, remplace exactement les originales
[Exactly what I was looking for, exactly replaces the originals]


This trailer light bulb fits my existing Peterson 154A trailer light. And shipping from etrailer was fast, convenient and cheap.

It F.


Products are still functioning. It is incandescent, so it matches my other lights in brightness and looks.


Ordered this item on a Tuesday and by the following Monday I had it. Was anxiously awaiting it to arrive. Because I needed it ASAP to repair my trailer clearance lights so I could cover my trailer for the winter. I tried getting this item from the dealer (who I found out was no longer in business) and I also tried getting it from the trailer manufacturer. It took the manufacturer almost a week to get back with me. With a price that was much higher than Sorry, didn't have time to take any pictures; had to cover the trailer up with a RV Trailer Cover before bad weather.


Poles are 1/32 to long.wont fit


Well you would think that trailer lights would be pretty common in most stores. NOT! Especially the half lights of red/amber running lights.
When I found etrailer on the net it was a refresher to see so many lights and to actually have the ones I needed.
Kudos to etrailer. Will be shopping with you folks from now on with any of my trailer light needs.


Like other reviews have said, I also found the side marker lights very easy to install. The only problem? They're brighter than every other light on my 1983 Coleman Columbia camper. I'm thinking about replacing the rest with e-trailer lights! And the service was first-rate... Not always the case with e-commerce outfits.


Great price. Fast service. My go to place for trailer lights!



Still great!


Everything is good except 3 of the Amber led marker lights went out after about 4 months.
Had to replace them.


Perfect fit, good price


All items arrived quickly and in good condition. Items needed to replace marker lights on a Haulmark trailer I own, old lights still worked but lenses had faded after years of sitting in direct sunlight
If newer LEDs would have fit old style holders I would have changed over to them but they are different size. Got yellow, red and half yellow-red. Good product.



Ordered for my boat trailer.Purchased lights both last
year and this year.No compaints,Fit good and can;t beat
the price.

I chose these ("Opttronics")marker lights, because they give off bright, even light, without a huge power draw. I am installing them on a customized electric adult trike, using them as extra turn signals on the lower front portion of the rear fenders (unable to provide pictures at the moment) for added safety, because they will shine out toward the sides as well as forward. =o)


This part was a perfect replacement for the one that was all sun faded. Plugged directly in & worked perfectly!
The best!



All of the products are still working like new Great products Will order from you again next time I need something


We were delighted to have received our lights. However we over looked that they did not come with the mounting brackets. Would you be able to help or point me in the right direction.


The running lights I ordered for my trailer snapped right into place. I placed the order and it was filled that day and sent out to my address also Etrailer helped me with the shipping cost. Will definitely order from them again. Best of all they beat everyone else's price.


Perfect fit, No more white fades marker lights.

Jack B.


Just like it should.

  • Replacement Lens And Bulbs For Clearance Lights On 2006 Pace Journey Trailer
    To find the right replacement lens and bulbs for your 2006 Pace Journey, we will need to know what lights you have. You will want to take the lens off and check the housing of the light itself. The numbers on the lens will not be for the light. Many times you can find the number for the light on the back of the light itself. If you are unable to find the model and manufacturer of the lights, you can take some measurements of the lens and let me know what they are and I can try to find...

  • Clearance Light Recommendation that are 3-7/8 inch x 1-1/4 inch x 7/8 inch
    I believe the Clearance Light part # MC65RB would be the correct light for you. The difference in length is about .1 of an inch which would be close enough. Especially since these look exactly like what you have and the other dimensions match up. The amber version of this is part # MC65AB. Fort the amber/red version you would want # MC65ARB.

  • Replacement Trucklite 7318 Light Options
    We have several trailer lights that could potentially work for your trailer, but not the specific one you are looking for. I did an online search for Trucklite 7318 and was able to find a website that offered what looked like the correct part you would need. I wasn't able to get any pictures of it so it would be hard for me to determine what would be the closest thing we offer that would potentially work. I did attach a link to a page that has all of the trailer lights we do offer. Most...

  • Will Optronics Clearance and Side Marker Light # MC65AB Replace a Light Marked SAEP2P3PC29T
    To order trailer lights you will want to order by part number on your lights or by the size of the light you will need. The SAE stands for the Society of Automotive Engineers. The SAE part number is not the part number of the light, it is just a number on the lens that means that lens has passed SAE guidelines. These part numbers are usually on the lenses of most all trailer lights. You will want to get a brand name (Bargman, Peterson, Wesbar) and the part number (40-38-001, 154R, 221902)...

  • Can the Clearance Light MC65AB be Wired to a Trailer that Uses a Ground Wire
    To install the part # MC65AB you would want to use the bracket with wiring part # A65PB which has a power wire but then grounds through the mounting hardware. If you have a ground wire on your current fender setup you can run the ground wire to the mounting hardware and be ready to go.

  • Replacement Trailer Clearance Lights for Bargman 99 Series
    The correct replacement trailer clearance light for a Bargman 99 Series is the Optronics Trailer Clearance or Side Marker Light part # MC44RB for red or part # MC44AB or amber. The mounting holes for this light are spaced 3" apart on center. It features a simple two wire installation, one for power and one for ground. In order to remove the old lights it would be easiest to just drill out the rivets with a small drill bit. The drilled holes would then make good pilots for the self tapping...

  • Can Incandescent and LED Bulbs Be Mixed To Stop Hyper-Flashing
    If you were to install the Optronics Incandescent Trailer Clearance and Side Marker Light part # MC65AB inline with the stop/turn signal lights on your trailer that could then allow the system to draw enough power to stop the hyper-flash but there would be no way for me to confirm this, you would just need to give it a try. Also, this is a single function light so it would blink with the turn signals and then stay illuminated when the brakes are depressed. If you can confirm the trailer...

  • Is Sealed, Thin Line Two-Bulb Trailer Clearance, Side Marker Light Available as an LED
    Yes, there is an LED version. You will need the Thin Line LED Trailer Light, # MCL65AB. I have included a link to a video review of this light for you. To mount the light, you will also need a bracket like # A65PB for black or # A67CB for chrome.

  • Power Draw of Optronics Trailer Clearance/ Marker Light # MC65AB
    According to my Optronics representative, the Optronics Sealed Trailer Clearance and Marker Light, part # MC65AB draws a total of 0.6 amps at 12.8-volts. An LED version is also available, part # MCL75AB which draws a fraction of that, 0.06 amps at 12.8-volts. Either lamp is used with a base, part # A65PB in black or # A67CB in chrome plated plastic. The lamp base has a single power wire, and picks up its grounding connection by its mounting hardware being connected directly to the trailer frame.

  • Is A Mounting Bracket And Wiring Needed For The Optronics Trailer Light # MC65AB
    The Optronics Trailer Light, part # MC65AB, will need a mounting bracket and single wire plug like the Optronics Black Bracket and Single Wire Plug, part # A65PB. The trailer light will not mount directly to the trailer without a mounting bracket. The # MC65AB trailer light does not have any wiring. When this light is mounted to the # A65B mounting bracket it will ground through the mounting hardware and the single wire plug on the bracket will be used for the power lead. I also have...

They are Optronics # A65PBPG, # A65PB and # A65B. The first two come with a single wire, the differentiating factor is the # A65PBPG comes with a plug-n-go male connector whereas the # A65PB is intended to be hardwired. The third one, # A65B is the bracket without the wires. If you would rather have a chrome colored plastic bracket, Optronics...

  • Trailer Jack Caster Wheel and Adding Turn Signals and/or Marker Lights to Trailer Fenders
    Caster wheel # BD500245 could potentially fit your current jack. It is designed to fit 2 inch diameter jack tubes. The wheel is rated for 1,200 pounds so if the jack is rated higher you will still be limited to 1,200 pounds. Trailers in the US have combined brake lights and turn signals. If you want to have separate amber turn signals on the fenders then that will require some additional parts. The left turn/brake light wire on the trailer connector will need to be split with one of the...
