P2-Rated Lights
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.

I replaced a red LED marker light on my RV a year ago. The original leaked water and failed after about 4 years. It was easy to swap out. It is still dry inside and functions fine.

Work great on my motorhome.

Easy install and bright marker light. I also used two on the top back side of my horse trailer as an extra turn signal and brake light. My existing turn signal and brake lights were really low on the trailer and these helped it become more visible when I was slowing down or turning.

I used this side marker to replace existing Bargman 99 series lights on a camping trailer. The Optronics LED model was not quite as bright as I would expect for a 6 diode unit, but still an improvement over the incandescent model. It is larger in size than the Bargman 99 series, so it covers up any surface imperfections on the trailer.

These lights were used to replace the incandescent versions and they worked great.

Look great don’t tho k they will work on boat trailer not water proof
by: John G.09/15/2013
A good light, but there are issues.The LED's emit a yellow light, not white. While the lens is red, it gives the light is almost an umber color and not quite as intense. The potential for a discussion on the color when lit is there. The mounting holes are positioned too close to the center LED compartment to accept hex hex head tapping screws. It's do able but difficult. The light itself is well made with all components includind the 20 guage aluminum wire encased in resin.

It turns out that the lens had been switched on the light base. The proper base has red LEDs not yellow with a red lens. When paired properly, a bright red light is emitted.

Great job, right part, delivered on tim e.
by: David10/22/2018
These lights are just what was needed to replace old incandescent lights on a small camping trailer pulled behind a motorcycle. These are bright so as to be seen better by others because motorcycles are sometimes more difficult to see compared to larger vehicles and the LED lights are easer on the motorcycles electrical system. Shipping was prompted, the product is as described by etrailer and arrived in good condition.
by: Jim B.05/14/2013
Great product fast shipping. with the two wires I could mount them on fiberglass with no worries.
Thanks e trailer, great job. lights work great and are very bright...

Lights are great, super bright and no corrosion issues. Exactly as described, great price and great service and shipping.
by: Douglas 12/04/2022
These are good but I was hoping for more space on the back side to bring the wires through the pre-existing hole in my trailer.
by: Russ T.04/11/2017
LED lights are the way to go. The reflective marker lights are great for times when the lights aren't on yet headlights will reflect off them letting the driver know there is something there. The only thing would be better on these lights would be a better ground.
by: Mac03/23/2016
I ordered some of these previously after a few years of fighting with incandescent bulbs in the trailer marker lights. These LED units are much brighter and will last many times longer than the incandescent units. In my initial order, I had somehow managed to miscount how many I needed, so this order is to replace the last few of the old style markers & bulbs still remaining.
by: Bob KECG05/28/2017
Installed in old light position without a problem. One issue - polarity was not an issue with the old lights but is an issue with the LED'S.

These lights are great. Easy to install and bright.
by: James06/17/2022
Easy to install. Great replacement option for my old lights on my camper. I was surprised that the LED bulbs are red along with the lens.
by: Kevin04/03/2017
These lights are an excellent upgrade for my pop-up camper. I highly recommend them over incandescents for replacement of old faded marker lights.
by: Guy C.09/29/2015
Exact fit! Makes a big difference to a trailer with some age on it. I would highly recommend making the change to the LED lights, the current draw is a lot less and these lamps are bright and clear.
by: Aaron02/13/2017
Rewired my stock trailer and replaced all the lights with LED. Works and looks great!
by: Jason12/13/2010
Good upgrade over conventional incandescentI looked to upgrade to LED marker lights on a travel trailer after experiencing corrosion issues in the sockets of traditional incandescent marker lights. These LED lights are a good upgrade over the OEM lighs.
by: Patrick12/10/2018
These are good lights with pretty secure covers. They work great and bolt up exactly where the old ones did. The only issue I saw was that the wires can easily get pinched when mounting these on a surface with a center hole. These seem to be designed for the wires to be routed out of the side or bottom of the light, not the back. No biggie though.
by: ConnerCattleCompany08/11/2016
Good clearance light. Gives off plenty of light at night and in low light situations. etrailer.com has great customer service and will take care of you.
by: Keith07/12/2017
I installed the lights at full sun. And they are still bright.

- Replacement Clearance Lights for 2001 Dutchmen Travel TrailerIt looks like you are needing replacement red clearance lights for the rear of your 2001 Dutchmen Travel Trailer. In order to choose replacement assemblies, I recommend taking a couple measurements on your existing units. Based on the picture you provided, something like the Optronics LED Trailer Clearance, Side Marker Light # MCL31RB might be an excellent replacement. This red, LED clearance light measures 4 inches long, 2-1/16 inches wide and 1 inch deep. It features a 2-wire design...

view full answer... - Replacement Red Trailer Marker Light for 2013 Trailer Star Boat TrailerI was not able to find specs for the marker lights supplied on your Trailer Star boat trailer but I was able to find several photos that show the red oval grommet-mount lights you refer to. There may be a part reference number on the back of the light housing; often this is printed rather than molded into the part. If you can find a part number you can search our site using that, but if its not available you can take a measurement of the actual opening (not the grommet, but the opening...
view full answer... - Can Additional Turn Signals Be Installed on the Sides of a TrailerAs far as turn signals go; that we are aware of there are no restrictions that would prevent you from installing an additional blinker on the side of your trailer in red or amber. You would need to consult your local DOT for more info, but I would be surprised if there were restrictions that would prevent that. Especially since semi-truck trailers often have them. The easiest way to do this would be to use red lights since you could simply tap into the stop/turn circuit on either side...

We do not have an exact replacement for this light but we do have something very close in the Oval LED Trailer Clearance Light part # MCL31RB for red lens and part # MCL31AB for amber lens.

The other wire will be connected to the appropriate wiring on your trailer that your old lights were hooked...

This is a very nice, LED amber light that measures 4 inches long, 2-1/16 inches wide, and 1 inch deep. It features a two-wire design and a white base surface that mounts on 3 inch centers. I recommend comparing these dimensions to your existing lights to ensure they will work as replacements....

- LED Replacements for Optronics Rectangular Trailer Clearance Lamp MC32RBWe do not have an exact LED replacement for the incandescent side marker lamp you mentioned, part # MC32RB, but we have an alternative that is very close. Part # MCL31RB (red lens) and part # MCL31AB (amber lens) are shaped a bit differently than the lamp you referenced. They are also about an 1/8 of an inch wider and thinner in depth. The important dimension, the distance between the mounting holes, is still three inches, so you will be able to use the existing holes. If you click on...
view full answer... - Installing Side Trailer Lights to Function as Turn Signals You can certainly install some additional lights on the side of your trailer to function as another turn signal. You can use a red LED light like the Optronics Oval # MCL31RB for this purpose and simply tap into the stop/turn circuit on either side of the trailer. Keep in mind that if your trailer has combined brake and turn signals (which most do), the lights will activate when the brakes are applied as well. If you want to separate the functions out so that they only illuminate with...
view full answer... - Mounting Instructions for Optronics # MCL31RB LED Clearance/Marker Lights I'm assuming that you're speaking of the Optronics # MCL31RB side marker/clearance lamps. These lamps are designed to surface mount using machine or self tapping screws as shown in the photo I've provided for you. A gasket isn't available, but using a thin bead of # 0160297 silicone to prevent water from getting behind the lamp would be an excellent idea.

- Availability of a Oval Trailer Clearance Light with a Black BaseThe closest thing we have to a version of the Oval LED Trailer Clearance, Side Marker Light # MCL31RB that you referenced with a black base in an amber and red lens would be the Red Oblong Trailer Clearance, Side Marker Light # MC31RB and the Amber Oblong Trailer Clearance, Side Marker Light # MC31AB. Both these lights have black bases, but they have incandescent bulbs instead of LEDs.
view full answer... - Replacement Red and Amber Lens for Clearance Light MCL31RBYes, the replacement lens you would want for your # MCL31RB is the part # A31RB. And the amber version is part # A31AB.

view full answer... - Is a Deeper Lens Available for the Optronics MC32 Series Clearance Light to Install LEDsWe do not have a deeper lens for the Optronics MC32 series clearance lights, however we do have similar LED clearance lights that you may be interested in. Check out the Optronics LED Clearance Light, # MCL45RB or # MCL31RB. These lights have almost identical dimensions as the MC32 lights and will use the same mounting holes on the trailer.

Other similar lights include LED model # MCL31RB and incandescent model # MC32RB. Trailer makers do not maintain specs for smaller items like lights so just check your overall light size and mounting hole spacing...

- Does Optronics # MC66RB Incandescent Trailer Clearance/ Side Market Lamp Include BulbsThe Optronics # MC66RB Trailer Clearance/Side Marker Light does indeed include bulbs. Optronics also offers a similar LED lamp, part # MCL31RB. LED lamps draw a fraction of the power of incandescent bulbs, and will last considerably longer.

2-year update: The LED marker light is still dry and continues to function fine. I will definitely buy it again if needed for another location on my RV.
