Optronics MC44 Series Incandescent 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.

After searching my local area for these Marker Lights a shop gave me the information about this site. It was my lucky day! It was so easy to order and the product came within the week. They are exactly what we needed. I would recommend ordering from etrailer there service is great and it saves time and miles trying to find it any other way.

I replaced the original side lights on a 2000 Casita camper and they were a nice fit. The mounting holes were the same spacing and diameter so no additional modifications were needed.

The light was a great replacement for the OEM light that had a broken wire. Perfect fit and took about 5 minutes to replace, including installing weatherproof connectors that needed heating to seal. I would purchase again.


Comments
The product continues to perform as expected with no problems whatsoever.

I looked all around for these replacement lenses. Could not locate. Was told by trailer retailer that they were old model side markers. They advised to contact you guys. Description was accurate and i was expecting to receive lenses only, for the money.. Was shocked that base ,socket and bulb were included.. Great price.. Ordering was a snap and speed of delivery was great!



- MC44RB
by:

The item is almost identical to my failed one. The failed marker only required a hot line as the ground was completed by screwing the old marker to the body of the trailer. With the new marker there is no metal plate between the bulb and the screw that connects to the trailer. To complete the ground, I took the black ground lead on the new marker, snipped it, and added a small terminal connector that will complete the ground when the marker is screwed to the trailer.


Comments
Lights are well made and continue to work, the LEDs are the key to why their so good.

I bought these to replace some damaged Glo-Brite lights on my RV. Quality appears to be at least as good as those and for the money I am very happy with my purchase. Only issue was the wires exited the light base in a different location and I had to drill new exit holes to use the existing wiring hole in the RV, but this was easily done.

Good quality. I have recently changed out all of the side marker lights on my RV, red and amber, etrailer products are a better quality then the original ones. Very happy!

I was looking for an exact replacement light for one I broke on my camping trailer. Etrailer had them at a great price. I ordered extra in both red and amber so will have spares when I back into something else. Great company to deal with. I was so glad to find the exact light to match what I had. Couldn't be happier.


Comments
Both products have worked out beautifully. Thanks for the follow up. E Trailer is a great company to deal with.

I purchased 2 trailer lights as replacements for my Glo Brite 117R side marker light that was missing its red lens. It fit perfectly. Excellent service! Fast shipping. I definitely recommend.

The marker light was an exact match for our 1996 Winnebago Suncruiser. Shipping was really fast! We are very pleased with the product.



- MC44RB
by:

The units came in as expected. They look like direct replacements to the original units.

Came in a timely manner and worked perfectly fine to replace the lights that broke on our trailer. The only major difference between the two being that the ones that were on the trailer did no have a ground pig tail and instead the ground terminal was hooked directly to one of the screws attaching the light to the trailer. Other than that they worked just fine.


Comments
After a year I dont have much to update on my review. The trailer light is still going strong!
