Optronics 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

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 a side marker light.

Seems like a nice piece. Haven't installed yet, need to find female molex connector to go with it.

Much brighter than the clear lens lamps I installed last year, and far easier to see from behind. Price was excellent!

After a year I still find these to be superior even to the OEM that were put on the coach 21 years ago.



by:

these lights are great. I wanted to replace the middle marker light on my 5th wheel and these woked out very well. Only a little bigger footprint than the OEM ones but don't look out of place on the rig. I've ordered items from eTrailer before and always recieved them very quickly. I took off one star because this time although they had the parts in stock, it took over a week for them to actually ship it. However, customer service always has been and remains excellent.

I found the exact replacement side light to match my custom trailer, reasonable price and quick shipping



by:

These side markers (both red and amber LED) are great for my 12' trailer. They have 3 LEDs (you can also get 4), and their size is perfect for a small trailer. The LED's are really bright, not only at night, but also during the day, so they are easily seen. I especially like the fact that they are sealed, so there should be no water intrusion problems in the future. I have included a few pictures, the first showing the round LED brake/turn/running/reverse lights (that I had purchased earlier from etrailer) with the red side marker mounted vertically on the outside. The second shows a side view of the red side marker light, and the 3rd picture shows the side marker mounted to a small piece of 1" X 1" x 1/8" aluminum angle which I painted black to match the mounting frame of the round LED lights. I mounted the LED side marker to one leg of the aluminum angle, then mounted the other leg with 1" standoffs to two holes already present on the black mounting frame of the round LED light. Although all the lights are sealed against water intrusion, I decided to mount them on each side of the trailer at the top of 2 PVC pipes, about 36" long each, where the lights would not be exposed to immersing in water when launching/retrieving a boat.

I installed these lights in a T@B teardrop camping trailer. The grommet would not work on this style trailer so I installed the lights using a silicone adhesive the same as the original Peterson lights. eTrailer delivered them in the same timely manner I have come to expect from them and the LEDs were easy to install. These lights are blindingly bright - simply amazing. I had rear lights with 1157 bulbs which I had upgraded to 2357 bulbs and equipped the tow vehicle with a powered converter but the light output was dim by today's standards. These lights are twice as bright on running lights and about 4 times brighter on the brake/turn signal elements. The thing we all fear when towing is being hit from behind by a driver that does not see our running, brake or turn signal lights in time. I know these lights will vastly improve the safety and visibility of our trailer. Thanks!



by:

Though I have not hooked up yet…the lamps are an exact replacement for my Toyhauler. Gaskets or screws do not come with these lamps, though there should be a gasket with them. I have material and will make my own (see photo’s).
etrailer does well with follow up email/s along with your order/s. I’ve had no issues with any previous orders as well. Shipping took about a week through USPS.

Great little lights, and very bright as well. They have been installed on a trailer and submerged many times since installed, and still work great!! Can't beat LED's for brightness and, hopefully, longevity!!! Attached is one picture of the overall trailer, and a closeup of the amber side light. I also have 2 red sidelights that are mounted above water at the rear of the trailer, and they are still working great as well.

  • Trailer Clearance Light Similar to STL175AMFB that is Surface Mount
    There isn't a way to surface mount the Optronics clearance light part # STL175AMFB so best option would be to go with a similar light that can be surface mounted like the Miro Flex part # OPT78FR.

  • Comparing Miro-Flex LED Trailer Side Marker Light and Mid-Ship Turn Signal OPT78FR and MCL48AB
    There are a few differences between the # MCL48AB and # OPT78FR. One of them being the delphi plug that comes with the # OPT78FR. this connector provides a weatherproof connection. The # MCL48AB just has the standard 3-wire pigtail. The other difference is the rating. The # MCL48AB is P2 rated while the # OPT78FR is PC rated. Since a PC light meets all specifications of a P2 light the best choice is going to be the # OPT78FR. The PC rating means it will be visible horizontally left-right...

  • Amber Trailer Side Marker Clearance Light With a Turn Signal Function
    The Miro-Flex LED Trailer Side Marker Light and Mid-Ship Turn Signal # OPT78FR is going to be our smallest side marker light that also functions as a turn signal. This light is larger (6"x2-1/4") than the Optronics LED Clearance or Side Marker Light # MCL95AB (2-1/8"x1-1/8") that you were looking at. The light does come with a Delphi connector for a weatherproof installation and you can find the matching end at most auto parts stores. Otherwise you can cut the connector off and wire into...

  • Recommended Red Clearance Light Similar To Miro-Flex LED Trailer Clearance Light OPT78FR
    I have another option for you, but the Miro-Flex LED Trailer Clearance Light # OPT78FR you were looking at is not available with a red lens. The closest option with a red lens is the LED Clearance or Side Marker Light w/ Reflector # MCL76RB which measures 5-13/16" long x 2" wide and mounting holes that are 4-13/16" apart on center as you can see in the included diagram. I included a video review of the # MCL76RB for you to take a look at.

  • How Is The Optronics Miro-Flex LED Side Marker Light OPT78FR Supposed To Be Wired?
    When installing the Optronics Miro-Flex LED Trailer Side Marker Light and Mid-Ship Turn Signal # OPT78FR, the white wire will be your ground source, the black wire will be for the running light, and the red wire will be for your turn/stop signal.

  • Does Miro-Flex LED Trailer Side Marker Light Need Connector
    You would not actually need a connector because the Miro-Flex LED Trailer Side Marker Light and Mid-Ship Turn Signal - Submersible - Amber Lens # OPT78FR comes with its own connector, a Delphi plug, already attached. If your trailer doesn't have a Delphi connector for this light to plug into, there is actually the same exact light available, but with the standard 3-wire pigtail that you would just splice in: - Miro-Flex LED Trailer Side Marker Light and Mid-Ship Turn Signal - Submersible...

  • Trailer Wiring and Lights For Rewiring 5' X 8' Trailer With Reverse Lights And Side Marker Lights
    Both the Peterson Piranha LED Clearance and Side Marker Trailer Light w/ Turn Signal # M353A and Miro-Flex LED Trailer Side Marker Light and Mid-Ship Turn Signal # OPT78FR are sold individually. We do not offer them as a pair for lower price. Since you mentioned replacing your wiring the 25 Ft 5-Way Trailer Wiring Harness # A25W5B is a great starting point. You will need to add additional 20 gauge wire to run the reverse line circuit back to the tail lights. You will need the Tow Ready...
