Optronics STL42 Series 4 Inch Round LED Light with Mounting Flange Diagram

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.

After ordering July 11th and a roundtrip from Missouri to L.A. to Keswick Ontario, Canada we received the shipment July 25th. Tailights fit my 2006 Ranger trailer perfectly. Thanks to Paul for tracking my shipment when it didn't arrive on the originally scheduled delivery date and keeping me updated.

Product is perfect and quick shipping.



by:

The trailer tail light fit perfectly on our 2011 Montana camper.
I would purchase the lights again!!



by:

Used these to replace old lights on my horse trailer. Installation was easy and they are very bright. I had issues with a connector on my first order, but the second was just fine. I also had issues with one being dim, but found out it was my trailer plug. Once it was replaced, it was great! Would use these on another trailer if needed.



by:

I put these LED lights on my 1967 Scotty. They have a nice clean look, and show up so much better than the originals. The wiring process, with the plug in connections, was easy!



by:

I always find the right parts for my boat trailer. The service is great I like to keep a spare set of lights for my2008 Ranger trail trailer



by:

All the trailer lights were OEM and fit perfectly



by:

Great lights, very bright and visible day and night, much much better than the factory bulb light. I have recommended them to our friends who have RV's
Thanks etrailer



by:

Thanks... the light is perfect and at a great price. The other place wanted $26.00 for the same light and you charged much less. I highly recommend etrailer.com for parts.



by:

Perfect fit, wiring as described! Perfect upgrade for our 60s Sears Tent Trailer



by:

100 times better than the original lights I had with traditional bulbs. With the LEDs you can see them even better during the day. Which is nice to know that people can see me at all hours of the day.

Shipping could be faster

Still working great. Would recommend to anyone!!

Light fit perfectly on my trailer and got here Amazon fast.



by:

Lights are great and fit perfect in my ‘09 Z520 Ranger boat trailer. Only reason for the 4star rating is because some of LEDs went out in the first set I bought. Four of the ten diodes would be lit but very dim. Thought it might be a ground wire or something on my trailer. It was not. This happened about three years after I put them in. I guess for how easy/inexpensive they are, it’s a good value still.



by:

These lights worked out great. good price too!
EZ install.

I used these lights in conjunction with a wig-wag flasher unit to build a Railroad Crossing replica for my model railroad train room. Works and looks great in the sun-blocker shades I built around each.

Great service, great product

These LED tail lights are exactly what I have been looking for to renovate a trailer with recessed lights. I was excited to find them available from the etrailer company. Placing the order was easy, the company notified me when the order shipped, and the lights were delivered in a VERY TIMELY fashion!! This company has earned a 5 star rating, as well!

  • Can Sealed, 4" Round LED # STL42RB be Ran as Extra Stop/Turn Signal Light
    The Sealed, 4" Round LED Trailer Stop, Turn and Tail Light, Flange Mount, 3-Function, 10 SuperDiode # STL42RB can be ran to the rear of a vehicle as additional stop/turn lights. Basically you'd just need the correct install harness like the # A47PB which you'd wire to the vehicle wiring and you'd be set.

  • Replacement Taillights, Wiring and 7-Way Connector for Car Hauler
    To fit the round 4-1/2 inch holes on your trailer for the rear brake lights you could use the # STL42RB as this will fit in that hole. For a pigtail harness you would also need # A45PB. For the side clearance lights you would need to enlarge the holes to 3 inch in diameter, use the # A55GB as a grommet and then use # MCL59AB for the lights and # A46PB as a wiring harness. For a replacement 7-way with 8 feet of wire for running new wire everywhere you would want the part # H20046. You...

  • Is there a Trailer Tail Light that Matches Peterson Back Up Light # 411SC
    We do not have an exact match for a red round tail light like the Peterson Back Up Light, # 411SC, that you have referenced that is a flange mount. The closest flange mounted lights are going to be the Peterson round tail lights # 431800 and # 432000. For a flush mounted light, you could use # 429800 which may be more what you are looking for. We also have the Optronics brand flange mounts # STL42RB or # ST47RB. They use wiring harness # A45PB.

  • Replacement LED Trailer Light to Reduce Power Draw
    The Optronics LED Trailer Light # STL42RB is not what I could call an exact replacement for the # ST40RB but for all purposes it will be what you're looking for. The # STL42RB is 1/8 inches larger in diameter and 3/8 inches deeper so at the most you may need to do a little filing to the opening for the light in your trailer to install it. The mounting flange is metal. There is also a Stainless Steel Trim Ring # A5TRSSB available. It does not include a gasket, however If you would prefer...

    We have LED trailer lights available. If you have the dimensions of the light you want to replace that would help in finding the right replacement for your Pacific trailer.

If you need a flush-mount light, we also have part # STL43RB. this is also a 3-function 10-LED light. If you are looking for an oval...

  • Converter Recommendation to Install Combined Taillights on a Flatbed Truck that had Separate Bulbs
    It sounds like you need to convert the separate wiring of your 1991 Nissan truck to a combined setup to work with the Round LED Taillight # STL42RB. For this you will need to get a Roadmaster Brite-Lite Wiring Converter # RM-732. You will run the wires from your vehicle to the right side of the # RM-732 by function, and then from the left side of the box you will run the corresponding left or right turn signal wire to the red wire of the # STL42RB. The tail light circuit will bypass this...

  • Availability of LED Amber and Red Clearance, Tail Lights, and Side Marker Trailer Lights
    The STL42RB does come in amber. It is # STL42AB. Use wiring harness # A45PB with it. For 2 inch diameter amber lights you can use # MCL50AB with # A49PB and # A54GB. For 2 inch diameter red lights you can use # MCL50RB with # A49PB and # A54GB. For amber teardrop lights, you may be able to use # CBL22AB. We also have a teardrop shape kit that you would use on the roof of a truck, # CB-15AK, but it is not LED. For red teardrop lights we also do not have an LED option but we do have the...

  • Troubleshooting Running Lights Circuit on a Travel Trailer Tail Light Harness
    Since you have tested the 4-Way connector on your vehicle and it is working properly, it leads me to believe that the wiring of the lights is incorrect. You will want to make sure that the fuse for the running lights on the vehicle is not blown. It sounds to me like the lights you have only have two wires coming out of the back for wiring to the trailer connectors wiring. If this is the case then the red wire will connect to the yellow (left) and green (right) wires on the trailer lights....

  • Replacement Option For Glo-Brite 9891-88 LED Trailer Tail Light
    We do have an option for you to replace your Glo-Brite 9891-88 LED trailer tail light. Based on my research this is a 4 inch round LED tail light that uses a 3-wire plug and fits in a 5-1/2 inch grommet. We have exactly that with the following light: - Optronics LED Trailer Tail Light # STL42RB This comes with the grommet, which has mounting holes separated on center by 4-1/4 inches, so the only other thing you will need is the 3-wire pigtail, and you can choose from a standard or right...

  • Correct Wiring Needed to Install Optronics Round LED Trailer Light
    To install the Optronics Round LED Light # STL42RB you can use the Optronics 3-Wire Pigtail # A45PB. This has the three 20 gauge wires for stop, turn, and tail light functions. The red wire is for stop and turn, the black for tail lights, and the white is the ground wire.

  • Replacement Round LED Stop/Tail/Turn Light for 4-1/2-inch Opening

  • How to Connect the # STL42RB Tail Lights to a 1958 Trailer with 2 Wire Lighting System
    The 4 inch Round Sealed LED Stop, Turn or Tail Light, item # STL42RB, uses a 3 wire pig tail, item # A47PB or # A45PB, to connect to your existing trailer wiring. The plug on the pigtail plugs into the back of the tail light and is then hard wired to your trailer wiring. It sounds as if your original tail lights were grounded to the trailer frame through their mounting studs, so a third wire was not needed. When connecting the 3 wires from the 3 wire pig tail, you will ground the white...

  • Replacement Tail Light for 2009 Ranger Boat Trailer
    Sometimes it is possible to replace a broken trailer light with one that uses a different type of installation but since we offer a very wide range of lights you may very well be able to find an exact OEM-style replacement. It sounds like you have a light like # STL42RB which has a 3-hole mounting flange. I linked our main page for trailer tail lights of all shapes and sizes.

  • What is Needed to Replace Incandescent Lights on Trailer to LED Assemblies
    You can absolutely replace the incandescent lights on your livestock trailer with LED assemblies. Other than replacing the lights themselves, there is nothing else that you will need to do. Your existing wiring (assuming it is in good condition) can be left untouched. You will find that the new LED replacements will provide a brighter light on your trailer and also won't require near the power demand that your current incandescents need.

  • Replacement Optronics 5-1/2 Inch Diameter Round LED Trailer Light
    I think the part number you have on your trailer is part # STL42RB. The other numbers may be a serial number or another number for a mold or something else. The best way to see if our light is the exact replacement is to check the specs and the mounting of the # STL42RB. The light has 10 LEDs and uses a 3-prong plug like part # A47PB for the right angle plug or part # A45PB for the straight plug. The dimensions of this light are 5-1/2 inch diameter and 1-15/16 inches deep. The mounting...

  • Replacement for Round Tail Lights From Superbrightleds
    Hello Britton; the closest thing we have is the Optronics LED Trailer Tail Light # STL42RB. This has the same 5-1/2" overall diameter and requires a 4-1/2" round hole for installation. It also uses the same 3-prong plug you have now. It has less diodes but it is still a bright light. The number of diodes doesn't necessarily mean a light is dimmer or brighter. The one thing I didn't see listed is the distance between the mounting holes. The Optronics light measure 4-1/4" center hole to...

    The diameter you are looking for is 4-1/2" on the # STL42RB. This would be the widest part that would fit into the hole on your trailer. We do not have an LED option without the plug but we do have the Peterson # PM425-3. This has the same mounting hole dimensions and is also 4-1/2" at the widest point on the back. If you decide to stick with the Optronics light you will need the # A47PB or # A45PB.

    The closest backup light that we carry to the 4 Inch Round LED Trailer Light, # STL42RB, is the 4 Inch Round LED Backup Light, # BUL11CBX. This is a 4 inch round clear back up light that has an overall diameter of 5-3/4 inches and a depth of 1-5/8 inches.

  • What is the Power Draw of Optronics LED 4 Inch Round Trailer Tail Light # STL42RB
    Because tail light # STL42RB has more than one function it has more than one amperage draw rating. Brake lights and turn signals draw more power so that will be the higher draw at 0.413 amps. Running lights use less power and would be the 0.26 amps. If you have the running lights on and then step on the brake, the brake light overrides the tail light. If you have the brakes on (with or without the running lights on) the turn signal will override the brake light on that side. So the most...

  • Newly Installed LED Trailer Lights Go Out When Brake Pedal is Pressed
    This sounds like a ground issue. Ground problems normally show up when there is more draw on a system such as when you have the running lights on and then use another function like a turn signal or brake light. Make sure that the vehicle side and trailer side connectors are clean and free of corrosion inside and out. The main connector grounds should be attached to clean and corrosion free bare metal surfaces. The light grounds should also be attached to clean and corrosion free bare...

  • Can Utility Lights in Trailer Run Off Running Light Circuit Through a Switch on an Aluminum Trailer
    Yes, you can run the switch power wire to a clearance light but the trailer would have to be connected to the vehicle with the running lights on for the interior lights to have power. Aluminum does not offer the best ground so if the lights do not work you may have to run a jumper ground wire to a steel component or the main trailer connector ground. I would try it first to see if there is any problem with grounding to the aluminum surface. A fuse is not needed though you could add one...
