This is a sealed, round LED combination stop, turn, and tail light. The LEDs in this light are super diodes for exceptional brightness and performance. This red light measures 5-1/2" in diameter by 1-15/16" deep, including the flange. Lens and housing are one unit that is sonically sealed and waterproof, providing protection to the 10 super light-emitting diodes. The light draws 0.413/.026 amps at 12.8 volts. This light flange mounts through the three mounting holes spaced equally on the flange at 4-1/4" apart. A separate, industry standard, three-prong plug is used for the wiring connection to easily upgrade from incandescent lights. A three-wire pigtail (sold separately) is required to complete the installation.

Today were reviewing part number STL42RB from Optronics. This is a sealed round stop, turn and taillight for your trailer. Were going to turn off our overhead lights and Ill show you how this works. Thats your taillight and I dont know if you can see, but all ten of the super LEDs are lighted. Now for your brake pedal, theres your brake light, and I dont know if you can see it but the six LEDs on the outside of the unit shine more brightly than the four LEDs in the center to make it super bright, and that should capture, definitely should capture the attention of the drivers behind you and hopefully keep you a little safer on the road. Heres your turn signal and for that also the six LEDs on the outside will shine more brightly.
Now we can turn our overheads back on and I can show you some other features of this light. First of all it does use a standard three-prong plug. Today were using this pigtail, part number A45PB, and this part is sold separately. Im going to put that aside for now so I can show you some features of this light. First of all as you can see it is flange mounted and it is sealed so there should be no water coming in there.
So thats a good thing. Also, because its flange mounted it will be harder for someone to steal this light off of your trailer, and because its flange mounted also its easier to retrofit your incandescent lights that youre using now. So its real easy to switch to LEDs, and as you probably know, LEDs burn thousands of hours as opposed to a couple of hundred hours for incandescent bulbs, and they also burn more coolly than incandescent bulbs. Theyre not so hot so thats an advantage also. Let me show you some of the measurements on this unit.
The light itself is 4 inches in diameter. With the flange mount its 5 inches in diameter, and its 4 inches between mounting holes from center to center. It has three mounting holes. Now lets turn this over and look at some of the measurements on the back. From the surface mount here to the flat top of the unit is 1 inch.
Now if you measure from the surface mount to the top of the socket for the pigtail thats 2 inches so the total depth is 2 inches. Now if youd like, you can use this steel mounting bracket thats sold separately. Your application may even require that you use it. This is part number BK45BB and the flange mounted light fits in very snuggly so nothing should be leaking in there. And, that is it for part number STL42RB, the round stop, turn, and taillight with ten super diodes made by Optronics.

After my wife has been nagging me for the last few years to fix her custom 5th wheel horse trailer I finally decided to take the plunge. Replaced the old light with these great new LED lights. Super bright and look great. LED lights are very sensitive to ground. This trailer has living quarters as well and the manufacturer made it of tube aluminum then used a torch to cut holes to run the wires in the tubes. The jagged edges over time have caused numerous shorts which all had to be tracked down and wire repaired as needed. When you have a large system that may have a short you can tell when you plug the trailer into the vehicle and the engine drops rpms. This trailer has fuses that once they reach a certain temp they turn off and then will come back on after they cool off. I'm very familiar with my trailer today 136716
Top quality product. Easy to install. Replaced ancient (41 yr old) incandescent bulb units. 224247
by: Nick young06/05/2016
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. 257650
by: Sheryl S08/16/2016
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! 284520
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 324829

Have used this light before on my boat trailer and although it installs easily, the last one didn't seem to last very long. I am not sure how long they should last, but it couldn't have been more than a few years. The company service and website is excellent and a great source for the necessary parts one needs. I also enjoy their tutorials. 92198
by: Tony A08/06/2015
Excellent product that was virtually impossible to find elsewhere. The price for two was less than the price for a single light of the same type from an Ebay seller. Perfect fit for my boat trailer. Replaced non-working incandescent light as well as the one that was still working. Will definitely buy from you when I can. 217193
by: Tom R.01/29/2016
Updated my stock trailer to led lights. They provide much more visibility. Had to grind out my trailer opening a little bit for an exact fit; however, this was easy to do. Product works great and much more economical than purchasing at local dealers. Would order this product or similar item again. 236508
Used to replace incandescent sealed lights on gas delivery truck. LED lights are 100% better and brighter, you can't go wrong. Being seen is no longer a problem, even in inclement weather. Great product from a Great supplier. Order it on your time and it is their before you know 345869

Replaced old post mount trailer lights with these flange mount LED submersibles. No more popped bulbs and bloody fingers from replacing them in rusty sockets every time I put the boat in the water. Great service, nice folks at etrailer.com. Thank you 23168
by: John C03/19/2015
This is a direct replacement in terms of form and screw pattern for the lights used on my Montana 3800 fifth wheel trailer, but a major improvement in safety over the unsealed incandescent bulb lamp assembly used by Keystone. What's not to like. 179815
by: Jesse S.10/09/2014
Fast delivery. Original motorhome led lights would not light up as needed and were sporadic. The original type were no longer being made. Adapted your lights and harnesses to solve my problem. So far your the lights and harneses work as expected. 155434
by: Chris R10/25/2013
This product should come with the pigtail for 17.00 dollars you can buy the light with the pigtail at the local farm supply. If nothing else it should be much more clear when you select this item it does not come with the pigtail 105215

Lights work as designed. Had no problems with installing on utility trailer or testing. Have not had a chance to use at night yet. I am guessing they will be much brighter than the old lights. 47392

Replaced my old tail lights on my pop up with these super bright LED taillights. If you have trouble with the lights flickering, make sure the ground wire is fastened tight. Fit was perfect! 98960
by: Randolph E.02/26/2014
Bought a 3 wire to 2 wire converter and changed the tail lights to the new LED. The turn signals still wouldn't work so I replace the flasher and all is perfect. I am HAPPY, HAPPY, HAPPY! 117808

Just what I have been looking for to replace the factory installed lights. I had two burn out and was looking to upgrade to the LED but could not find them locally. 163387
by: Tom T02/21/2011
We are installing them now and they look like they will do the job perfectly. Hope they last a long time because the individual bulb type seem to break all the time. 7560
They worked as they were supposed to. I did have to file the mounting holes just a tad from the old incandescent fixtures, but other than that.. all was good. 254849
by: Christie Twisdale09/03/2014

The finished product is great. The lights are much brighter than the original ST42RB. After adding the pigtail, the light fit the existing opening. 196664
