5-1/2" Diam x 1-15/16" D; Sealed, waterproof; flange mount on 4-1/4" centers; 3-prong plug connection; 10 super diode LEDs
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 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.

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

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 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 you23168
