Video Transcript for ONE LED Trailer Tail Light Spec Review

Today we're going to be taking a look at part number STL003RFLB. This is the Optronics round LED trailer light. It's going to feature one LED. It's going to serve as your brake light, turn signal and taillight. It's going to feature a sealed waterproof housing, as well as a lens unit. Here on the back side, you're going to notice that it has the connection point for a three wire pigtail.

These tabs that come off of here are actually locking tabs, so once that connection is in there, that bracket or that housing on the back of the plug is going to lock in these brackets and that's just a safety feature, as well as a feature that's designed to prevent theft. It's going to clip on either side of the plug for a nice, tight, secure fit. This uses surface mount technology, which is designed to protect the LED from shock and vibration. The diode is actually mounted directly onto a circuit board instead of through a hole. It's going to feature a long lasting LED. It's going to be a great replacement for an incandescent light.

LED's are going to last 50 times longer, you don't have to worry about replacing bulbs. You don't have to worry about brittle filaments and LED's are going to be more efficient, so they're going to provide brighter light with less power output. It's going to feature a sturdy poly-carbonate lens, as well as a housing. This is Department of Transportation compliant, so it meets FMVSS 108 requirements and CMVSS requirements for automotive lighting. We'll take a look at the overall dimensions real quick. It's going to give us an overall diameter of 5 1/2 inches.

Now the actual light itself, or that lens, looks like it's going to be about 4 1/4 of an inch. The depth of this unit is going to be about 2 inches. You can see here that this is going to be a flange mount design, so it has that flange that goes around the housing. That's going to have three mount holes. If we take a measurement, the distance that we have center on center between each hole. That's going to measure 4 1/4 of an inch, and that measurement is going to be the same no matter how you measure, center on center between all the different holes.

So you have three different holes, center on center 4 1/4 is going to be the separation. Optronics is going to put a lifetime warranty on the LED. Again, you have the three prong connection here at the back. A couple different options that you have, it does not include the plug that you need, so you can find that here at etrailer.com. It is going to be sold separately, part number A45PB is going to be the one I'm using for our demonstration today, or you can get a right angled plug, with part number A47PB. I'm going to go and hook this up to our external power source, that way you can see what it's going to look like with power running to it. Simply just take our plug, run it through the guides there, that is locking tabs, straight into the connections. It's going to snap into place. You can see there that once that is fully connected, creates a nice tight seal around those connection points, so nothing is going to get in there and do any damage. This is going to be the taillight function. Again, this is just one LED. When we apply our brakes, you can see how that brightens up for a brighter signal output. It's also going to do that when we activate our turn signal. That's going to do it for today's review of part number STL003RFLB, this is the Optronics round LED trailer light. .

  • Replacement Round Trailer Tail Light For A 4" Tube Light Cover
    Hey Michael, No, the # STL003RFLB has a 5-1/2" diameter so it wouldn't be able to fit. With a 4" spacing you would need to go with a light like the Optronics Trailer Tail Light # ST20RS, which is 3-7/8" in diameter. This should have no problem sliding to the back and has a mounting holes 2" apart.

  • 4 Inch Diameter Trailer Tail Light Options
    We do have a number of options for trailer tail lights that are 4 inches in diameter, although the standard for these lights is a 3-wire system: ground, turn signal, and tail light. Your lights may have grounded through the mounting hardware, but these lights will use a wire for that. The options I recommend are LED because they are going to last much, much longer and have a lesser power draw than incandescent lights - Peterson LumenX LED Trailer Tail Light - Stop, Tail, Turn # M824R-7...

  • Comparing Optronics # ST40RB and Optronics # STL003RFLB Trailer Lights
    Aside from the Optronics # ST40RB having an incandescent bulb and the Optronics # STL003RFLB being LED the only other big difference is that the first part grounds through the mounting hardware while the LED version grounds through a wire. This is why one unit has 2 wires and the other has 3. We have 2 pigtail options for the LED verison for you to use. Part # A45PB has the wires coming straight out of the plug while part # A47PB has a right angle for tight spacing where your lights mount. I...

  • What To Check When A Trailer Tail Light Stops Working
    If the brake light is working, but not the tail/running light, there will be one or two things going on. First, the LED has gone out and the light will need to be replaced. This does happen after a while and is a pretty common occurrence. Quick and easy way to test this is to use a tester, like the # PTW2993, to make sure you are getting power to the light through the plug. You will need to determine which port is your ground, but the port for the brake should only have power when the...
