Video Transcript for Optronics Trailer Lights - Tail Lights - STL90R24B Review

Today we're going to be reviewing part number STL90R24B. This is the Transit LED Optronics. The red trailer light is going to serve 4 functions such as your stop, tail, side marker and side reflector light. It's going to feature long-lasting LEDs that are going to be great replacements for incandescent lights. It's also going to feature a multi-diode design that's going to optimize your light output. You also won't have to worry about replacing any bulbs or brittle filaments.

The LED system is more efficient so it's going to provide a brighter light with less power. This system is designed for 24-volt systems. It's going to feature a weathertight seal with the mounting gasket, so that is going to be included. It's got the holes pre-cut in the foam that are going to line up with the mounting holes on the housing of the light, as well as a larger hole here in the center, that way you can run your wires through the center of the gasket. It's going to feature a 3-wire design so it's going to contain your lead wires for power and then your white wire is going to be your ground wire. It has a ring terminal on there for easy connectivity. It is Department of Transportation compliant so it meets FMVSS 108 requirements in any 360-degree position.

It's a nice round light. It's going to give us an overall diameter of 7" with an overall depth of about 1-7/16". It's going to contain 31 diodes, which are going to be the 31 LEDs. The power draw for the stop signal is at going to be 0.180 amps at 28 volts and of the tail light function it's going to be at 0.086 amps at 28 volts. The installation is a surface mount. If we take a measurement, the distance between the 2 mount holes going straight across from one another, center on center, is going to be 6-1/4" and you're going to have 4 mounting holes, total. We're going to go and hook it up to our external power source that way you can see what the light looks like with power running to it and then we'll be able to turn our overhead lights off. Make the ground connection and then we're going to go ahead and connect our stop and turn signal, as well as the tail lights.

You can see here that it's going to put out a nice, strong, consistent signal. I'm just going to make sure that the ground connection is a good strong connection. It's going to put out a nice, consistent LED signal. This is going to be the tail light function. Then when we apply our brakes, you can see how the outer ring of lights illuminates.

It's also going to function as a turn signal as well. That's going to do it for today's review of part number STL90R24B. This is the Transit LED Light from Optronics. .

I was looking for a tail light for a trailer that would operate on both 12 and 24 volts. That way the trailer could be towed by a truck with either a 12 or 24 volt electrical system. There are ways to do it but this would be dead simple. The light is very bright. It appears to be well made. 581608

Bought these for a vintage Airstream. I was initially afraid they may not be bright enough on 12 volts, but after installung them if they were any brighter they would be distracting. I'm very pleased with them. 201588

I actually thought they were going to be two lights in the box. I needed to love them. I would like to order another one, but I’d like to make sure it gets here quickly. I don’t think it was clear in the description that there was only one white. It didn’t say to either, so my mistake in assuming 490705

Having not installed these lights I can only comment on the fact that they look well constructed and are almost identical in size to the lights that came off of my 1962 Airstream Ambassador. They do not mount in the same manner but will cover the holes easily making these a good choice for replacing my old broken fixtures. 571730

These are good looking likes, I used them on my Scamp camper to replace 2 round fixtures, they are at least as bright as the factory fixtures if not brighter. My only note would be that they don't come with screws. 227746

Review from a similar Optronics Transit in Trailer Lights


About the only replacement for an Autolamp 575. Mounting holes line up perfectly, but the foam gasket is not great for vintage use. I removed it and used putty tape. I also opened the lamp to find it had a ground connection that had been cut...very lame. I ended up adding my own internal ground wire to make sure I had a good ground rather than the marginal ground through the mounting screws. 309787

I bought 4 of these to replace the old non-working taillights on my 1967 Holiday Rambler camper. They were easy to install and were the exact same size as the old lights. 224905


Comments

Ive had these on my camper for a year now, and they still look and function like the day I got them. Since that time, I have painted the camper and replaced all of the marker lights. those were also purchased from etrailer. Installed new tires and wheels, and tongue jack. The camper looks like its brand new. Im glad I found etrailer. They have saved me a fortune restoring this old thing. I would love to add new pictures of my camper, but I dont see any option to do that.

I installed these lights on my vintage 1964 Holiday Rambler, and was very happy with the final outcome. They wired into the existing electrical system, and were the exact same size as the original faded lights they replaced. Couldn't find replacement lenses for the original lights, so these were the next best thing. And they worked perfectly. 246975

We really like the new tail lights. We initially wanted the original vintage look ones but they were not easy to find and the couple we did find were very expensive. We ordered these instead and love how they look! Great choice and they arrived super quick! 265796

Review from a similar Optronics Transit in Trailer Lights


Just received the replacement lights and they are as advertised. I needed the large size to cover the 6 1/2" original lights mounting holes. I have not installed them yet, but they seem to be reasonably well made, unfortunately there is no clear lens on one for license plate illumination (I did know that prior to ordering them.) I think that they are a good buy and I would buy them again if needed. 667469

The product was used to replace existing tail lights on my vintage travel trailer that have become dull and faded. These "school bus" type tail lights have a 7-inch base the same size as the ones replaced but, the defusers light the full 7-inches and are more easily seen at a greater distance. A great product. 640859

Do you have a question about this Trailer Light?


  • Tail Lights and Clearance Lights that Can be Used on Both a 12 Volt System and 24 Volt System
  • For a tail light that can run off of 12 volt or 24 volt systems you can use Transit tail light # STL90R24B. For clearance lights you can use # MCL55A1224B for an amber light that works with 12 and 24 volt systems or # MCL55R1224B for a red light. For these lights use pigtail # A46PB and grommet # A54GB. Or for surface mount clearance/marker lights that are 12-24 volt compatible you can use # MCL66A24B for amber and # MCL66R24B for red.
    view full answer...

  • Comparing the Transit # STL90R24B and # STL90RB Tail Lights
  • The difference between the Transit Tail Lights # STL90R24B and # STL90RB is that the former is compatible with 12V or 24V systems while the latter is only compatible with 12V systems. Aside from that they both use the stop/turn/tail functions, are LED, have 31 diodes, are submersible, and have the same dimensions.

  • Option for Towing Trailer with 12 Volt Lights with 24 Volt Tow Vehicle
  • I think your only real option would be to replace the trailer lights on your trailer with lights that are compatible with 24 volt systems since there isn't an adapter available that we offer that would work for converting your 24 volt system to work with a 12 volt lighting system. Right now, we have a few select 24 volt tail lights. We have # STL23R24B and # STL90R24B. For turn/marker lights we have # STL90A24B and # STL23A24B. And for reverse lights we have # BUL23C24B and # BUL90C24B.

  • Replacement Taillight Options for 1967 Airstream Caravel Trailer
  • I have a solution for you, but we do not offer any vintage 575 lights. I was able to find that the 575 lights were round taillights that measured 7 inches in diameter. To replace your exisiting lights with those of the same diameter, we offer both incandescent and LED lights. Our most popular 7 inch diameter, round, red trailer taillight is the Optronics # ST90RB. This is an incandescent, sealed taillight. The three taillight options that come with LED lights are the Optronics #...

  • Trailer Lights Available for a 24V System
  • We do have a handful of 24V trailer light options, but the Optronics Sealed, Flush Mount Tall Rectangle LED Trailer Stop, Turn, and Tail Light, Grommet, and Plug # STL34RB is a 12V light, not a 24V trailer light. For taillights, we have the Miro-Flex LED Red # STL23R24B, Miro-Flex LED Amber # STL23A24B, and Transit Tail Light LED Red Lens # STL90R24B. For clearance lights we have the Thin-Line LED Trailer Clearance/Side Marker Light, Red # MCL66R24B and Thin-Line LED Trailer Clearance/Side...

  • 24 Volt Trailer Light Availability
  • The Light Assembly part # TLL28RK that you referenced is only compatible with 12 volt circuits. We have a couple trailer lights that are compatible with 24 volt circuits though. Check out the part # STL23R24B, # STL90R24B, # MCL55R1224B, or # SLL43AB2.

  • Is Optronics Transit Tail Light # STL90R24B for 12V or 24V System
  • The Optronics Transit Tail Light # STL90R24B that you referenced is actually designed to work with either a 12V or 24V system. If you have a 12V setup this light will still work perfectly. This is a really nice LED assembly with a weathertight seal to protect it from the elements. I have attached a short video review that you can check out as well.

  • Availability of 24-Volt Tail Lights for Lowboy Trailer
  • We do have some trailer tail lights designed to work on a 24-volt system. I recommend using light # STL23R24B. There are a few ways to mount this light. You can use a grommet and flush mount it in a 4-1/2 inch cutout using # A45GB. Or you can surface mount it with a bracket, # BK45BB. You will also use a wiring harness, # A47PB. These parts only come in red.

  • Round Tail Light for Use with 24 Volt System
  • Yes, the Transit Tail Light part # STL90R24B will work on a 24 volt system. I called the manufacturer Optronics, to confirm this. If you need any butt connectors for installation I recommend part # DW05743-5. This light measures to be 7" diameter x 1-7/16" deep. It contains 31 diodes and has a lifetime warranty. I have attached a review video of the light for you as well.
