Optronics ST70RB Oval Sealed Tail Light 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.


Recessed-Mount Light

Recessed mount light

Recessed-mount trailer lights install underneath a housing or a grommet (A70GB - sold separately). These lights will extend into the mounting surface and require that a hole be cut into your trailer.

Received the correct light for my truck. Good price and shipping was relatively quick.However, I am not too happy about the fact that I have to throw away a perfectly good light housing since the only problem was a blown bulb! Very wasteful! 729169

  • Replacement Tail Light for Wesbar 108121
    The Wesbar 108121 has been discontinued but the Optronics Trailer Tail Light - Stop, Turn, Tail - Submersible - Incandescent - Oval - Red Lens # ST70RB is the ideal replacement. It works with the PVC Grommet for 6-1/2" Oval Trailer Tail Lights # A70GB. This light will use the standard 3 prong plug that if you need a replacement is # A45PB or # A47PB for the 90 degree connector.

  • Bargman 40-06-001 LED Replacement Trailer Tail Lights
    Yes we do! The LED light that is comparable to the Bargman 40-06-001 and the Optronics # ST70RB that you referenced is the part # STL002RB with the staggered 3 pin connection. We also have the kit # TLL12RK which comes with the same size lights, grommets, and pigtails. The only differences are that they have a slightly different lens design and they use 12 diodes as opposed to 1. Installation videos have been linked for you to reference as well.

  • How to Remove Grommet-Mounted Tail Light for Bulb Replacement
    Usually lights that mount using a rubber grommet will need to be popped-out of the grommet to give you access to the lens for removing that part to allow for bulb replacement. You can push the light out of the grommet by moving it out from the grommet, toward you as you look at it. For instance, the red oval light # ST70RB from Optronics uses grommet # A70GB for installation. This light is a exact replacement for Truck Lite part 60202R and others as listed on the linked page.

  • Availability of 6-1/2 Inch Oval Trailer 3 Function Light w/ LEDs
    We do offer a light with LEDs that is very similar to the Sealed, 6-1/2 Inch Oval Trailer Stop, Turn and Tail Light, # ST70RB. For this you would need Waterproof LED Trailer Tail Light - Stop, Tail, Turn, # STL70RB. This light measures 6-1/2 inch long x 2-1/4 inches wide x 1-1/8 inches deep. I have included a short video for you.

  • Availability of Replacement # STL-74RBK LED Taillights
    The Optronics # STL-74RBK is a kit that includes the # STL72RB lamp, the # A70GB grommet and the # A47PB wiring pigtail. We don't sell the kit, but we do offer the parts separately. So, if your'e needing the replacement lamp only, you'd need the # STL72RB.

  • Replacement 6-1/2-Inch Oval Trailer Tail Lights
    Thank you for the trailer light lens coding. This is not an actual light part number; this usually appears on the light base. Just the same I think what you're looking for is a product like # STL78RB. This is a sealed 6-1/2-inch oval tail light that uses high efficiency LEDs instead of standard bulbs. You can see all oval tail lights by clicking on the linked page. Click on the filters for lens color, bulb type, etc to narrow down the range of lights shown.

  • Mounting Dimensions of the Optronics 6-1/2 Inch Trailer Light # ST70RB
    I took a few measurements for you that I think will help. I have attached a diagram and made a short video for you showing the dimensions and the light. I believe this light will work with your bumper without having to cut out a hole in the back of the bumper. When the light is mounted in the grommet, portion of the light that extends past the wall of the bumper will only be 1-11/32 inches. You should have no problem installing this in your 2 inch x 4 inch bumper.

  • Replacement Tail Light For Bargman 6-1/2 Inch Oval Light

If you can find that part number on your Bargman light, then we can be sure that this light is the correct replacement. Even if your Bargman light has a different part number, # ST70RB will very likely work. The dimensions of the light are 6-1/2 inches long x 2-1/4 inches wide x 2-3/8 inches deep. If your current trailer light is approximately the same size, this light will work...

  • Replacement for Truck-Lite Trailer Tail Light 60210R
    Yes, the Optronics Trailer Tail Light part # ST70RB will be a direct replacement for your Truck-Lite Trailer Tail Light part 60210R. They both have the same dimensions and the plug is the exact same. If your trailer lights are not working then make sure to check the bulbs, fuses, and wires as well. If you can send me a photo of the marker light you are referring to then I would be happy to let you know how it is removed.

  • Recommended Waterproof Oval Trailer Stop, Turn and Tail Light

  • Installing a Light and Grommet On Trailer Troubleshooting
    Without knowing exactly what light assemblies you have on your trailer it's a bit hard for me to say exactly how to reinstall them, but for the most part you will want to install the grommet first on the trailer and then slide the light into place after similar to the video I attached. You will see in the video that our installer used a bit of grease on the inside of the grommet to help the light slide into place easier.

  • Is Optronics Trailer Tail Light # ST70RB the Same As Petersen Trailer Tail Light # M421KR
    Yes. The M421KR is a Petersen part and the Optronics equivalent is the Sealed, 6-1/2 inch Oval Trailer Stop, Turn and Tail Light, 3-Function, # ST70RB, that you have referenced. For a complete set up, you will need Rubber Grommet # A70GB, and Straight 3-Wire Pigtail, # A45PB.

    For your model 421r light, we have the Optronics Sealed 6-1/2" Oval Trailer Stop, Turn and Tail Light, 3-Function # ST70RB. This light requires the 3-Wire Pigtail for Optronics Trailer Lights - 3-Prong PL-3 Plug - 10" Lead # A45PB.

  • What is the Approximate Amperage Draw of the ST70RB Sealed Oval Trailer Light
    The Sealed Oval Trailer Stop, Turn and Tail Light, item # ST70RB, uses an 1157 automotive style bulb with two filaments. The bright filament is rated at 21 watts and the dim filament is rated at 5 to 6 watts. With the filament wattage, we can determine the amp draw of the bulb. Amperage equals watt rating divided by input voltage. Assuming a 12.8 volts input in all cases, with both filaments lit, the amperage draw would be approximately 2.1 amps. With only the dim filament lit, the amp...

  • LED Replacement for WESBAR 203561 Light
    Yes, the Optronics Trailer Light, # STL70RB, will replace the Wesbar 203561 to upgrade to LED lights. You will want to check the factory grommet when you remove the light, if the factory grommet is in good condition you can use it with the LED upgrade. If the factory grommet is worn or shows any signs of damage, now is the time to replace it. You would use the Optronics Rubber Grommet, # A70GB. Same thing on the 3-prong plug connector, check it also to make sure it is in good condition....

    I pulled up a picture of the rear of your 2016 Triton PWC trailer and the taillights look nearly identical to the part # ST70RB that you referenced. I am confident you could get this light to work with the mounting bracket part # BK70BB or the grommet part # A70GB. For a pigtail harness you would want the part # A45PB.

    We would have no way of knowing a specific trailer light on any trailer, including your 1993 Heritage, so the best we can offer is to tell you how to determine you can use the Optronics Trailer Tail Light # ST70RB. Just measure your light, and if you get the same dimensions - 6-1/2" long x 2-1/4" tall x 2-3/8" thick - then you can use this light. It will also require 3-Wire Pigtail # A45PB or # A47PB.

  • Right Brake Light and Turn Signal on Horse Trailer Stopped Working
    It depends on the light but before trying to replace a bulb are you certain that the bulb is out? You can test the wiring using a circuit tester such as # 40376 or a meter if you have one. If there is power getting to the light AND this is a problem that just suddenly appeared then it is likely a bulb. But if there is no power getting to the light then it could be a problem with the wiring on the trailer or tow vehicle. I have linked a help article on troubleshooting for you. If you...

  • Method of Bulb Replacement on Oval Red Grommet-Mount Trailer Taillight
    Usually a grommet-mount incandescent tail light will be pressure-fitted into the grommet and held there simply by friction from the rubber. If there are no visible screws to allow lens removal and no accessible portion of the light's rear surface then its almost a sure thing that you'll just need to carefully pop the light out of its grommet. Ideally you'll have a tool that is strong enough to flex the grommet material but not so hard that it can damage the lens or base. The light in your...
