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.

These lights are used as the tail lights for my Atlas Balebed. I paid for Priority shipping and came within 2 days. They were an exact match and work perfectly. I liked the close up pic on the website so I could match the numbers on my burnt out light exactly to the one I was ordering so i was sure I was getting the same light. 569802

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

by:

Lights appear to be exact replacements for my trailer's tail lights however the electrical sockets on the back side all required modification in order for the electrical plug-in to fit. The sockets were too small for the three plug-in probes. A drill bit shank worked well for expanding the sockets. 432168

I’ve nothing more to add other than the fact that they still work.

E trailer did a good job on the ease of ordering replacement tail lights for me, quick shipping as well. My only complaint about this product and not E trailers fault, is the fact that the manufacturer says these are long lasting bulbs. I have had my trailer for 8 months with occasional use and 1 burns out.....? I will see with the new ones how long "long lasting" is.....Thanks!! 132470

Follow up to my last review a year ago, These bulbs are great!! I put E trailers lights in and have not had any problems at all!! Getting ready to order more for another trailer I bought...Thank you!!!!

Poor....the light works but when you press the brake, the light does not indicate the brake is depressed. Maybe it is my problem, but bottom line it is not working satisfactorily. 754916


Comments
The first step in determining what the issue with the light is to test the wires at the back of the light using a circuit tester, like # PTW2992
LCD Digital Circuit Tester
$31.25
. There are 3 wires on the back of the light. One is the ground and wont have a signal read. Another wire will be the tail light wire that turns the light on. The last wire will be the stop/turn signal wire. If there is a brake/turn signal indicating on the wire, then there is a problem with the light itself. If there is not a brake/stop signal on the wire behind the light, then the next step is to trace the wire and check for any damage that may be causing a loss of signal.

Ask the Experts about this Optronics Trailer Lights

  • 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.

  • 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.

  • 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.

    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.

    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.

  • LED Trailer Light Recommendations for a Trailer Over 80 Inches in Width
    I attached a help article that details all of the various taillight requirements for trailers based on their dimensions. A good kit to start with would be the part # TLL36RK, for an ID bar part # MCL84RB and then for red ID lights for the rear part of the side of the trailer part # MCL-91AK.

  • 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.

    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. If you want the LED option it is the Trailer Tail Light - Stop, Tail, Turn - LED - Waterproof - 10 Diodes - Red Lens # STL72RB and this light uses that same 3-wire pigtail.

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...

  • 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....

  • 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.

  • 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...

    When replacing your 6-1/2 inch oval tail light like the Optronics Sealed # ST70RB that does not have any visible screws on your boat trailer, you can remove the assembly by simply pulling it out of the existing grommet. You can wiggle it back and forth to get it loose and you may need to use a screwdriver to put a bit of pressure on the edge. Then when replacing the light, you will just snap the new light back into the grommet after connecting the 3-prong plug. I have attached an...

The red wire is for the turn signal/brake, the black is for running lamps and the white wire would ground to the trailer frame. The lamp can be flush mounted using the # A70GB grommet.

  • Load Resistor Recommendation for Use with LED Tail Lights on a Flat Bed Truck with Hyperflash
    You will wire a load resistor into the wiring of each light socket that has an LED bulb and flashes. So basically you will need to wire a load resistor into any bulb that blinks or has a dual intensity feature that lights up when the brakes, blinkers, or emergency flashers are operated. To do this correctly, you will need to wire the load resistor on the positive wire and then either ground it to the ground wire of the bulb, or to a good frame ground. You will need to do this for all...

  • 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...

  • Will Optronics Sealed Oval Trailer Stop Light Replace the Bargman Light on my 2002 Homesteader
    It will fit Bargman part # 40-06-001. Since your light is a Bargman unit, you will just need to find the part number on it somewhere. The DOT 97 number has to do with Department of Transportation regulations and you will see similar numbers stamped on most lights. If you find 40-06-001 on the light, then this Optronics light will work as a direct replacement. If you find a different part number, please write back and I will help you find exactly which light will fit.
