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

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

I had purchased 2 lights the 1st time I used E-Trailer. Not sure if the truck has wiring issues to be the reason why I had to get more replacements. I purchased 4 more. Some local stores advertised a reasonable fee for these same lights. When I went to the stores the price was 2 to 3 times more. E-Trailer did not do that. I also received them quick. I will not hesitate to order from E-Trailer again. Thanks 703257

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.

  • Replacement Tail Light For Model 421r Sealed Bulbs
    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.

  • 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.

  • 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.

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....

  • 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.

  • 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 Light for Optronics Sealed, 6-1/2 Inch Oval Trailer Stop, Turn, and Tail Light
    For an exact replacement for the # ST70RB, you will want the Optronics Trailer Tail Light # STL70RB. This light has the same 6-1/2 inches long x 2-1/4 inches wide measurement as the # ST70RB. The Optronics Miro-Flex Trailer Tail Light # STL22RB is very similar to the # ST70RB, and could be used as a replacement light to change from incandescent to LED. The # STL22RB measures 6-1/2 inches long x 2-5/16 inches wide. All of these lights use the # A45PB 3-wire pigtail to connect to the...

  • 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.

  • 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 Trailer Light that has SAE ST1PP2 On Lens
    SAE ST1PP2 is the lens rating and not a model number for the light. If your original light 6-1/2" L x 2-1/4" W x 2-3/8" D then Optronics light # ST70RB will fit in its place. If you have different dimensions let me know what they are and I can see if we have anything that is a match.

If you need a replacement grommet for the light you can use the Rubber Grommet for 6-1/2 inch Oval Trailer Tail Lights, item # A70GB, and if you need to wire the light or replace the connector you can use the right angle pigtail, item # A47PB, or the straight...

    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...

  • 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...

  • Can the Bulb in Sealed, 6-1/2 Inch Oval Trailer Stop, Turn and Tail Light, # ST70RB be Replaced
    Because Sealed, 6-1/2 Inch Oval Trailer Stop, Turn and Tail Light, # ST70RB, is a sealed tail light, the bulb cannot be replaced. You would need to replace the whole tail light if the bulb needs to be replaced.

  • Troubleshooting Right Trailer Brake Light Not Functioning but All Other Lights Work
    This sounds like a ground problem. A loose, broken, or corroded ground connection can cause all sorts of unwanted performance for electric components including trailer taillights. I would start with checking for a proper ground at the taillight itself. Many times, trailer taillights ground through the mounting studs. Check for any corrosion and give them a good cleaning to get the best connection. You will also want to check the ground at the front of the trailer for any dirt or corrosion....

  • What is the LED Version of Trailer Tail Light # ST70RB
    The LED version of the light you referenced, # ST70RB, is actually the Sealed, 6-1/2" Oval LED Trailer Stop, Turn and Tail Light, # STL70RB. It has the same measurements and shape but uses LED lights instead. I have included a link to a video review of this light for you. The correct grommet for this light is # a70gb and if you need a mounting bracket use # BK70BB. For a pig tail wiring harness you will need # A45PB.

  • Trailer Brake Lights Do Not Work when Running Lights are On
    First, the 4-Way on your trailer is what is called a wishbone harness. It just has 2 wires for the running light circuit to go to each side of the trailer so that you do not have to run a jumper from one side of the trailer to the other. The issue here sounds like a ground problem. Ground problems normally show up when there is more draw on a system such as when you have the running lights on and then use another function like a turn signal or brake light. Make sure that the vehicle...

  • Correcting Hyperflashing After Installation LED Taillights on 2004 Dodge Ram 3500
    In order to stop your turn signals and brake lights from hyperflashing with your LED taillights, you will want to install LED Light Bulb Load-Resistors, Aluminum # P230004A-2 on the turn light and brake signal wires. Included in the # P230004A-2 are 2 load resistors, so to take care of each side of your 2004 Dodge Ram 3500 you will want quantity 2 of # P23004A-2.

  • 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...
