This 6-1/2" oval LED trailer light delivers strong, clear illumination for both parking and turn signal functions. With 56 diodes behind an amber lens, it puts out bright light while staying energy-efficient. At 12.8 volts, the power draw is just 0.362 amps on turn signal and 0.013 amps for parking. You’ll get excellent visibility without overloading your trailer’s electrical system, all in a durable LED design that outlasts traditional bulbs.
If your trailer sees wet roads or boat ramps, this light is ready for it. The waterproof polycarbonate lens and housing are sealed to keep out moisture, making it ideal for trailers that need dependable lighting in all environments. You won’t have to worry about water getting inside and damaging the electronics—the sealed construction keeps it protected and shining bright.
Wiring doesn’t get more straightforward than this. The light uses a standard PL-3 connector that works with a 3-prong pigtail adapter—right-angle (A47PB) or straight (A45PB)—to tie directly into your trailer’s existing system. That means no custom wiring or special tools, just plug it in and go.
This light mounts flush into a cutout using a grommet (A70GB, sold separately) for a clean, recessed finish. If you prefer not to cut into your trailer body, you can use the optional mounting bracket (BK70BB, sold separately) along with the same grommet. Either way, you get a solid fit that looks sharp and stays secure even over rough roads.
With LEDs backed by a lifetime warranty, this light is built to last. You’ll spend less time replacing bulbs and more time towing confidently, knowing your turn and parking lights are bright, efficient, and protected for the long haul.

Today we're going to review part number STL70AB. This is the Optronics Flush Mount LED Trailer Turn Signal and Parking Light with the amber lens. Now this amber 6 1/2 inch oval trailer light will serve 2 functions on your trailer. It will provide a parking light and a turn signal light. This light does meet the Department of Transportation requirements in any 360-degree position. Now this is a great replacement for incandescent lights, the LED lights.
There's no bulbs to replace, no brittle filaments to break. As you can see this is a sealed, waterproof housing and lens unit. It does have 56 LEDs with the amber lens. Now this will conveniently accept the industry standard 3-prong plugs, we do sell that separately, and to flush mount it also requires a grommet and a bracket and I am going to show you all those parts here. Now we do sell those parts separately on our website and they're usually listed on the product page for this light as related products. What I'm going to start with is they have the straight 3-wire pigtail right here.
This is part number A45PB. Basically what you're going to do is line the plugs up, plug it in, and it's called a straight because if you'll notice the wires come straight out the back of the light. Now they do offer another 3-wire plug and this is if there's any clearance problems behind your light. They do offer this when it's the right angle 3-wire pigtail plug. It's A47PB. What this one does is you'll notice when you plug it in, line your holes up, there you go.
You'll notice it's a right angle because the wires will come out at a right angle to the light. Now the grommet that is used is part number A70GB and basically you just take your light, pop it right into the grommet just like that and then the last part is the mounting bracket, this metal mounting bracket. You can see it mounts to the vehicle or the trailer. This is part number BK70BB and basically you just pop the grommet right into that opening, push it in all the way. It snaps into place.
Again those parts are all related products listed on this product page. Okay, a few dimensions on this light. I'm going to give you the overall length edge to edge. You'll be looking at right at 6 1/2 inches. The height on it, bottom to top, is going to be right at 2 1/4 inches, and the depth at the narrowest part is going to be right at about an inch and an 8th, and that at the very other end where they have this plastic housing that comes up over the plug, you're right at about an inch and 7/8ths, that depth right there. Now the power draw at 12.8 volts for this light on the turn signal is .362 amps. On the parking light it's .54 amps, and the warranty is lifetime on the LEDs. What I'm going to do now is take one of the plugs and we're going to plug it in. I'm going to hook it up to a 12-volt power supply to show you the brightness and the functions of the light. The 3 wires you can see, the white wire with the eyelet is for ground, the red and the black are your power, the red would be your turn signal and your black would be your parking light. I'm going to go ahead and hook this up and we'll go ahead and once I get this all hooked up we'll go ahead and turn off our overhead lights. There we go. I'm going to go ahead and turn on the 12-volt power and you'll be able to see there is your parking light function with all the LEDs on and then your turn signal function, so you're very bright for the turn signals. Okay, I'll go ahead and turn off our power, turn back on our overhead lights. That should do it for the review on part number STL70AB. This is the Optronics Flush Mount LED Trailer Turn Signal and Parking Light with the amber lens. .
Ratings & Reviews
I am in the process of renovating a 1966 Airstream. I wanted to upgrade the tail lights and the clearance lights. I found etrailer.com on a web search. I ordered the round 4" LED, rubber 4" grommet, and Oval LED clearance light. The round stop with grommet adapeted perfectly into the lens on the Airstream. I will feel so much safer now with the added visability. The lights are stellar.
Direct replacement with no issues, excellent packaging and fast delivery.
Easy to order online, Items arrived during the expected delivery date. Have always had good luck with Optronics products. Just waiting for the truck to get back to the shop so I can replace the old incandescnt lights with the new LED lights.
I had to replace one burned tail light on my 2005 cargo trailer. I bought two and replace the other one as well. They work perfectly. The size and the 3 pins connction are the same as the original. A little downside is regarding the packaging. I would expect each light wrapped individualy to avoid the rattling in the box. See pics.
Exact match to the old light
They work great and we're fairly easy to install as a replacement for the old style brake lights with bulbs....
Good job easy to order and I will be b ack
I have a Haulmark utility trailer. One tail light was giving me trouble and I tried fixing it but decided to just replace it with these. They are brighter and fit right in to the old grommet. They were a bit loose so I wrapped some e-tape around them and they are staying in place just fine. I also ordered the pigtails and soldered and heat-shrinked the connections - the factory connecting were "scotch-locks", which I hate. After I did this, I looked closely at the old lights and realized that there was a 3 prong plug which I might have been able to use rather than doing new connections and soldering them, but by doing what I did, I now have tight connections and I can easily replace the light if I ever have to (I got rid of the scotch locks). Yes, I could maybe have soldered the old connections and used the old plug, but it was constructed in such a way that I didn't realize it was there (I thought it was part of the light body). My picture shows the old light and the old plug disconnected from it and the new LED in place on my trailer. It works great - glad I did this. It's much brighter than the old light.
THESE ARE AWESUM. They even look good when off !! Cant wait to BLIND some tailgaters. Drivers who tailgate boat trailers need to be tazed. I ADDED a Sequential Turn module to each side making them even better. A 3rd brake light wire controls others so only E-Trailers Optronics blink. SUPER BRIGHT !! These pull no power at all so I run 30 LED units or hundreds of bulbs all around the trailer.
Bought these LED Stop/Tail lights for my new dump trailer. The factory stop/tails are mounted very low, and any car directly behind me blocks my lights from the 2nd or 3rd car behind me. So I mounted these new ones up as high as I could to let people know I am stopping or turning. I also mounted a side marker light so I could see where the trailer was while backing up at night. The factory marker lights are so low I can’t see them in my mirrors because they are blocked by the step on the drivers side and the spare tire on the passenger side. I am a retired 18 wheeler driver of 47 years.
I bought these lights for a boat trailer. They are very bright and we're easy to install. I would recommend to anyone looking for replacement lights
Perfect. Exactly what I wanted and needed. Fast shipping. Great communication! Thank you.
Best in class service…quick delivery and the right price.
SuperFast Shipping
Great service the exact replacement nee ded.
Great product if you have an odd ball trailer light set up like I do that requires a center mount position plug! Fast east purchase and fast shipping, great company to deal with!
This light was almost an exact match for the stock light that came on the camper. I bought 2 and replaced them both, and they seem to be a little bit brighter than the originals, which I am glad with.
This light was exactly like described. I purchase a lot on line and use amazon prime for free shipping. I could not find this light on amazon and was very impressed that etrailer.com had very reasonable shipping prices. Instead of gouging the cost was in line what normal shipping cost would be. The shipping and tracking were spot on and the lights were delivered as promised. A VERY good company to work with.
We are looking for a supplier of trailer parts .. they had what we needed.
We build aprox 60 trailers a year. I am going to take a good look to see what else we can get from them.
Identical size, shape & function to the original taillight on a 2-yo Master Tow dolly. Replacement taillight from the mfg didn’t fit the original taillight bezel. This one is an exact fit.
My experience with Etrailer was excellent again as always. Always appreciate the explanation and videos to confirm correct product and installation before purchase. Delivery is always awesome as well.
I have not hooked it up to power, but I'm sure it will work. THe only disappointment I had was the light I removed had a rubber pad to help seal the screw holes and wire entry to the back of my trailer to keep moisture out. This light does not have that and it is not available from your company.
Exact replacements for my old tail lights.Fit perfectly. They also solved the issue. Tho old tail lights were allowing the blinker current to back track through the clearance lights. One of tail lights had water in it and when it flashed the clearance lights flashed too.
While I've not yet installed these they look like good replacements for the OEM lights. They are the correct style, size and the screw hole placement seems to be correct. My only reason for giving them an average rating is that they don't come with any gaskets. The original lights have a gasket between the back of the light and the wall of the camper. While the light unit itself is sealed the wires come through a hole in the camper wall and without a gasket the possibility of leaks is there. I will likely buy some gasket material from an auto parts store and make my own. No, I don't think the camper sealant will work as well as a rubber gasket.
Works great. Installed easily.
