Today were reviewing Optronics part number STL9RB. This is an LED Submersible Multifunction Light for the driver side. This is a left hand light. It works as a stop light, turn and tail signal and a license plate illuminator, reflex let and a side marker. Its corrosion resistant. Its fully sealed and therefore waterproof, in fact its submersible.
It mounts on studs and here you can see the two stud mounts here that are two inches on center. In the front face you have 10 light emitting diodes. On the side light you have one LED and on the license plate illuminator here with the clear lens you have three LEDs, so there are a total of 14 LEDs in this light. Well turn off our lights now and Ill show you how it works. Theres your taillight and you can see also how brightly the side light shows and heres your license plate illuminator on the bottom.
Heres the brake light and heres your turn signal. We can turn our lights back on. This comes with three wires. White for ground, brown for your taillights and yellow for brake light and turn signal. This is made for trailers that are less than 80 inches wide.
Thats it for part number STL9RB from Optronics, the LED Submersible Multifunction Driver Side Light. .

Upgraded our trailer lights to these. Really like how bright they are in the daylight. Only wish that the wires were a bit longer.84785

This review is more about my buying experience than the product itself, but install was easy and lights looks great. Time will tell how they hold up. Price for product and shipping was competive. Arrived 2 days earlier than expected. Seller follow up with email from an actual person was nice. This is a model for others to follow for doing business online. This outfit is squared away. I will definitely look here first in the future.77416

Went on the trailer effortlessly, I just wish that I could use the replacement lens if I crack the lens, but it appearsthat the lights and lens are one piece. Thanks for the fast service and good price on the unit and the shipping68152

Great replacement product, Also I especially like the replaceable lenses (not sealed) in case one gets cracked. Crack one of the sealed ones and its over. On these, just replace the lens and your good to go. (The diodes are seperate than the lenses)60009

Awesome idea! I've used them for the last several years but, unfortunately, I broke the lens when I hit something. My old ones didn't have replacement lenses, my new one do. If I break them again, it will be a lot cheaper and easier just to replace the lens instead of the whole tailight.57355

Replaced existing bulb application with LED lights. Simple installation, exact fit and look of original, but with LED performance. I would recommend replacing older light sets with these so you can be better seen on the road. 55899

Ordered both left and right matching pair stl9rb and stl8rb , shipping was great came neatly packaged with plenty packing material and shipping cost was excellent in comparison to other sites . The main reason for ordering was i am using an electronic wiring harness in 2011 Hundai Sonata,the standard tail lights on the trailer were incandandesent bulbs and pulled too much current kicking the breaker in the electronic control module on wiring harness , i was aware L.E.D.s draw much less current so when these plus marker lights were replaced .PROBLEM SOLVED , THANKS E-TRAILER52297

These tail lights work very well. Unfortunately they take quite a beating as the trailer is tipped dragging the license plate and banging the light. 22883

Opening the box I thought the order was wrong, I could see a hole into the light where water could enter, but removing the lens showed the lens and circuitry in one piece with the electronics embedded in a clear resin. Really nice design. No chance of corrosion or water issues.21719

Very well constructed and quite bright. Expecting them to last, since there is no hot bulb going underwater like my old ones.19887

Nice product. A bit pricey but I hope they will be more reliable than the old bulb type. With extra lights--9 or 10 small lights, I'm hoping that if one fails the others will still work.18331

Excellent value for the money, easy to install, and VERY bright. I highly recommend these, especially to replace 12V incandescent bulbs, as these LEDs won't burn out and are completely sealed and self-contained.13481

Trailer Lighting I had a large choice of items to choose from and was able to locate just the right lights that I needed to complete my trailer. The price was lower than other sites that I was looking at. The products were shipped extremely fast. I would as in the past buy from this company in the future and would reccomend this company to anyone.3836
