When you want better visibility without overloading your electrical system, this 4-5/16" round amber LED light delivers. It uses 21 diodes that draw only 0.208 amps for the turn signal and 0.013 amps for the parking light at 12.8V, giving you a bright, consistent output with minimal power use. The LEDs are more efficient and durable than incandescent bulbs, so you get strong light and long service life without worrying about frequent replacements.
If your trailer or rig faces rain, washdowns, or even the occasional boat launch, this light is ready for it. The polycarbonate lens and housing are sealed together to make the unit waterproof. That keeps moisture out so corrosion won’t ruin the LEDs or wiring inside. You can count on steady performance even in wet or humid environments.
This light mounts neatly into your surface using a grommet (A45GB, sold separately) for a clean and secure fit. The recessed design protects the lens from bumps or scrapes while keeping the look streamlined. If you prefer not to cut a hole, an optional mounting bracket (BK45BB, sold separately) works with the same grommet for easy setup.
Hookup is quick thanks to the standard PL-3 connector that works with common 3-prong pigtails like the A45PB or A47PB (sold separately). Once plugged in, it’s ready to function as both a parking light and turn signal on a 12V DC system. The result is bright, reliable illumination that syncs perfectly with your existing lighting circuits.

Today we're going to take a look at the Optronic Sealed Amber 4-Inch Round LED Trailer Light. It's a two function light, parking and rear turn. It has 21 super diodes. This round trailer light will serve two functions as a parking light and a rear turn signal light. It is sonically sealed waterproof housing and lens. These are LEDs and they'll make great replacements for your incandescent lights.
They last about 50 times longer. They're more efficient, which means they provide brighter light with less power output and there's no bulbs to replace or no grill filaments. The housing is a polycarbonate lens and housing. It is an amber lens. This is designed as a recess mount, meaning it does use a rubber grommet that it sits into.
Now, the rubber grommet we do sell separately on our website and it is listed on this product page as a related product. Now, this does accept your industry standard three-prong plugs. Again, we sell those separately. I wanted to show you. There's two versions to choose from. The first one is part number A45PB and that's the straight plug.
In other words, when you go to plug this in, you can see once you plug it in, the wires come out straight from it. The other one is the A47PB and that's a right-angle plug. When you plug that one in, you can see the wires come out at a right angle. Either one of those plugs will work with this light. This is a DOT or Department of Transportation compliant light. A few specs on this.
I want to give you the width, the overall diameter on this and it's going to be right at 4 5/16. The depth measured from here to here is going to be right at 1 1/2 inches and then the depth of just the lens itself is 3/4 of an inch. It does have 21 diodes. The power draw at 2.8 volts for the turn signal light is 1.3 amps. For the parking light it's .010 amps. They do have a lifetime warranty on the LEDs. What I'm going to do now is show you how the light lights up and how bright it is. We're going to take one of the plugs. We'll plug it in. Then you'll have your wires coming out. We'll go ahead, the white wire will be for the ground and the black wire will be for your parking light and the red will be for your turn signal. We're going to go ahead and turn off the overhead lights and we'll go ahead and turn on the 12 volt power supply. There you can see is the parking light. Then when you do your turn signal. You can see how much brighter the light gets using the turn signal. Turn off our power, disconnect our light, go ahead and turn on our overhead lights. That should do it for the review of the Optronic Sealed Amber 4-Inch Round LED Trailer Light with the two functions, parking and rear turn and 21 super diodes.

Replaced the jet ski trailer light perfectly! Lighting is much brighter than the stock incandescent bulb in all modes and light disbursement is very good, even from the sides.
Works best on my boat trailer!
Solid product, fast shipping.
Perfect replacement for the til lights on my trailer. Thank you etrailer for having what I needed, and the detailed information to know it was the right part to order.
Exact fit and an excellent replacement for the lights on my 2006 Ranger Boat trailer.
Fit perfectly to on my boatmate trailer, no issues
Exact replacement, same size, didn't even have to drill new holes. Had looked at many other sites and couldn't find the right size till I checked Etrailer. Thank you so much
The Optronics LED lights fit perfectly on my 2021 Keystone Outback. Installation was easy. It took longer to remove the old sealant.
Replacing original tailights on 2018 ca mper.
I have a 97 Cargo Mate and I wanted to make the conversion to LED lights. The lights and grommets were a perfect upgraded match. So much brighter and better peace of mind when traveling in inclement weather to be seen from behind. Everything was great quality and shipped fast
The lights were easy to install. They are bright lights, very visible in the sunlight.
We installed these on our older dump trailer, replacing the old lights.
They fit perfect, and look and work great.
Great product. An exact copy of what I had installed on my enclosed trailer. It was an easy install with color matching wires. Great quality, easy install and an excellent price point. Can’t go wrong here folks.
I just installed the new trailer lights on our Sundowner horse trailer. The lights are of good quality and replaced the original lights no fabrication needed. The wiring matched up well with the existing wiring.
Perfect fit. Installation took longer than it should due to very poor previous repair performed at the dealer. Glad I chose, at 73 swf, to do rhe work myself. The first time I have had fully functional tail lights since buying in 2022. Woo hoo.
Perfect fit and exact replacement for my 2008 Ranger Z21 trailer. Great price and fast shipping. Totally satisfied!!!
Light was the same size as previous one on EZ Loader boat trailer. Easy to install and very bright. Original one made it 10 years and had moisture inside causing most of the LEDs to stop working.
That 5 is for the product, and especially 5 for the service. Lori always takes the best care of me and I appreciate the opportunity to work with her.
Holding up well, & very bright
Always great customer service. I am always kept in the loop for item delivery.
I have purchased several parts from Etrailer and their service is always excellent.
Good quality and value. Quick free shi pping
The light itself is good, but no plug or wires for a new installation. As well, it was not a fit for what I ordered it for.
Extremely well built light, very bright even mounted about 8" behind the grill!
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 for an Arrow Board on the rear of a truck.
