Video Transcript for Optronics Trailer Lights - Clearance Lights - MCL35A32G Review

Today we are going to review part number MCL35A32G. This is the Optronics rectangular LED marker clearance light, amber in color. This reflector lens will eliminate the need for a separate reflector for DOT compliance. This has a stud mount black base and a replaceable lens. It does include a 32-inch lead, has a molded connector on the end. And this is a stud mount so it is grounded by mounting to the vehicle or trailer.

I'll give you a few measurements on this light. The width is 3-7/8 inches. The height is 2-3/8 inches. The depth is 15-1/16 inches. The dimension between the mounting holes, center to center is 3-5/16 and I do have a power supply here.

I'm going to hook it to you an idea of the brightness of the light. Hook up the power and then as you can see we are going to be grounding it to one of the mounting holes and with the lights on, that is how bright and we turn the lights off. It gives you a good idea how bright the light is. And that should do it for part number MCL35A32G.

3-7/8" x 2-3/4". Low-profile LED trailer light functions as a clearance or side marker trailer light. Built-in reflex reflector. Durable polycarbonate housing. Surface mount - hardware not included. Single wire design. P2 rated.


Replaced both my side markers a little more than 6 months ago and they work without fail.


I ordered these lights for a boat trailer. They are submersible and their dimensions for mounting were perfect, no rework needed to install them. The price was right and I hope they last longer than one season. The lights I had on lasted one season. They haven't been in the water yet but they appear to be sealed well so I think they will work for this season and hopefully longer.


etrailer had the exact part I was loyfor at a very reasonable price. The item arrived when expected and we’ll packed to prevent damage.


Fast and quick service! Nice quality p roduct!!


Lights were just what I was looking for!


Perfect match to replace an original marker light on my 1980 HMV Freeway. The only difference was I upgraded to the LED. Light was delivered in a very timely manner and packaged securely.


Quick shipping. Great product. Easy installation. Still as bright as it was new when I purchased it a year ago. Great company!

Still working fine

These marker lights are well made and is a great company to do business with.


These LED clearance lights replaced the unreliable incandescent lights that came on the trailer. They're a lot brighter than the old ones. I didn't use the plugs but spliced them into the wiring harness.u

Still working good after a year.

Excellent quality. Looks great illuminated. Crisp lighting. Figures now there’s free shipping.


Replaced the boat trailer lights and bunk boards, fenders and added a set of guide post and rachet straps, now my boat trailer lights up like achristmas tree and has never been easer to launch and load, thanks etrailer, great products fast shipping and great customer service, accidently ordered the wrong size fenders and the folks at etrailer got me the right ones, fast, easy and couldn't have had a better experience, thanks again


Product was what I had ordered. Was proud to take delivery of such a fine looking trailer. Added a UV stain seal to the deck as it was only a soft wood - kind of disappointed with the deck and only one screw at each location. Trailer lights were great in the back, but minimal on the sides, so I ordered a dozen LEDs for the sides. Added reflectors to sides and back, too. The trailer had 24 stake pockets that fit nothing. Will need to custom cut 24 boards for the stake racks.


In replacing my existing lights, i switched to these LED versions. They are much brighter than the 1157 lamps i had. I had the incandescent version and they mounted to the same brackets without drilling. very quick and bright conversion.


Light works - had to redrill a hole on each side of trailer. Holes did not match up with original light manufactured by West Bar (off by a hair). Can't find female connector at any store. I'll have to put in a separate order.


Still working after 1 year in and out of salt water. Overall build quality is ok. The supplied wire end is useless.


I was very surprised and disappointed to see,
that the internal parts that ground the light to the trailer frame are NOT made
out of stainless steel !!!
The light is advertised as SUBMERSIBLE, but in all honesty:
How long do you think that these lights will last on a boat trailer in Florida???
Before installation, I coated the the metal grounding connector with
heavy duty rust preventive spray, but I doubt that this will help in the long run!


Replaced old incandescent trailer lights. After one year, still working fine. Nice and bright.

Retain their brightness and working great.

I shopped around for trailer lights in my area, unsatisfied with results I decided to look online. I found e-trailer and was astounded by product selection and price!
I will be looking for trailer accessories on e-trailer from this point forward.
I am still working on my 16ft trailer and hope to send some pics with accessories installed.


Great product. E-trailer did their part on shipping the product out quickly, but UPS and the post office took almost 2 weeks to get product to me. Highly recommend using UPS only...I have no problems with E-trailer at all. Have bought from them in the past and I will certainly buy from again!


Arrived quickly and packed adequately for delivery. Exactly what I ordered...and fit onto my three wheeler perfect. Replaced an original "Peterson" marker light exactly with exception of the LED bulb. Does not include mounting screws.


I installed these on my trailer as soon as I got them. I used self tapping screws and it was very easy. Love the look.


Great direct replacement for the incandescent version that I used to have on my trailer.


I was worried these would not work out but they were perfect. My trailer is ready for the road and we are going fishing tomorrow. Thanks for getting the order out to me so quickly!


Nice bright light! Much better that the standard lamps on my boat trailer. I like the plug already installed too. Screw on and plug in . .


Easy to install still works as advertised after one year of dunking trailer into salt water
