A PC-rated light produces a 90-degree angle of light to either side of its centerline for a total of 180 degrees of coverage. This beam pattern can be clearly seen when you are standing directly in front of the light, as well as when you are standing on either side of the light. When properly installed, this type of light can function as both a front clearance light and a side marker light or as a rear clearance light and side marker light.

I bought these to replace the marker lights on my travel trailer. etrailer had the best price, and they looked to be good replacements. When I installed them they seemed to be as good or better than the lights than came with the trailer. After a year they seem to still look good and work just fine.

After working on the old lights on my camper numerous times just prior to leaving on a trip and while traveling, I decided it was time to replace all of the lights. I purchased two new tail/brake lights, and four new side markers. The total price including shipping was just over $28 (I should have done this a long time ago). The lights arrived within 3 days of being ordered, and I was able to install them fairly quickly. I am so happy that I now have all six lights working perfectly, and shouldn't have to worry about them for a long time

Great replacement for my old weathered lights. cheaper to buy new lights then just the lenses.. Yes these lights come with two bulbs installed.
by: Bryan10/13/2021
like all other trailer lights, failed prior to one year.
by: Jason08/27/2013
I used just the lens cover. Was in a hurry when ordering but was pleased to find out that it fit as replacement on my camper trailer. Had great service from the staff at etrailer. Fast shipping, great communication and awesome site. Will definitely order from them again!

etrailer.com is an excellent online company! The products I received were exactly what I needed to fix up my old V-nose and get it back on the road. The shipping was lightning fast and excellent follow up communications. I would recommend etrailer.com to anyone, any time!! AAAAA+++++ company.
by: J Roy07/29/2013
The light is an exact replacement part. The delivery time was as expected. The web site was easy to navigate and provide excellent information regarding the wiring on the trailer.

Good quality replacement products

Good quality light, just wish the wire pigtails were about 2" longer.
by: Nuria07/10/2015
Though this is a more modern version of the marker lights that were on my 1995 Sundowner Sunlite 3-horse slant, the holes matched up perfectly for easy installation!
by: William02/01/2018
Installation went great! I am the most satisfied with how quick the shipping was and customer service was the best! I will be using these guys for all my trailer part needs
by: Todd B.03/11/2014
Instant response following the order confirming they received it, followed up with shipping info and tracking when shipped and received it ahead of scheduled delivery! Will only use etrailer for my trailer needs.
Thanks

See what our Experts say about this Optronics Trailer Lights
- Recommended Replacement Light/Lens for an Older Reflect-O-Lite 400 the Reflect-O-Lite 400 light has been discontinued for quite a while so there isn't going to be an exact replacement. Instead, the closest replacement lens we have is the Replacement Amber Lens for Optronics MC66 Series Clearance or Side Marker Trailer Light # A66AB or the Replacement Red Lens for Optronics MC66RB Clearance or SIde Marker Light # A66RB. Both of these lenses measure 4" long x 2" tall x 7/8" deep, and is made of acrylic. There's no guarantee it'll be compatible with your...

I can confirm that the Optronics Dual Bulb Trailer Clearance and Side Marker Light - Incandescent - Oval - Amber Lens # MC66AB is 4" long x 2-1/16" tall x 1-1/16" thick with base mounting holes 3 inches on center. It is an exact replacement for Uni Bond #ML2043A, Truck Lite #26301Y, Grote #45263, Peterson #135A, and Bargman #30-58-002. The lens replacement for this is Replacement Amber Lens for Optronics...
view full answer... - Replacement Amber Lens for Marker Light on a 32 Foot Yellowstone Camino CamperI wish we had a master list of the parts used on all trailers and RVs but we do not. So we have to go by measurements or part numbers on the individual parts if applicable. The amber version of lens A66RB is # A66AB. It is a replacement for light # MC66AB which is 4" long x 2-1/16" wide x 1-1/16" deep. And that light is a direct replacement for any of the lights below: Uni Bond ML2043A Truck Lite 26301Y Grote 45263 Peterson 135A Bargman 30-58-002
view full answer... - Clearance Trailer Lights With Replaceable Lens RecommendationWe do have clearance lights that may work for you. The clearance lights we offer come in amber or red and we have either 1 or 2 bulb units. You mentioned you like the 2-bulb feature on some clearance lights. I recommend part # MC66RB. This light comes with 2 incandescent bulbs and has a red lens. The amber version of this light is part # MC66AB. Both of these lights use the replacement bulbs, part # A194B. These are push-in bulbs. The replacement lens for the red light assembly is part...

- Replacement Lenses for Unknown Trailer LampsWe have a pretty large selection of replacement lenses available. I'd be happy to look at a photo of your current lenses if you'd care to send it along. You can simply attach the photo to a reply to this email. Also helpful would be any item or part numbers printed or stamped into the light fixture itself (not the lens). Any numbers on the lens itself would be DOT certifications, not a part number for the lens. Dimensions of your current lenses would be helpful as well. I've linked you...
view full answer... - Comparing Amber Clearance Lights with 1-Wire vs. 2 WiresThe difference between a clearance light with one wire and one with two is simply that the 1-wire type uses the light's mounting hardware to establish the ground, rather than a separate ground wire. The two are interchangeable so long as the mounting surface on the trailer will allow you to drill a hole to let you attach the white ground wire to the frame. Alternately, you could attach the ground wire to another of the existing ground wires on the trailer.
view full answer... - Is railer Clearance and Side Marker Light, # MC66AB, SubmersibleThe Trailer Clearance and Side Marker Light, # MC66AB, is not a submersible light. You will not want to put this light under water. A sealed light like # MCL49AB, would be the way to go. I have included a link to a video review of this light for you.
view full answer... - Could Optronics Trailer Clearance Taillight # MC66AB Possibly Replace Lights that Hardware GroundThe simple and efficient solution would be to go with the part # MC66AB that you mentioned and if you find that the lights ground through the hardware just run the white wire back to the mounting hardware and you'd be set.

- Wiring Single Wire Clearance Lights on an Enclosed TrailerYou will need to use a circuit tester, item # PTW2993 if needed, to test the wires exiting the trailer to figure out the wiring configuration with the trailer hooked up to the truck and the running lights on. You will probably find that you have taillight power on one of the green wires and no power on any of the other wires. In this case you would wire the two green wires to the power wire coming from the clearance light. You would then need to wire the two white wires coming from the...
