Today we are going to show you Optronics Double Bulls Eye Trailer Clearance and Side Marker Light, part number MC42RB. Inside the light are two light bulbs for increased light output. It's a single wire design meaning we'll have a single power wire lead, and the light will ground electrically through the hardware used to mount it on the trailer. Both the bulbs and the lens are user replaceable. It's designed to surface mount on your trailer using the mounting holes that are three inches on center.
Next we are going to hook the light up to a power supply so you can see what it looks like when lit up. We'll connect our ground to the mounting hardware, and our power to the wire. Next we'll turn off the overhead lights so you can see what it looks like in the dark. And that's it for Optronics Double Bulls Eye Trailer Clearance and Side Marker Light, part number MC42RB.

4-1/16" L x 2-1/8" W x 1-1/8" D; Corrosion resistant; replaceable lens and bulbs; surface mount on 3" centers; 1-wire; 2-bulb incandescentTrailer Clearance Lights #MC42RB, easily installed, nice lights. There could be a little more space (maybe 1/8" in depth) on the backside so the wire could be positioned through an existing hole in the trailer and the light assy would sit completely flat against the trailer. Seems to be good value for the money and they are cheap.
I would recommend anyone to purchase from etrailer.com the product I received was as expected and what I needed. Price's are good the service is really good hard to find a business that cares what you get and ready to help if you need it. Also their videos are very informative if your not sure what your doing they do a very good job walking you through it. I will definitely use them again in the future.

Thank you for the concern, Everything I purchased from you are working as they should. VERY HAPPY with all.
Nothing but RAVE reviews for eTrailer.com Parts were exactly as ordered, great price, fit perfectly. Couldn't be more elated with the fast service too!
I want to keep the original look of my Airstream and the Double Bullseye lights are a perfect very cost effective replacement They add a nice new fresh look and keep the vintage appeal. I replaced all the yellow and red lights for a fresh look.
Ordered for the second time, because I didn't order enough the first time. Replacing marker lights on RV. Easy to work with, look better than current lights and are brighter. Very Pleased.
I was fixing up a vintage Shasta trailer that needed new lights and your products were just what I needed. Thank you very much for the great service.
Thanks again etrailer for a job well done. great clearance lights, fast delivery.
Third time ordering from etrailer and my experience as been perfect every time.
Great replacement light. These light are very similar to what was on the vehicle. The vehicle is a restored " Mobile Man Cave" / race support vehicle (1979 E-350 box van). I also needed a little assistance from Customer support and Cathy was very helpful. Fantastic experience all the way around. Thanks.
I used the lights on my old cub cadet tractor. Perfect replacement.

Still working fine - thanks
Replaced 40 year old clearance lights with this item. Working great after one year. Very well pleased.
OK for the price I guess.
But, boy they are very cheaply made compared to the 12 year old Peterson lights 138R lights that I had removed.
If it wasn't for the shipping costs, I would have returned them.
