Replacement Amber Lens for MC42AB Trailer Lights - A42AB

Average Customer Rating:  4.8 out of 5 stars   (19 Customer Reviews)

Replaces the amber lens on your Optronics MC42AB trailer light.


Was not able to find lens, in any local stores. Trailer was fitted with lights before 2006, and I thought I was have to replace all. Glad I found your web sight. Fit like a glove. Fast service too!


Great replacement,


Just what I expected. Fit better than o riginals


Needed to replace a bunch of red & amber marker lenses that were cracked and brittle on our 1975 Terry Travel Pak. These lenses were the perfect replacement, and took only moments to swap them all out.

FYI - I also replaced the old light bulbs and installed LED's. Marked improvement between the new and clearer lenses and LED's.


Good prices, good service and quality p roduct.


Excellent products, Fast delivery. Thanks George

Just like new still.

  • Replacement Lens For Double Bullseye Trailer Clearance And Side Marker Lights
    I reached out to Optronics to confirm the fit for you. The amber replacement lens for your Double Bullseye LED Trailer Clearance and Side Marker Light, 1 Wire, 10Diode - Amber, # MCL45AB, is lens # A42AB in amber but we don't have just the cover in red.

  • Do You Have an Amber Side Marker Lens for a 1977 Apache Mesa Camper
    The cover you selected for your side marker light is 2-1/8 inch tall by 4-1/16 inch wide. We have a lens that is 2 inches by 4 inches and it is the A-31AB, replacement lens for MC31AB. I could not find a reference to the part numbers you provided. If you do not believe this lens will work for your light you could purchase the whole replacement light such as the MC32AB or the 425600. These side marker lights are basically the same size as the light you mentioned and will replace the whole unit.

  • Replacement Light For A Reflect-O-Lite 300 Trailer Side Marker Light
    The Replacement Amber Lens for MC42AB Trailer Lights # A42AB is designed for the Double Bullseye Trailer Clearance, Side Marker Light, Two-Bulb # MC42AB, and will not work for your Reflect-O-Lite 300, however I have another solution. Reflect-O-Lite has been discontinued for a while now, so there are not replacement parts available, unfortunately. Instead, I recommend replacing the entire light with the Trailer Clearance or Side Marker Light w/ Reflex Reflector # MC32AB, with the butt...
