Replacement Red Lens for Peterson 3-3/4" Round Stud Mount Tail Lights - 420-15

Average Customer Rating:  4.9 out of 5 stars   (101 Customer Reviews)

Replaces the red lens for your 3-3/4" round Peterson stud-mount tail light. Fits 428 series lights. Screw-on.


Perfect replacement lens!


Just what I needed for my trailer. I do wish it would have come with screws though. Now I have to do research as to the size I need.


Works great on my ‘67 Ducati


Perfect! Great product at a great price. Believe it or not these perfectly fit the 3-3/4 inch tail light on many vintage Italian motorcycles ( Moto Guzzi, Ducati, Benelli, etc.). They are a great replacement for the original CEV lenses. They obviously don't have the tiny original CEV letter stamping but the look and fit is excellent.


Replaces the taillight lens on my 1973 Moto Guzzi Eldorado nicely.

It still looks great!

thanks quick delivery and right price


Excellent. I have an old Piaggio ciao (Vespa) moped that had a cracked Original tail light and this fit perfect. I may have to purchase another one in the future.


Exact replacement for my boat trailer. Reasonable price as well.


Got what I order right on time


Fits perfectly fast shipping


The lenses fit perfectly. They work very well and allow the lights to function properly. It would’ve been nice, if the red color was a deeper or darker shade of red. I really prefer a very dark red taillight color, but this would be considered normal.

Tail lights working fine after one year. No problems!
Mark F - 08/31/2019


etrailer was the only place that I could find the exact lens that I needed. The price is great. I have a homemade car hauler trailer and the rear lights are too low. I keep breaking them. Fast shipping also.

No issues. Will use you guys again when necessary. Takecare.
Gerard B - 09/23/2016


This was a straight forward replacement of old crack trailer lens. The only issue I had, it took 11 days for the item to get to my house. Anyone could have just dropped these at the post office and within 4 days been at my house. I really like etrailer and their prices, but small items like this, dude just drop it in the mailbox.

Excellent still as bright the day I bought them.
Ken R - 10/08/2018


Great price, fast shipping, just what I needed. Thanks again!


The PETERSON ROUND RED REPLACEMENT LENS 420-15 were high quality and arrived promptly. These will be used on my utility trailer. This is a 5 star honest merchant.

great. still a good product.
Russ L - 10/22/2017


Exactly what I needed for my trailer. etrailer was the only company that I could find that still carries the exact lenses for my old trailer. Thanks!

Still working well ...
Mike E - 06/13/2017


Recently I was bummed to discover that my beloved TAB teardrop trailer was missing one of it's vintage looking tail light covers. The manufacturer quoted me nearly $50 to replace the entire light with a newer design. Ericka B. at helped me find the exact replacement part (the cover only). I splurged, bought two, and they shipped in no time. I installed them in minutes. I am thrilled to have discovered etrailer for hard to find replacement parts. Excellent customer service, invaluable products to keep fun trailers looking smart.


I had a small order of one tail light lens, but I was treated like I ordered a dozen! I received order confirmation, updates, and tracking information. The shipping was quick, and the packing was first rate. In fact, the whole experience was first rate. This lens was not available locally or on line, but came up with the goods.It matched the original exactly. I will continue to order exclusively online from them because....hey, the price is right and they get it to you quick. Very pleased with the whole deal all around. Thanks.


The lens were a direct replacement for my trailer taillights, This was good finding them at since none of the local auto parts stores had them.


Broke the Lens on my old trailer. None of the local trailer places had it in stock, in fact the guy told me that I would be better off going to a car place and trying to match it up with a tail light lens????? Once again, I turned to etrailer and found what I needed. Exact match!!!!
Fast shipping and excellent communication. Very satisfied. Thanks


I needed new lenses for my trailer brake lights.. NAPA didn't have them... but easily found at etrailer... they sent them right away... saved me replacing the entire light fixtures on both sides of my trailer... thanks again


I have restored a 14' 1951 Canned Ham travel trailer. I needed to replace the tail light lenses. These Peterson lenses were of better quality than the ones I took off. I couldn't be happier unless I found a can of gold coins in my yard....


Easy access to web site, easy ordering and shipping that doesn't cost an arm and a leg .I was very happy with notifications and tracking information. One of the best experiences I have had ordering on line. These people have customer service at a new level. Product is as good as the service!


I broke the tail lenses on my tractor. These replaced the broken lenses perfectly. Much more reasonable price than the dealerships parts.


Was so glad I found this site for parts! their prices are reasonable and they did not try and take advantage of the buyer with ridiculous shipping costs. I got my order very quickly. I will come back again!!

  • Replacement Round Red Lens Needed for Lights on Reese Outfitters Adventure Bike Rack
    I spoke with my contact at Reese who said that they don't have any specs for the kit 09003 that you referenced because of how old it is. We do have a wide variety of replacement lens though so if you could take some measurements and let me know the dimensions of the lens I can see if we have any that would be compatible. If you have some pictures of the lens that would help as well.

  • Replacement Round Tail Light Lens for 2017 Entegra Aspire Motor Coach
    Luxury coach maker Entegra's part number 0282193 for the light lens you need appears to be their internal reference since I could not find specifics by searching on this number. I reviewed photos and videos of the 2017 Aspire and I noted the unusual tail light design. I linked a photo to show what I found online. The round red lenses appear to be about 4-inches in diameter. We carry a range of such replacement parts that appear on the linked page, such as Peterson # 420-15 which is 3-3/4-inches...

  • Replacement Lens for Trailer Tail Light
    We may have a lens that will work for you, though I could not find a reference to part 16PS2T2. We do have replacement lenses for tail lights such as the Red Replacement Lens for Peterson Pedestal Mount Tail Light # 338-15R or Replacement Tail Light Lens for Optronics # A40RB that are round and 4-1/4" diameter. The only one that is smaller is the Peterson Red, Round Replacement Lens # 420-15 which has a 3-3/4" diameter.

  • LED Replacement for Peterson 420-15 Trailer Light
    I do have an option for you but the GloLight LED Trailer Tail Light part # STL101RB most likely won't fit into the mount you have welded to your trailer. The actual outside diameter of the light is 4.25". The recessed portion behind the lens on the base is around 3.80" which I think is what you are asking for so I went out to our warehouse to confirm this for you. If you need to replace the light you have now then you can use the Peterson Round Trailer Tail Light part # 431800 or part #...

  • Recommended Tail Light Replacement Lens for Vintage Glass Lenses
    If you just want a lens, I recommend the Peterson Red, Round Replacement Lens # 420-15 which measures 3-3/4 inches diameter and has two holes for mounting screws. The only other options we have are the Replacement Tail Light Lens for ST24RB and ST25RB # A24RB which measures 4-1/4 inches in diameter. The The Optronics Red Replacement Tail Light Lens for ST51RB and ST52RB # A52RB is a 4-5/16 inch diameter red lens. Either one would need to be sanded down for the proper fit in your custom...

  • LED 1157 Light Bulbs For Converting Peterson Trailer Tail Lights 432000 & 431800 From Incandescent
    I recommend replacing your Incandescent Bulbs # DI79VR on your Peterson Tail Lights # 432000 & # 431800 with LED Bulbs # CM93236. There is currently not a LED light that will bolt in place of your current Lens # 420-15 on your tail lights. These LED bulbs have a 2,000 hour bulb life.

  • Is Peterson Red Round Replacement Lens # 420-15 Interchangeable with DZ 77-845 Tail Light
    The Peterson Red Round Replacement Lens, # 420-15, is not interchangeable with the DZ 77-845 light that you referenced but I may have a solution. For just a bit more than the cost of a lens, you could replace the entire light assembly with the Sealed, 4" Round Trailer Stop, Turn and Tail Light, # ST45RB. 3-Wire Pigtail, # A45PB, and Rubber Grommet, # A45GB, would be needed in addition to the light. Unfortunately we do not offer a replacement lens that will work for your current light.

  • Round 3" or 4" Red Lens Needed for Model Railroad Crossbuck Sign
    The replacement tail light lens # A52RB is for the lights # ST51RB and # ST52RB which are larger than 4" with a 4-5/16" diameter. For your application we have the Peterson Lens # 420-15, with a 3-3/4" diameter, or the Optronics # A20R, which has a 3-7/8" diameter.

  • Replacement Round LED Trailer Tail Light for a Peterson Round Tail Light
    The Peterson part number # 420-15 that you referenced is a replacement lens for the Peterson Round Trailer Tail Light # 431800 which has a 3-3/4" diameter. Although we don't have an exact match to this in LED we do have slightly larger sizes of round tail lights that come as LED. If you are wanting to go with one from Peterson then we have the LED Trailer Light # M826R-7 which has an overall diameter of 5-1/2" but the light diameter is only 4-1/4".
