Greetings, I really enjoy having the trailer. We took a six day trip back in may of this year. It was great having all that room. We've also taken it on two or three day rides just in case we saw something at a craft shop or even a yard sale. Lol Each trip included a picnic lunch. I did modify the lighting on the trailer. I ride a 2014 Goldwing, and after the two, 5 to 4 wiring adapters failed I added two 3" LED turn signals near the top of the box. See photo. I may even add a third member brake/tail light to the lid rack bracket. Thanks,

Exactly what i needed! So glad I found etrailer. Not that I mind using dealers and repair shops on occasion, but I also prefer to save money on those projects that i can take on myself. The grommets were a perfect replacement and a quality product. Fast shipping was appreciated!

Have not yet had time to install the LED lighting items I recently purchased to refurbish my car trailer.

The grommet was exactly what I needed to replace the ones on my trailer. I have purchased 4 times from etrailer and every order was fulfilled accurately and quickly.

I have been trying to rebuild an old Big Tex trailer for the past month through local vendors. We needed springs, hardware, brakes, lights ect. We use this trailer for feeding cattle out on the range and the window was closing. Everytime I got a part from the local company it was wrong. Finally I found etrailer and everything was so simple to find myself and order. The service was outstanding and the delivery was a day ahead of schedule. I ordered all my suspension hardware and lights from them, it was quick and easy, quality looks great. Thank you

I have purchased from etrailer several times and I find the selection of parts very good I think their attempt to help customers with video and a good tech department is very unique and beneficial The quality of the lights I received is good but I do feel it was not the same quality as the original "Grote" brand lights my trailer came equipt with... Also the quality of the rubber grommits was definitely thinner and not as robust as all the original grommits used on the trailer originally... these parts were made over seas and the oems were all American made... This is not meant to be a "DONT BUY" I'm just stating the facts the parts are not the same quality but the price was great and the parts did work just fine but just bear in mind there is a difference but for my used trailer rebuild they were just fine the jacketed wire was top notch BTW I would buy from etrailer and these same parts again

  • Outside Diameter of 2 Inch Round Grommet
    The outside diameter of the 2" Round Grommet # A54GB you referenced is 2-3/4". This grommet is used with 2" round lights such as the GloLight LED # MCL155RB (Red) or GloLight LED # MCL155AB (Amber). You will also need a 2-wire pigtail to complete the installation of these lights; either # A46PB for a 6" lead or # A49PB for a 10" lead. I have added links to video reviews of these parts for you to check out.

  • What is the Best Way to Remove a Light From Optronics Rubber Grommet # A54GB
    When removing a light a lot depends on the space you have. If space is not an issue you can remove both the grommet and light together by pushing out from the back of the hole since the grommet would have gone in the other way originally. The light can also be pushed through the grommet from the back. Using some soapy water should help. If the connection between light and trailer is particularly tight you might not have a choice but to take both out at the same time. You would need to...

  • What Size Hole Does 2 inch Grommet # A54GB Require
    The 2" Round Grommet # A54GB is designed to be used with a 2-5/16 inch diameter hole. The light that fits down into this grommet is a pretty tight fit so if you went with a 2-1/4 inch diameter hole the light would be incredibly difficult to fit if not impossible. I'd recommend going with the slightly larger hole saw size 2-5/16 inch.

  • Replacement Side Marker Light and Grommet for a Trucklite Brand Grommet and Marker Light
    I went out to the warehouse and pulled grommet # A54GB and light # MC53AB. I then assemble them and the result looks exactly like your picture. I then measured the amount the lens sticks up above the grommet and came up with just under half an inch. The lens could be pressed further in. I used digital calipers to take the measurement. I also made a video showing the assembled result for you. The light takes wiring harness # A46PB if you do not already have them on your trailer.

  • Replacement Amber Clearance Light for Dutchman Kodiak
    The lenses on clearance lights are not generally removable as they are often "sonically sealed" such as the Optronics Trailer Clearance or Side Marker Light # MC57AB; this means they are submersible. Instead of buying a light and taking the lens off I strongly recommend an LED Trailer Clearance or Side Marker Light w/ Reflex Reflector # MCL59AB for your Dutchman trailer because an LED is a far better, much longer lasting option. You only need to make sure your existing lights have the...

    I do have options for you but we do not carry the Globrite part 9500-88-BLU. However, based on my research this light has a clear lens with an LED bulb and measures to be 2" in diameter x 1" deep. For a replacement, I recommend using the LED Trailer Clearance/Side Marker Light part # MCL55ACB for amber or part # MCL55RCB for red. This light has a clear lens with LED bulbs and dimension of 2" in diameter x 1" deep. In order to install this light you will need to use the pigtail part #...

  • What is Hole Diameter Needed to Install Miro-Flex LED Clearance or Side Marker Light
    The grommet part # A54GB that you have with the light part # MCL50RB requires a hole diameter of 2-5/16 inches. So you'd need to cut a hole 2-5/16 inch in diameter and the grommet and light will slip right in and be secure.

  • Replacement Lens Availability for Reflect-O-Lite SAE-P-P1-68
    Unfortunately we do not have any replacement lenses for your Reflect-O-Lite lights. There may be some out there somewhere but the only solution we have for you would be to replace all of your lights. If you end up wanting to do this I can help you with replacement lights but it may be worth seeing if somewhere else has replacement lenses.

  • Can a 2-1/4 Inch Hole Saw Be Used to Mount the 2 Inch Round Grommet Part # A54GB
    Yes, the 2-1/4" hole saw would be perfect for the Sealed 2" Round Trailer Clearance and Side Marker Light part # MC53RB with the 2" Round Grommet part # A54GB. This setup calls for a 2-5/16" hole but you are going to have more difficulty finding this size hole saw in comparison to a 2-1/4" hole saw. There will only be a 1/16" difference between the two so you might not even need to enlarge the hole but if you do then you can just use a file to make the assembly fit.

This light requires pigtail # A45CB or 90 degree # A49PB. If you are looking for a round light, I recommend the 2 inch # UCL50CB. This will use the same pigtail, but will use grommet # A54GB.

  • What Size Diameter Hole Is Needed to Install Optronics Trailer Light # MCL50AB
    To install the Optronics Trailer Light, part # MCL50AB, you will need to use 2 Inch Round Grommet, part # A54GB. The mounting hole to properly install the light # MCL50AB with the grommet should be 2-5/16 inches in diameter. This light uses a 2-wire plug, like the Two Wire Pigtail, part # A46PB. The Optronics Trailer Light # MCL50AB is a sealed, waterproof LED light. The advantage of an LED light is that it burns brighter than an incandescent light but draw less power. It is also...

  • Does Light # MCL50AB Use the Same Grommet as Light # MC53AB
    Yes, the Sealed Miro-Flex 2" Round LED Trailer Side Marker part # MCL50AB will fit in the same grommet as the Sealed 2" Round Trailer Clearance and Side Marker Light part # MC53AB as they are both exactly 2" diameter. The LED option however is 1-3/16" tall whereas the incandescent option is 11/16" tall but as you mentioned this should not be a problem. If you need a new grommet then you can use the 2" Round Grommet part # A54GB.

  • Will the Miro-Flex, 2 Inch Round, LED Trailer Light, # MCL50RB, Fit an Enclosed Snowmobile Trailer
    If adding the Optronics light, # MCL50RB, you will need about 2 inches of space behind your existing light for it to fit. The reason is the Optronics light is deeper including the pigtail mounting surface and the pigtail, # A86PB. If you have at least 2 inches of clearance, then this light will fit in your existing 2 inch diameter hole with grommet # A54GB. Light # MCL55RB is not quite as deep at 1 inch overall, so that is another option for you.

The hole size to mount a 2 inch round light flush mounted would be 2-5/16 inches. The grommet you would need for a 2 inch light would be 2 Inch Round Grommet, part # A54GB.

  • Drilling Out Hole to Install Sealed 2 Inch Round Trailer Clearance and Side Marker Light MC-53RB
    A 2-1/2 inch hole saw would be too large for a 2-5/16 inch hole. So I recommend going with a 2 inch hole saw and gradually enlarging the hole with either the same hole saw or a rotary tool. Then you can do some test fits with the light until you get the hole just the right size so it fits. To make sure you have the hole the right size you will want to first place it in the grommet, # A54GB, and then in the hole. Otherwise, if you just used the light or the grommet you would not get an...

  • Availability of LED Back-Up Lamp for 2-1/2 Inch Rough Opening
    If you can very slightly enlarge the hole so it's 2-5/16 inches in diameter, I have a grommet mount lamp that will work great for you. The # UCL50CB LED lamp would use the # A54GB grommet and the # A46PB wiring pigtail. The lamp isn't considered a back-up lamp, but unless the vehicle in question is a commercial vehicle that's subject to DOT inspections, it'll work great for you.
