Ask the Experts about this Optronics Accessories and Parts

  • 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.

  • Are There 24 Volt Red and Amber Trailer Clearance Lights
    There are round clearance lights (marker lights) that are 24 volt compatible, but the closest in diameter we have to what you are looking for is 2 inch diameter lights: - LED Trailer Clearance or Side Marker Light - Red Lens # MCL55R1224B - LED Trailer Clearance or Side Marker Light - Amber Lens # MCL55A1224B - 2" Round Grommet - Flush Mount # A54GB - Right Angle 2-Wire Pigtail # A46PB Those are flush-mounted lights but there are also 24 volt surface-mounted lights: - Optronics...

  • 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.

  • 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.

  • Outside Diameter Of The 2
    I went out to our warehouse and pulled the 2" Round Grommet part # A54GB for you. The outside diameter of this grommet is 2-3/4". As described on the product page, it is designed to house a 2" round light with a mounting hole of 2-5/16".

  • Grommet Recommendation for Bargman 2 inch Clearance Light
    The Bargman trailer light part number 41-30-002 that you referenced is a 2 inch clearance light designed to mount in a 2 inch grommet like the part # A54GB.

  • 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...

  • 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.

  • 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.

  • Recommended Rubber Mounted 2 Inch White LED Light for Reverse Lamp
    If you are looking for an oval shape, we have the GloLight LED Backup Light for Truck or Trailer - Submersible - 22 Diodes - Oval - Clear Lens - Qty 1 # BUL111CB which is rubber mounted using # A70GB. 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 Hole is Needed to Install the LED Trailer Clearance/Side Marker Light
    In order to install the LED Trailer Clearance/Side Marker Light part # MCL55AB you will need the Flush Mount 2" Round Grommet part # A54GB and the Right Angle 2-Wire Pigtail for Optronics Trailer Lights part # A46PB. Once you have acquired these items the rubber grommet will require a 2-5/16" diameter mounting hole to install. I have attached an installation video of the rubber grommet for you as well.

  • Replacement Alternative for the Globrite Part 9500-88-BLU
    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...

  • 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.

  • Recommended Red Clearance Light to Match Amber Clearance Light
    I believe you are looking for the Sealed, Miro-Flex, 2" Round, LED Trailer Side Marker, Clearance or ID Light, 9 Diode - Red # MCL50RB to go along with the Sealed, Miro-Flex, 2" Round, LED Trailer Side Marker, Clearance or ID Light, 9 Diode - Amber # MCL50AB for your trailer. You will also want the Right Angle 2-Wire Pigtail for Optronics Trailer Lights - 2-Prong PL-10 Plug - 6" Lead # A46PB and the 2" Round Grommet - Flush Mount - Open Back # A54GB for this installation.

  • 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.

  • 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...

  • What Is Hole Size For Mounting 2 Inch Round Trailer Lights With Rubber Grommet
    The item you selected, Sealed 2-1/2 Trailer Light, part # MC57AB, is a 2-1/2 inch light that will mount into a 3 inch hole using 2-1/2 inch grommet, part # A55GB. 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. If you are flush mounting your lights, the 2 inch light will sit inside the grommet. A 2 inch light similar to the one you selected is part # MC53AB. We...

  • 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...

  • What Size Hole is Needed for Installation of 2 inch Round Trailer Clearance Light MC53RB
    You will need to cut a 2-5/16 inch mounting hole for installation of the 2 inch Round Flush Mount Grommet, item # A54GB, and the Sealed, 2 inch Round Trailer Clearance and Side Marker Light, item # MC53RB. The proper wiring pigtail for this light is the Two Wire Pigtail, # A46PB.

  • 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.

  • Availability of LED Amber and Red Clearance, Tail Lights, and Side Marker Trailer Lights
    The STL42RB does come in amber. It is # STL42AB. Use wiring harness # A45PB with it. For 2 inch diameter amber lights you can use # MCL50AB with # A49PB and # A54GB. For 2 inch diameter red lights you can use # MCL50RB with # A49PB and # A54GB. For amber teardrop lights, you may be able to use # CBL22AB. We also have a teardrop shape kit that you would use on the roof of a truck, # CB-15AK, but it is not LED. For red teardrop lights we also do not have an LED option but we do...

  • Tail Lights and Clearance Lights that Can be Used on Both a 12 Volt System and 24 Volt System
    For a tail light that can run off of 12 volt or 24 volt systems you can use Transit tail light # STL90R24B. For clearance lights you can use # MCL55A1224B for an amber light that works with 12 and 24 volt systems or # MCL55R1224B for a red light. For these lights use pigtail # A46PB and grommet # A54GB. Or for surface mount clearance/marker lights that are 12-24 volt compatible you can use # MCL66A24B for amber and # MCL66R24B for red.

  • Recommended Miro-Flex Clearance Lights With Clear Lens For Trailer
    We do offer Miro-Flex lights with clear lens for your trailer, but none of the Miro-Flex lights we carry are round with clear lens. The lights I recommend with a clear lens are part # MCL-50CRK. These lights have 3 LED diodes and come with the plug and grommet needed to install. For a round 2 inch Miro-Flex light, we offer the amber light, part # MCL50AB and the red light, part # MCL50RB. To mount these lights you would need the rubber grommet, part # a54gb, and you would need...

  • What is the Minimum Depth Required to Mount Optronics Clearance Light # MCL50AB
    With the Optronics light, # MCL50AB inserted in the grommet, # A54GB, and the wiring harness plugged in, # A46PB, from the back of the grommet where it will be touching the trailer, to the back of the plug it measures 11/16 inches. A depth of 1 inch would probably work well.

  • 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 LED Trailer Clearance/Side Marker Light - 4 Diode, 12.8 Volts - Round - Amber # MCL55A1224B will have an orange/yellow color. They do have a darker amber lens than some other options on the market. I've attached a video to assist. They will ship from our warehouse in St. Louis area (Wentzville). I've attached a review and an installation video to assist. These lights will use grommet # A54GB and wiring pigtail # A46PB or # A86PB.
