• Difficulty Installing Optronics Market Light MCL157AB and Grommet A55GB in Bracket BK55BB
  You are not alone! The lights # MCL157AB have to fit tight in the grommet # A55GB and the grommet in the bracket # BK55BB so there is very little tolerances. One thing that I have had success with is to put the light in the grommet and then push both into the bracket together. Another tip that usually does the trick is to use some soapy water on the outside of the grommet to help it slip into the bracket.

• Clearance Light Recommendation for 2-1/2 inch Hole In Flat Bed Truck
  We have 2-1/2 inch clearance lights but they require a 3 inch hole for the grommet like part # A55GB to install. For that you'd want the part # MCL51RB. The next size down is 2 inch but the hole required is 2-5/16 inch which wouldn't work for you.

• Does Metal Mounting Surface have to be a Certain Thickness to Use 2-1/2 Inch Round Light Grommet
  Metal that is 1/4 inch thick will work well for the round grommet # A55GB. There isn't a specific metal thickness requirement for the grommet since the light pushing against it when installed is what holds the whole assembly in place.

• Looking for Trailer Clearance/Marker Light to Replace Trucklite Model 10
  According to my research, I have found that the Trucklite model 10 clearance/side marker light measures 2-1/2 inches in diameter. Because the Optronics # MC53AB measures 2 inches in diameter, it would not be a good replacement. The Optronics # MC57AB, with its 2-1/2 inch diameter, would be the correct replacement. If you need a mounting grommet, it is available as part # A55GB. The two pin wiring pigtail is also available as part # A46PB.

• How to Route Curt T-Connector to Trailer Hitch on a 2018 Honda CR-V
  To route the Curt wiring connector # C56370 permanently to your trailer hitch you need to look for any grommets around where your spare tire is stored.

• Can Optronics Sealed 2-1/2 Inch Light be Mounted in a 2-7/8 Inch Hole
  In order to install this light, you will need a grommet to fit the hole. We have a grommet for a 2-25/32 hole, which is just under 2-7/8 as well as a grommet that fits a 3 inch hole. If you can re-measure the hole with something that has 16th inch or 32nd increments we can get a more accurate measure of the hole. If it is a 2-25/32 inch hole, you would use grommet # A57GB. If you find it is a 3 inch hole, you can use part # A55GB. Both of these grommets will work with the MC57AB.

• Replacement Clearance Light with a Reflective Lens for a Horse Trailer
  The Optronics light, MCL71AB, does not have a reflector in the lens. I made a short video that shows the light with the lens off. It would be a fairly water resistant light. A better option may be # MC35AB. It is about the same size and it has a reflector in the lens. It is not as low profile as the flush mount light you referenced.

• Replacement Clearance Lights for a 1977 Rancho El Rae Camping Trailer
  Unfortunately even with the mounting dimension it will be difficult for me to recommend a replacement lense cover for a trailer that old without knowing the brand and model number of the lights you have installed. Therefore, I recommend replacing the lights on your trailer with a set of new LED lights that way you will not have to worry about them for some time. For the circular lights on your trailer I recommend using the LED Trailer Clearance/Side Marker Light part # MCL57RB for red...

• Replacement Red, Round Side Marker Light for a 2010 Triton Trailer
  The SAE AP2 98 on the lens indicates the lens rating but it isn't a part number. Light # MCL59RB is 2-1/2 inches in diameter and takes grommet # A55GB and harness # A46PB. But none of the clearance lights we have that are round and 2-1/2 inches have the same lens rating.

  You could route the 4-Way connector on the T-One # 118469 through the floor of the trunk on your 2007 Nissan Quest.
