Every original grommet (14) on my 2017 motorhome was brittle, broken or cracked in halves. Hopefully these will last more than a few years. They are an exact looking replacement, they need to be warm to be able to stretch over the light bulb. I removed the old grommet, warmed the new ones in hot water, stretched them over bulb and inserted into hole of bezel then carefully pressed bulb into grommet until seated. I had ordered one extra to have for a backup, ended up using it as one grommet was a manufacturing defect (short shot). 789906

eetrailer is my go to for trailer parts. The chat is a great plus. They didn't have everything I needed but can't fault them for that. Their prices for rear marine trailer lights seemed high so I got them elsewhere. Did not stock push pull-ties for my trailer so I got them elsewhere. 762322

everything works great thanks Jack 617071

What more can I say about these grommets that hold the light pods in place? They are necessary if using the round LED lights. My only comment is that I would like to see them made from a softer type of plastic to make it easier to insert into the application because the plastic composition is stiff and not very pliable. 599616

Had to replace this grommet on the 14 LED lights on the front of our 2016 Bounder. They were the exact item and saved us a lot of money. That is because a dealer told me I would have to buy the entire light, that would have been 14 x $13 each. This is the third time I have purchased something from etrailer and every time it has been at a fair price, delivered in a timely manner and been of good quality. 540086

I bought this because it was recommended in the video for installing a brake controller in my Toyota Highlander. I should have looked at the details more closely, because it is way larger than needed for the application. I don't like drilling huge holes in my vehicle's firewall. I think something like the SWC8055 would be more suitable. 529303

  • Best Place to Drill or Run Wiring Through the Firewall on a 2014 Jeep Cherokee
    The ideal thing to do when adding wiring to any vehicle would be to use existing holes already made in the firewall. If you do not have any existing holes then you will want to drill in a place that is close to where you are needing to run the wire. Be sure to check the other side of the firewall before drilling so that you do not drill into anything on the other side. Make sure to run the wiring away from where feet could get caught or wrapped around the wiring. If you do have to drill...

  • Trailer Hitch and 7-Way Wiring Connector Installation on a 2004 Jeep Grand Cherokee
    The hitch that you referenced the Curt # 13051, is indeed a class III hitch that is confirmed as a fit for your 2004 Jeep Grand Cherokee. I have included a video of this installation for your reference. Since your Cherokee does not have any existing wiring harness you are again correct that there are several plug in applications that will establish a 4-way trailer wiring harness for your vehicle. To install a fully functional 7-way connector for your Jeep you will have to start by establishing...

  • Needing a 2-3 Wire System that will Seperate the Turn Signals from Stop Signal
    I do have a part that will work for what you are needing, but the Hopkins Tail Light Converter Kit, part # HM48895, will not take a 2 wire signals and split it into a 3 wire signal. To split your 2 signals into 3 you will want to use the Tow Ready Vehicle to Vehicle Tail Light Converter, part # 118158. This will take your combined turn and stop wires and separate them into right turn, stop, and left turn wires. Please note that this converter does not work well with LED lights. Another...

  • Will Optronics Oval Reflector For Uni-Lite Trailer Lights Work With Grommets On Uni-Lite
    The Oval Reflector for Optronics Uni-Lite Trailer Lights, part # A11RXB may work well for your lights, even with a grommet like part # A11GB. I have attached a couple of photos that show the dimensions of both the # A11RXB as well as the # A11GB. The outside dimension of the #A11GB measures just over an inch. The recessed area on the back side of the # A11RXB measures 1.1 inches, and is .16 inches deep. The hole in the reflector measures 3/4 inch across so the Uni-Lite like part...

  • Should the Power Wire for the Curt # C56387 be routed Inside or Outside on a 2018 Chevy Malibu
    Typically the power wire for a wiring harness like the T-Connector # C56387 that you are installing on your 2018 Chevrolet Malibu is routed outside and under the vehicle. If you can locate a grommet like part # A11GB at the rear of your vehicle you can then route the wire outside without drilling through your Malibu. Be sure to seal it back up with a gasket maker like part # LT37467. Once outside we usually try to route the wire through the frame as that will keep it protected pretty...

  • What is the Difference Between the Optronics Uni-Lite Clearance Lights MCL12RK and MCL12RKB
    The difference is the grommet part # A11GB. The # MCL12RKB comes with it and the # MCL12RK does not. You should note that we do not carry the # MCL12RK.

  • What is the Outside Diameter of the Hopkins Molded Trailer Wire Connector Part H20046
    I went to our warehouse to get the Hopkins trailer wire connector # H20046 to provide you the measurement you requested. The outside diameter is 0.61 inches using a digital caliper. A rubber grommet you should take a look at is the Optronics flush mount rubber grommet # A11GB. I went to our warehouse again to measure the inner and outer diameter. The inside diameter is 0.61 inches but can stretch to 0.74 inches. I think this would be perfect for what you are needing. The outside diameter...

  • Wiring Installation Into the Custer Light Mounting Box # AL65-02
    For the Custer Light Mounting Box - (2) 6-1/2" Long Oval Holes - Diamond Plate Pattern - Aluminum # AL65-02, you will use the PVC Grommet for 6-1/2" Oval Trailer Tail Lights # A70GB with lights like # STL22RB or # STL22AB. These lights use a pigtail like # A47PB or # A45PB. You will need to drill holes in the housing to mount and add a hole for the wiring as well. I recommend using a the Snap Bushing Grommet - 7/16" ID, 9/16" OD # SWC8055 or the Replacement Flush Mount Rubber Grommet...
