Video Transcript for Optronics Trailer Lights A33GB Review

Today we're going to review part number A33GB. This is the Optronics grommet for the ST33 and STL33 flush-mount trailer lights. This is a rectangular black rubber grommet. It has the rounded corners for flush mounting either the ST33 or the STL33 series lights. This rubber grommet will give shock mount protection and extends the life of the lamp. Got an example here.

This is an ST33 Optronics lamp and basically what this would do when you go to install it just pops right into the grommet just like that. You can see on the very back here the grommet has an open back which allows for access to the necessary wiring to plug in and when you do install this with the light and the grommet, it does require a 3-wire plug that plugs into there. We sell two separate different, or two different ones, one is a straight. This one right here is part number A45PB and this is the straight 3-wire plug. When you plug it in you can see the wires come straight out. The other option is the A47PB and that's the right angle design. Basically that's made to when you install it you can see the wires would come out at a right angle.

Those parts are needed, or required, to install this onto your trailer. That should do it for the review for part number A33GB. This is the Optronics grommet for the ST33 and STL33 flush mount trailer lights. .

Great service! Parts ordered arrived in record time, order was complete, and no problems. I had ordered same parts from another supplier, waited 5 weeks and when order arrived it only had one light not two as were ordered. Still having issues trying to get that order resolved. You guys make it easy, will get more orders from me as well as letting my friends know where to order from. Thanks 556767

I had discontinued Command 003-5900 lamps on my trailer and these worked great. I ordered the grommet and 90 degree pigtail as well which together made it work. They are nice and bright and work as expected. Purchasing and delivery all were 100%. Exceeded my expectations. 511443

I have a flat bed on my truck and it uses trailer lights in it. When I looked for replacements all the stores wanted $10 to $30 a peace!!! Etrailer saved me almost $100 over going to may local store. I ordered it on sunday night. I had 2 personal emails telling me my order was ready and being shipped. ON SUNDAY NIGHT!!! I had my order by Wednesday with a follow up email telling me my package was waiting for me at home. My only complaint is why other online stores can provide this service. etrailer, I will be ordering again. Thank You 104385

Ask the Experts about this Optronics Accessories and Parts

Do you have a question about this Accessories and Part?


  • Depth Dimension of Optronics Miro-Flex LED Trailer Stop/Turn/Tail Light STL35RB
  • The actual depth of the Optronics Miro-Flex LED Trailer Stop/Turn/Tail Light # STL35RB is 2-5/16-inches, as shown in the linked diagram which includes overall dimensions too, but you will also need to allow for the right-angle plug # A47PB which will add another inch. This light is intended for installation using rubber grommet # A33GB.

  • What Size Hole Is Needed to Install the Flush Mount Rectangle Light and Grommet
  • The Rectangle LED Trailer Stop, Turn and Tail Light, # STL34RB, needs a hole that is 3-3/4 inches by 5-3/8 inches. This light comes with the grommet and the 3 wire pigtail for installation. There is also a right angle pigtail available, # A47PB, if space is limited behind the mounting location for the light. For a really clean looking installation you will want to radius the corners to match the corners of the grommet. I would draw a 3-3/4 x5-3/8 inch square on a piece of paper or cardboard...

  • LED Trailer Tail Light Recommendations for a Boat Trailer
  • The Sealed, Miro-Flex, Thin Line, LED Lights, # MCL63CRB, are DOT approved as Trailer Marker, Clearance or ID Lights only, so you would not be able to use them as tail lights. A similar light in shape and size that would work for you is the Miro-Flex, Waterproof, Rectangular, LED Trailer Light, # STL33RB. You would also need a wiring harness like # A45PB, and a grommet, # A33GB. Or, if a rounded light is acceptable, you can go with # STL70RB, with wiring # A45PB and Grommet # a70gb.

  • Recommendations for installing a LED Trailer Light # STL35RB on a 2002 Ranger Trail Trailer
  • This Miro-Flex, Waterproof, Rectangular, LED Trailer Stop/Turn/Tail Light # STL35RB that you referenced should work well with your trailer wiring. You will need a Straight 3-Wire Pigtail # A45PB to wire it into your trailer wiring. The red wire from this harness will run to the turn signal circuit, the black is the tail signal, and the white will ground to the trailer frame on a clean metal surface to complete the circuit. You might also be interested in purchasing a Grommet for...

  • Available Flush Mounted Tail Lights for Camper
  • We have many flush mount taillights to choose from. If you click on the provided link, you can see our selection. We have a few lamps that are similar in size to the Wesbar lamp you mentioned. The Optronics Flush Mount Rectangular Tail Light, part # ST33RB measures 5-5/16 by 3-7/16 inches. It uses a grommet mount, sold separately as part # A33GB and would require a pigtail, part # A45PB. The same lamp is available in a LED version, part # STL33RB which would use the same grommet and...

  • What Size Hole is Needed to Mount the Optronics Tail Light # STL35RB
  • With the Tail Light, # STL35RB, inside of the appropriate grommet, # A33GB, you would need a hole that is approximately 5-7/16 x 3-3/4 inches. You will also need the appropriate wiring harness, # A45PB.

  • Recommendation for an LED Trailer Tail Light
  • There is a LED light system that will work for you, but the Camping Travel Trailer Stop, Turn and Tail Light, part # RVST51, does not come in a LED version. What I would recommend you get is the Miro-Flex, Waterproof, Rectangular, LED Trailer Stop/Turn/Tail Light, part # STL35RB. It is similar in shape and performs the same light functions. It does not have the license plate bracket that part # RVST51 does though. You will also need to cut a hole in the trailer to install the Grommet...

  • Can the Miro-Flex LED Trailer Light be Mounted Vertically and Horizontally
  • As long as you have adequate room to mount the Miro-Flex, Waterproof, Rectangular, LED Trailer Stop/Turn/Tail Light # STL35RB you could mount it in basically any orientation you like. You might also be interested in purchasing a Right Angle 3-Wire Pigtail # A47PB or a Straight 3-Wire Pigtail # A45PB depending on your mounting location. Or a Grommet # A33GB for mounting.

  • What are the Dimensions of Optronics Flush Mount LED Backup Light BUL35CB
  • The LED backup light # BUL35CB is 5-5/16 inches long x 3-7/16 inches wide x 2-5/16 inches deep. You will also need a wiring pigtail, # A45CB to install this light. For a grommet, use # A33GB. I have included a picture showing the light dimensions for you.

  • Amber Trailer Blinker/Running Light Recommendation for Use on an Older Truck
  • We don't have exactly what you said you need, but the closest thing we have would be the Miro-Flex, Waterproof, Rectangular, LED # STL35AB. This is an LED amber light you could use that has dual intensity so that it can be used for a blinker and running lights. Only thing is that this is much bigger at 5-5/16" L x 3-7/16" W x 2-5/16 D. For a harness to plug into the light you would want # A47PB and then for a grommet part # A33GB.

  • Can the RV Porch and Utility Light be Used on a Camper Shell for Side Illumination for Sled Dogs
  • The RV Porch and Utility Light, # RVPL3C, would definitely be able to handle normal highway speeds, if mounted correctly, but a car wash might be a different story. These lights were designed for RVs and they are not normally ran through car washes. If the car wash were a touch-less model then you should be fine, but a car wash with the mops that twirl would most likely cause an issue with the lights protruding from the side of the shell. Another option may be to install a flush mounted...

  • What Size Hole is Needed to Mount the Optronics Tail Light # ST33RB

  • Availability of White LED-Type Rectangular Backup Light
  • For a rectangular white LED-type backup light I suggest the Optronics Flush Mount LED Backup Light # BUL35CB. This recessed-mount light uses an industry-standard plug like # A45CB and a mounting grommet # A33GB. Please click on the video link for more.

  • Dimensions and Mounting Grommet Recommendation for the LED Back Up Light part # BUL35CB
  • I attached a picture of the LED Back Up Light part # BUL35CB that shows its dimensions. If you were planning on making a grommet to install these lights you could instead just get the Grommet part # A33GB as this grommet is specifically designed to fit this light.

  • Grommet and Pigtail Needed for the Optronics Miro-Flex # STL35RB Trailer Light
  • The grommet that you will want to use to install the Optronics Miro-Flex # STL35RB is the Optronics part # A33GB. For a pigtail you have 2 different options. The 3-Wire Pigtail for Optronics Trailer Lights part # A45PB has a straight connector and the Right Angle 3-Wire Pigtail for Optronics Trailer Lights part # A47PB has a right angled connector.

  • Can Custer 4-LED Strobe Light or Running Light Be Used As A Back Up Light On 2001 28 ft class C RV
  • I would encourage installing a light that is intended to be a backup light on your motorhome. You may want to check out part # BUL35CB. This is a 16-diode LED light that is certified as a back-up light when installed as a pair. This light also requires a grommet, part # A33GB, and a 2-wire pigtail, part # A45CB. The Custer 4-LED Strobe Light or Running Light, part # STRL4A is actually designed to be a running light or a strobe light. You could attach it to the reverse light circuit...

  • Recommended Parts to Install Optronics Flush-Mount Clear LED Trailer Backup Light # BUL35CB
  • The Optronics Flush-Mount Clear LED Trailer Backup Light # BUL35CB that you referenced uses a tiny amount of power since it features high-efficiency LEDs instead of standard incandescent bulbs. Its power draw is about 1/10th that of standard bulbs, approximately 0.295-amps at 12.8 volts. This light uses a standard 2-prong connector that accepts wiring pigtail # A45CB. It mounts with grommet # A33GB. To use this as a backup light you will need to connect it to your Wrangler's reverse...

  • Can Optronics LED Backup Light # BUL35CB Be Mounted Horizontally
  • The Optronics Flush Mount LED Backup Light you referenced, part # BUL35CB can indeed be mounted onto the deck of a car trailer. The lamp is sealed, so you will have no worries about water entering the lamp housing. You would also need a grommet, part # A33GB and the wiring pigtail, part # A45CB.
    view full answer...

  • Is there a Mounting Bracket for Trailer Back Up Light # BU33CB
  • There is no bracket for external mounting of grommet # A33GB so you will have to cut a hole where you want the grommet and light to go. Use the grommet as a template to cut the hole. Start small because you can always work your way up to a larger hole if needed.
    view full answer...

  • Are Load Resistors Needed for Reverse LED Trailer Lights
  • You will not need load resistors to install the Optronics LED Backup Light for Truck or Trailer # BUL35CB; load resistors are not needed for reverse lights like these. The only thing you will need are Grommet # A33GB and a 2-wire pigtail, either part # A45CB or the right-angle pigtail, part # A49PB. I have added links for video reviews for you to check out as well.
