Video Transcript for Optronics Accessories and Parts A70GB Review

Today we'll be reviewing part number A70GB. This is the Optronics Rubber Grommet for 6 1/2 inch Oval Trailer Lights. It is designed for flush mounting those lights. It's going to provide shock protection. This is going to extend the life of your lamp. It's going to feature that open back design that's going to give easy access for wiring.

This does require a 3 wire plug along with the lights to complete installation. Those are going to be sold separately. Couple different plugs that we would recommend is part number A45PB or A47PB. Let's go over the dimensions of the grommet. It's going to give us an overall length of 7 5/8 of an inch. Overall width of 3 3/8 and then an overall depth of 1 1/8.

That's really easy to install, a light I have in right here for our demonstration. Once you have your 6 1/2 inch over light, all you got to do is place it through the grommet. Then just push it into place. The grommet comes up over the light and that's all there is to it. The light is nice and secure in there.

Again, you have the open back for easy access to the wiring. That going to do it for today's review of part number A70GB. This is the Optronics Rubber Grommet for 6 1/2 inch Oval Trailer Lights. .

Didn't fit the holes in my trailer, although LED lights fit and were same size as original. Measure the cut out in your trailer before ordering. Product was fine but my assumption was it was a standard size. My fault - they will go in the trash now. 79286


I just had the same experience, needed a thicker or bigger gasket, even trailer manufacturer confirmed this issue, not sure where to get the thicker gasket from? Like You, I thought these were all the same size, the lights to go into the gaskets are...but not the gaskets?

comment by: todbnla - 05/20/2013


Do you have the part number from the old gasket? Should be molded on it somewhere. That may help shed some light.

I ordered two new lights for my boat trailer and two new rubber grommets to go with them. The rubber grommets were too small and the light and grommet would fall out of the hole. I ended up using my old grommets with the new lights. They were very inexpensive but worth zero. 187798

by: Nathan C.09/30/2013

This is a really nice quality grommet that works perfectly with the Optronics series of lights. You cannot beat the price on these - it makes reusing the old ones silly because you will inevitably tear, stretch or otherwise destroy the old ones taking the lights out. 102047

by: shawn b.04/08/2013

Product is good quality and was shipped quickly - only issue I didn't measure well enough and the grommet is about 1/4" too small. But that's my own fault! 75005


Theyre still going great so far. With trailer lights up here I need stuff thats durable. So far so good.

Its a rubber grommet. It holds the light in nice and tight. Not much else to say besides they're priced cheap and a whole lot better than the sun rotten ones I just threw away. Not quite as thick as the original, but who cares,its $0.95 and works! 101749

  • How to Remove Flush Mount Taillights and Grommets in a Square Tube Snowmobile Trailer Frame
  • It sounds like your trailer has the 6-1/2 inch Oval stop turn and tail lamps and some side marker lamps that use a rubber grommet like the 6-1/2 inch oval tail lights grommet, # A70GB. Since the area where your lights are mounted is not accessible from the back side, you will need to pry the light out of the front of the grommet with a small screwdriver or other similar tool. If you could find a plastic pry tool that might work better and keep you from damaging the rubber grommet. Another...

  • How to Cut a Grommet Hole for Installation of the Oval Trailer Tail Lights # STL22RB
  • The easiest way to cut the oval hole for the Rubber Grommet, # a70gb, in my opinion, would be to use a Light Mounting Bracket for 6-1/2 inch Oval Trailer Lights, BK70BB, as a template and then use a hole saw the correct size to cut a hole on each end of the mounting location. Then, use a angle grinder with cut off wheel or a reciprocating saw with metal cutting blade to cut the straight top and bottom sides of the hole. The correct width for the grommet is 2-5/8 inches, but I have found...

  • Which Trailer Wiring Connector Has a Pin for Reverse Lights
  • In order to add reverse lights to a trailer would would need to have a 7-Way on the trailer, like # 50-67-008, and a 7-Way on the vehicle. On the vehicle side, if you are looking at the back of the 7-Way where the wires connect, the reverse light circuit is the center pin. It will need to connect to a reverse light wire behind one of the vehicle tail lights. On the trailer side the matching pin is again the center pin. So from that pin, you would route wire to reverse lights. Reverse...

At that point, you will have a fit tight enough that the lamp is securely held in place.

  • The # STL72RB tail light would use a 3-wire plug, like part # A45PB, which would have a white, a black, and a red wire.
