Optronics Incandescent A91 Series Marker Clearance Light Dimensions

Sonically Sealed, Waterproof Trailer Light

The waterproof construction of this light makes it ideal for use on trailers that may be submerged, like a boat trailer. The housing and lens are sonically sealed together to create a single unit, which means that water will not get into the light and damage the diodes or circuit board.

PC-Rated Lights

Diagram of light spread for PC rated light

A PC-rated light produces a 90-degree angle of light to either side of its centerline for a total of 180 degrees of coverage. This beam pattern can be clearly seen when you are standing directly in front of the light, as well as when you are standing on either side of the light. When properly installed, this type of light can function as both a front clearance light and a side marker light or as a rear clearance light and side marker light.

Do you have a question about this Trailer Light?

Replacement Rear Clearance Lights For a Sure-Trac Utility Trailer ST7211HST-B-030
Based on images I could find for your Sure-Trac utility trailer model ST7211HST-B-030 it appears is uses either the Incandescent # A91RB or LED # AL91RB lights. These are held in place with the Grommet # A91GB which is 3-5/16" long x 1-15/16" wide. If you have a different style or size light please send me some images with measurements and I can verify what we have for a replacement.

Does Optronics Clearance Light A91RB with Base A91BOB Have Clearance for 90 Degree Mount
Hey Jim, yes the Mounting Bracket # A91BOB with the clearance light part # A91RB would allow a right angle pigtail like the part # A46PB to fit and have enough clearance.

Black Mounting Bracket for A91 Series Trailer Clearance Lights # A91BB Recommendation
The Sealed, Mini Rectangular Trailer Clearance and Side Marker Light, part # A91RB, that you have are self grounding. You would need a Black Mounting Bracket for A91 and AL91 Series Trailer Clearance, Side Marker Lights -Self Grounding, part # A91BB, for them to ground and function correctly. Your other option would be to run a ground wire and power wire to the two terminals of the # A91RB. However, it would probably be easier to just get the # A91BB.

Replacement 2-1/2 x 1-1/4 Inch Amber and Red Trailer Clearance Lights and Chrome Base
Based on your picture it looks like you are in need of some replacement lights and a bracket. It looks like you will need amber light # A91AB, red light # A91RB, and bracket # A91CB. And if you need the single wire (since the lights will ground through the bracket and mounting hardware) use # A91LW.

Looking for LED Version of # AL91RB Mini Rectangular Clearance/Side Marker Lamp
You bet we do! For the LED version, you'll need part # AL91RB. The lamp can be grommet mounted using # A91GB or surface mounted using a self grounding base like # A91BB for black/ # A91CB for chrome or a standard base like part # A91BOB for black/ # A91OB for chrome. If you use a self grounding base, use the single wire pigtail, part # A91LW or for the standard base, use the two wire pigtail, part # A49PB.

Replacement Trailer Taillight Recommendation for a Featherlite Utility Trailer 1693
I pulled up a picture of your Featherlite Trailer model 1693 and found that the taillights closely resemble what comes with the # TL16RK. The clearance lights of this kit are very similar to what you need as well so this would be a great starting point. For additional amber clearance lights you would need part # A91AB and then for red part # A91RB.

Availability of Red Version of # A91AB
Yes, we have the red version of the # A91AB as part # A91RB.

Replacement Boat Trailer Clearance Light with SAE P2 91 DOT on the Lens
The number on the lens that you see is the lens rating, not a part number so it is difficult to go by that number. There might be a part number on the back of the light housing. Otherwise it would be easiest to go by the dimensions of the light. For example light # A91RB does have the same lens rating. It would use a base such as # A91BB and wiring harness # A91LW for the power wire.

Trailer Clearance Light Part # A91RB Installation
To connect the Optronics Red Mini Rectangular Trailer Clearance and Side Marker Light to your existing trailer wiring, you would need the pigtail which is part # A91LW if you were using the self grounding mounting bracket, part # A91BB. If you were using some sort of other bracket that is not self grounding, a two wire pigtail is offered, part # A46PB.

Wiring Pigtail Harness for Sealed, Mini Rectangular Trailer Clearance and Side Marker Light A91RB
For a 2-prong pigtail for light # A91RB you can use # A46PB. If the bracket for the light has the ground connection in it, such as # A91BB, then you can use a single wire pigtail # A91LW.

How to Mounting the Mounting Bracket for A91 and AL91 Series Trailer Lights
I would recommend using stainless steel sheet metal screws for mounting the Mounting Bracket for A91 and AL91 Series Trailer Clearance, Side Marker Lights, since the connection to the trailer needs to make a good ground connection.

Submersible Replacement Trailer Lights for Peterson Mfg. Company PM150A and PM150B
The exact replacement for the Petersen lights you have PM150A and PM150R is the part # A91RB for red and part # A91AB for amber. These are submersible like you are wanting as well.

Are Clearance Lights Needed on a Snowmobile Trailer
To equip your snowmobile trailer with a basic lighting setup, you would need amber front side marker lights and red rear side marker lights. A basic trailer would require a minimum of two each, with the front lights as far forward as possible and the rear lights as far back as possible. The # TLK36RK trailer light kit includes the required amber front marker lights , but you could also add matching red clearance lights # A91RB with chrome bases # A91CB. I would also recommend using...
