Optronics BUL43 Series LED Utility Light

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.

Well the good news here is that the LEDs come with a lifetime warranty through Optronics. I will have our customer service team reach out to you.



by:

These lights are exactly as advertised. They were a perfect match to the non-led lights I was replacing. They provide an amazing amount of light and the install was simple. I would definitely purchase these lights again.



by:

This product has proved very durable to the environmental effects. They are used as ground lights for our fire apparatus and withstand the road grime they are subjected to, especially during the winter season.



by:

Used these as backup lights on a stock trailer. Brighter than I expected!



by:

The light has performed very well for the application. The price is reasonable.



by:

etrailer will always be my go-to. Easy online ordering the customer service is first class. I wish more online retailers would have the same go to market attitude.



by:

Works great for our application, going on a truck for backup light. Hopefully will be nice and bright when installed. Customer service A+.



by:

This is a really nice product! The simplicity of mounting along with the very low current draw opens up a ton of switching options.



by:

Great product couldn't find locally took a chance and what I got was outstanding. I installed them the next day and was on the road in 30 minutes. Very bright lights



by:

We received our order as promised. The products were of good quality for a fair price. We will order again.

See what our Experts say about this Optronics Work Lights

  • Compatibility of High-Efficiency LED-Type Exterior Trailer Lighting
    An individual LED type light may not put out as much light as certain individual halogen lights do, but because, as you noted, LEDs use so little power you can use more of them. You could potentially BOTH increase your overall light output and still save power, leaving more of the generator's capacity to operate other devices. Another advantage of LED lighting is reduced waste heat (a result of the LEDs' efficiency). The linked page displays all LED type trailer utility lights. These include...

    The Peterson Trailer Tail Light - Weatherproof - Stop, Turn, Tail - Incandescent - Round - Red Lens # M426R is 4-1/4 inches diameter and using a grommet that fits the 4-1/2 inch hole. With this same grommet you can use the Peterson LumenX LED Trailer Tail Light - Weatherproof - 7 Diodes - Clear Lens # M826C-7 which has a 1200 lumen output. The GloLight LED Backup Light for Truck or Trailer - Submersible - 21 Diodes - Round - Clear - Qty 1 # BUL101CB has 326.4 lumens. The Optronics LED...

  • Light Output of Optronics # BUL43CB Trailer Lights
    For the most part, Optronics uses Candela rather than Lumens to measure the output of their trailer lamps. The Optronics # BUL43CB light output is 310 Candela. At a distance of 1 foot, Candela is equal to Lumens. You might also need a pigtail, like # A47PB or a mounting grommet # A45GB.

  • Replacement 4 Inch Reverse Lights to Replace Truck Lite Stop Turn Lights
    If the cut out diameter of your vehicle is 4-1/2 inches then you can install the part # STL55RB in place of what you have with the grommet part # A45GB. For a similar clear version of this light you would want the # BUL43CB.

  • 4-Inch Round White LED Work Light to Fit Rubber Grommet A45GB
