Features to know about

Brighter Light with Less Power: Dual-Diode LED Design

This small 3/4" round light packs a punch with two amber LEDs that create a smooth, bright circle of light. It draws only 0.052 amps at 12.8 volts, giving you strong visibility without taxing your electrical system. The LEDs last up to 50 times longer than incandescent bulbs, so you won’t be swapping out fragile filaments or worrying about burned-out bulbs. Once it’s in, it just works.

Ready for Wet Conditions: Sealed and Submersible Construction

You don’t have to think twice about rain, road spray, or even full submersion. The circuit board is sealed inside the polycarbonate housing and lens, keeping water from ever reaching the diodes. It’s built for environments where moisture ruins lesser lights—perfect for setups that see frequent wet conditions or launch ramps.

Compact Fit for Clean Installs: Recessed Mount with Grommet

Tight on space? This light tucks in neatly with its 3/4" diameter and 15/16" depth. It mounts flush using the included black PVC grommet and only needs a 3/4" hole. Wiring is simple too, with a 2-wire pigtail—black for power and white for ground—so you can get it connected quickly and securely.

All-Angle Visibility: PC-Rated Beam Coverage

Safety improves when you’re seen from every direction. Thanks to its PC rating, this light outputs a full 180 degrees of illumination—90 degrees to either side of its centerline. Mounted properly, it functions as both a clearance light and a side marker light, shining brightly from the front or side so other drivers can see you coming or going.

Built to Last: Solid Polycarbonate Housing and Lifetime LED Warranty

The housing and lens are made from durable polycarbonate that stands up to bumps, vibration, and the elements. With no bulbs to replace and a lifetime warranty on the LEDs, this GloLight Uni-Lite keeps doing its job season after season without demanding maintenance or attention.

Light works great. Slight difference from the factory cleat lens but nobody would notice it unless you point it out. Happy with the quality of the light. Long enough leads on the light so you don’t have to struggle with it.

All of your products were of very good quality and fit perfectly the first time. Thank you for being genuine. I especially appreciate you selling Dutton Lainson products, as I grew up in Hastings, NE. They are a very good manufacturer.

We installed these clearance lights on a 16-foot tandem axle trailer a year ago that is primarily used for hauling firewood. We use it in the forest and most of the road miles are gravel. Since the lights are not housed in a recessed light fixture, we made one of steel pipe with the leading edge extended ¼ inch to deflect flying road rocks and running through brush in the forest. All the wiring under the trailer is in conduit and all the wiring is Ancor brand marine grade. Had we installed the lights as demonstrated in a picture on the etrailer.com web site, the lights would have been damaged quickly in our service conditions. The Led lights are working fine although they run a bit hotter than preferred which may lead to a shortened life. Tip: Never use copper clad aluminum automotive wire from China on trailers as aluminum is the sacrificial metal for cathodic corrosion and the wire conductors will soon disappear into powder.

This is a tremendous wheel! The 6" wide wheel is rated at 2835 lbs. Remember your rig is only as good as its weakest link, so a pair of these would be good for 5670 lbs. Overkill on a 3500lbs axle? Maybe, but definitely gives peace of mind, and the price is comparable. They even ship with the high pressure metal stems installed. The offset is neutral, so the difference from a 5" is only a half inch back spacing increase. Be sure to check your clearances from hub face to frame, but my Dexter 95" axle has plenty of clearance from the 80" frame. eTrailer has been the best vendor, period! I originally needed these wheels in April 2016 to replace the truck wheels I had, but the 5-on-5" wheels were not a carried item. Within days the team added them to their product line and had them shipped.
These newer Vesper wheels are even better than the originals from 2016. Thanks eTrailer team for another great experience!

I would give this product a 5-star rating but unfortunately, I have had a number of these lights burn out and they are in difficult-to-access locations which makes them a hassle replacing them when they burn out. Even though they are lifetime-guaranteed by Optronics that doesn't do anything for the annoyance factor when you see one burned out and replace it, only to have another one burn out shortly thereafter. I originally bought these lights because they guarantted for life AND were very bright, even in daytime. It seems that the older version of these lights were more dependable than what they are producing now. My suggestion is that you don't hardwire them into an application-install them using individual plugs so WHEN IT BECOMES NECESSARY to replace them you will not have to keep cutting and splicing your harness each time. Other than that, they are good lights.
by:
I would like to award more than 3 stars for this product but I have recently had issues with a few of these lights burning out. Normally, they are dependable so maybe I got a bad lot of lights during my last purchase. However, I DO like these glow lights as they are very bright and noticeable even in the daytime. That said, you would think that as LEDs go they would last a long time and I do have several in use that HAVE lasted, but I also have had several that burned out fairly quickly. I am happy to report that etrailer has stood behind the manufacturer Optronics lifetime warranty and replaced the defective lights. My advice for anyone considering using these lights is to employ them in an easy-to-access application so that if it becomes necessary to change out a defective light, you will not have difficulty in accessing the defective light(s).

Easy installation and nice and bright. I have purchased two more identical lights for a boat trailer clearance lights.

These lights are totally amazing, very bright and small footprint, just need a 3/4 drill bit and they fit like a glove, will buy more for other boat trailer upgrades.
