Upgrading from incandescent lights makes a big difference in brightness and reliability. This Thinline LED clearance or side marker light uses 4 diodes that shine bright while only drawing 0.06 amps at 12.8V. It’s a low-profile, energy-efficient design that runs cool and doesn’t burden your electrical system. With no filaments to break, the LEDs last up to 50 times longer than traditional bulbs—so you can forget about constant replacements and just enjoy a sharp, even red glow every time you flip the switch.
When space is limited, this light fits right in without sticking out. Measuring 3-15/16" long x 1-1/4" tall x 7/8" deep, it mounts cleanly on surfaces with holes spaced 3" apart on center. The Thinline Series design keeps things streamlined, making it easy to place along rails or narrow corners where bulkier lights just won’t do. It accepts industry-standard 1-prong or 2-prong plugs for a simple connection to your existing wiring setup.
Water intrusion can kill most lights, but not this one. The lens and housing are sonically sealed into a single waterproof unit, keeping moisture out even when fully submerged. That means you can count on the LEDs to stay protected from dirt, road spray, and full dips in the water—perfect for trailers that face rain, washdowns, or launch ramps on a regular basis.
You can install it exactly how you need with its flexible mounting system. It surface mounts using an open-back or self-grounding bracket (sold separately) like the A65PB in black or A67CB in chrome. The design grounds through the mounting surface for an easy single-wire setup—no extra ground wire needed when mounted to metal. The bracket holes are 3/16" in diameter, so standard 1/8" screws or rivets work perfectly to hold it secure without hassle.
This light’s P2 rating gives off a focused 45-degree beam to each side of center for a total of 90 degrees of coverage—bright enough to catch attention straight on but without glare from wide angles. It works great as either a clearance light or side marker light when properly mounted, providing dependable visibility that meets safety standards and keeps your trailer easy to see at night or in low light.

Nice retrofit for old thin-line bases, they work - they aren't super bright, but trailer already had screw holes and bases, so it was easy replacement especially where they are molded around in fiberglass bulkhead on an older cargo trailer. for what it is, I think they're a little pricey, doing a whole trailer with them would've gotten expensive
All items match the old units and fast shipping makes
for a great experience---very helpful staff.
Thanks
I ordered all LED lighting for my Haulmark motorcycle trailer because the OEM lights faded out in a few years. Replacing with all LED's on the marker, tail and tag light will reduce power draw and make my trailer even more visible. Thanks eTrailer.com for the fast delivery and easy to navigate website but most of all the excellent prices.
We have a 7x14 low rider trailer and replaced all lights and marker lights with LED lights. The figment was perfect and they look much better than original lights.
I cant tell you how disappointed I am...........that I did not find out about etrailer.com until now. The LED marker lights that I installed on my Haulmark Lowhauler are simply amazing. They are brighter than the big name companies truck lites out there that I had bought. It is too late for me to return my other lites but I went ahead and changed all the lights on my Nautique boat trailer with your products. It is the difference between night and day. Thanks for the great products. You have gained a NEW LOYAL customer. Speaking of that... I placed another order today. Thanks again!!
I bought the series of thin line replacement lights for my 2005 Haulmark trailer. They fit and worked perfectly, are as visible as the originals (with restored color as well - the old ones were sun-faded) while drawing much less power.
Now the 5 amp fuse that most cars have for a tail light will safely run all of the tail, clearance, and interior lights on the trailer without blowing the fuse.
The first time I plugged in the trailer with the original lights it blew the fuse (without even the interior lights on).
Buying these lights was the perfect solution. Now any flat 4-wire plug on any car can be used to operate the trailer.
Easy install. I bought all new LED lights for my Haulmark trailer and was ready for the road in minutes. Thanks!

Great Products at a great price. My local store wanted to charge me more than twice the price I was able to purchase from you.I will purchase from your company within the next two months. I have additional lighting requirements for my trailer.
Upgraded all lighting to LED lights on 2006 Haulmark utility trailer. The new LED lighting provides highly visible safety clearance lighting for night and day use. etrailer website is easy to use, my orders were quickly filled and promptly delivered. Good job!
Excellent products. These lights work perfectly, are rugged and seem to last. The license plate lights are super bright so law enforcement have no problem reading the plate which avoids unnecessary stops. The lights are directs replacements as well so no modifications needed. Great products. I recommend etrailer to many of my friends and colleagues.
Great replacement parts for my enclosed box trailer that was damaged in the Camp Fire in 2018. The trailer held up pretty well but the marker lights, tail lights and fender lights all melted during the fire. These were perfect replacements and mounted very easily.
I was so ready to go to LED lighting for my trailer. I also found the website very user friendly,was able to quickly find and choose exactly what I wanted and a very reasonable price.,will definitely be using the site for more purchases.
Thanks to all the staff

Product is doing great,,thanks
Exactly what I received great quality would recommend
The items I ordered came quickly after I placed the order. Replacing the old lights with the new LED lights was easy and it made a big difference in making the trailer easier to see not only at night but seeing the brake lights in the daylight hours. The roof hatch was a easy replacement for the original one. I know the metal one won’t crack and break like the plastic one that was original equipment. After investing in a trailer to haul the hot rod that has taken years to build, make sure the other guy that’s not paying attention can see you and your investment
I replaced all the marker lights on an older enclosed trailer. Easy and looks great. No more loose blown bulbs. Thankyou
Perfect fit on my CargoMate trailer, really bright, fast shipping and great price.

Still working as expected and still very bright, great product
Poor/incomplete product description. These are obviously replacement lamps for some type of fixture. These are not meant to stand alone with wire pigtails that you can use to replace existing trailer lights. I'll have to return these now.

As mentioned in the product description above, the lamps are mounted using the pigtails and surface or grommet mounts which are sold separately. These items arent included because the mount and pigtail needed will depend on how youre mounting the lamp.
Not my first order from etrailer and definitely not my last. My only complaint would be in the packing of small or fragile items loosely in a box with heavier items. One of the trailer light mounts was broken when it got here. No other issues though.

We do our best to package our orders so that they will arrive to you in good condition. I will send this to our shipping department manager for review.
Great replacement part
I am retired for one year as of now and was involved in trucking for all my working years. I have used etrailer for lights , wiring ,trailer items ect... I now have a class a diesel pusher and have gone all LED inside and out and etrailer has had everything I needed and it all worked without any problems. I will use them for all my trailer and electrical needs in the future.

I installed these lights on our 40 ft motor coach and have put on over 40 thousand miles since install. I drive with the lights on all the time day and nite and they still work with no issues. Thank you
Wow, what a difference LED clearance lights make, especially at night. It makes my business information really stand out and people who follow me really notice that. I've been wanting to go LED the past couple years and now that I recently made the change, I'm not ever going back to standard low-level light bulbs again. Thanks etrailer for offering these lights and at a very affordable price. You were almost half the price as our local part store was selling them for, plus these are more stylish as well.

Perfect. Still shining bright as ever.
Was a perfect replacement for the old burned out lights on my Featherlite stock trailer!!!
Your products are excellent, What I like about it, they're brighter than the standard lights that were on my boat trailer. They were easy to install, they're installed and ready for the road.
Much brighter and way more visible then original equipment. The only way to go!
Thanks eTrailer for the excellent service.
ordered to replace the faded lights on my trailer, fit perfectly. LED will reduce the draw on my light switch.
I bought my Haulmark 12'x6' Enclosed trailer used a few months back. The trailer was in good shape but the sun faded out the marker lamps. Since I use the trailer as a landscape equipment trailer I'm usually not working at night but now with the daylight savings hour change I find myself getting home when it's dark and now those faded lamps were bugging me. Since I've had great experience in the past with etrailer.com I decided to take the plunge and change out the 14 marker lights to their LED versions...Wow what a difference. Not only are my lamps no longer sun faded but they are bright! Definitely was worth the money and the installation was quick since they simply snap into place.
Thanks,
RAM
