Wellmax LED Boat Trailer Lights
Best for: Boat owners replacing a pair of low-profile tail lights with a submersible design. The kit includes two 12-volt LED lights for tail and turn signals, plus stainless steel fastening hardware.
The listed features describe completely sealed lights with acrylic lenses and corrosion-resistant materials. The product is stated to comply with DOT FMVSS 108 standards. This is a practical choice when water exposure and a straightforward two-light replacement are priorities.
Limitation: The supplied feature details identify tail and turn signals but do not list license-plate illumination or clearance lights. Confirm the functions and wiring you need before ordering.
CZC AUTO Submersible Rectangular Lights
Best for: Buyers who want stop, running, turn-signal, and license-plate illumination in a pair of rectangular lights. The manufacturer lists the lights for marine trailers and trailers both under and over 80 inches wide.
The product uses LED diodes and is rated IP68 in the supplied details. Sonic-welded sealing, additional sealed edges, and 18-gauge copper wires are listed as design features. Choose this option if a broad set of rear-light functions matters more than a minimal replacement light.
Limitation: The supplied information describes the lights but does not list a wiring harness or mounting hardware as included. Check what is needed for your installation.
Partsam Square LED Trailer Lights
Best for: Owners who want more than brake and tail illumination, including side markers and reflectors. The listing describes a pair with different left- and right-side functions: one light includes a license-plate illuminator, while the other provides the listed rear and side lighting functions.
The lights are described as submersible, IP68, and DOT compliant. The product is listed for trailers under 80 inches as well as several other vehicle types. Choose this set when side visibility and built-in reflectors are useful additions to the rear lighting.
Limitation: The listed application specifies trailers under 80 inches. Verify trailer width and which light belongs on each side before installation.
LINKITOM Submersible LED Trailer Light Kit
Best for: Buyers looking for a broader kit rather than two replacement brake lights alone. It includes two stop-and-turn LED tail lights, two amber clearance lights, a 22-foot and a 4-foot wiring harness, a license-plate bracket, and reflective stickers.
The listing describes welded, sealed lights with an IP68 waterproof rating and corrosion-resistant ABS lamp shades. It also specifies that the lights should be installed with their drain holes facing down. This kit is a better fit when the trailer needs additional clearance lighting and supplied wiring.
Limitation: Correct orientation matters: the manufacturer says to point the drain holes downward. Check the included harness lengths against the trailer layout.
Partsam Low-Profile Rectangular Light Kit
Best for: Owners of trailers over 80 inches wide seeking a multi-function rectangular set. Listed functions include stop, tail, turn, side marker, side and rear reflectors, rear clearance, and a driver-side license-plate light.
The product description identifies welded sealing, DOT compliance, and zinc-plated hardware. It also provides dimensions of 8.42 inches long, 3.27 inches high, and 2.87 inches wide per light. Choose this set when the listed wide-trailer functions and specified size suit the mounting area.
Limitation: The stated application is for trailers over 80 inches wide. Measure the available mounting space and verify the intended left/right placement before buying.
Buying Guide: How To Choose Boat Trailer Brake Lights
Do the lights need to be submersible?
If the trailer lights may enter water during boat launching, compare products explicitly described as submersible or sealed. The listings here include IP68 ratings for several options, while Wellmax describes completely sealed lights. Follow any installation instructions, such as LINKITOM’s direction to mount the drain holes downward.
Which light functions should you compare?
At minimum, confirm that the set provides the stop or brake signal, tail light, and turn signal functions your trailer needs. If useful for your setup, look for license-plate illumination, side markers, reflectors, or clearance lights. A kit with extra functions may require different wiring or mounting arrangements than a basic pair.
Does trailer width affect your choice?
Check the product’s stated application against your trailer. Some listings specify trailers under 80 inches wide, while the Partsam low-profile kit is described for trailers over 80 inches wide. Width is also relevant to the complete lighting arrangement, so confirm local requirements rather than assuming every pair covers every trailer configuration.
What should you check before installation?
Compare the light dimensions with the mounting area, identify left- and right-side units, and review the listed wire or harness details. If a kit does not state that wiring or hardware is included, do not assume it comes in the box. Verify the trailer’s existing wiring and required functions before removing the original lights.
Frequently Asked Questions
Can submersible trailer lights be used on a boat trailer?
Yes. The products described as submersible are intended to handle water exposure, making them candidates for boat-trailer use. Check the specific product’s sealing details and installation instructions.
Do LED boat trailer lights include brake lights?
Several products in this list explicitly describe stop or brake functions. Check the individual feature list because not every light description specifies the same combination of functions.
Are all boat trailer lights compatible with every trailer?
No. Trailer width, mounting space, wiring, and required light functions can differ. Compare those details with the product specifications before purchase.
Why do some trailer light kits include amber lights?
Amber clearance lights provide additional lighting for a trailer setup. LINKITOM lists two amber clearance lights in its kit; check your trailer’s needs and applicable requirements to determine whether they are appropriate.
