Why should I upgrade my trailer lights to LED and submersible units?

LED submersible lights are brighter, more reliable, and resistant to water intrusion. They last much longer than traditional bulbs and significantly reduce electrical issues caused by frequent boat launching.

What problems are caused by old or damaged trailer wiring?

Worn wiring can cause flickering lights, brake light failures, blown fuses, or complete loss of lighting. Corrosion from saltwater is a common issue, which is why rewiring is often the best long-term solution.

What is included in LED trailer light rewiring service?

The service includes removing old wiring, installing marine-grade sealed wiring, upgrading to LED submersible lights, securing proper grounds, and fully testing brake, turn, and running lights.

Are LED trailer lights legal and DOT-compliant?

Yes. We install LED lights marked DOT, which means the maker certifies they meet the federal lighting standard (FMVSS 108), and wire them so the tail, brake, turn, side-marker and license plate lights all work. Trailers 80 inches or wider also need clearance and identification lights; we check what your trailer needs for its size and tell you if anything is missing.

Can submersible LED lights prevent future corrosion issues?

They help. The sealed LED units keep water away from the electronics, and with sealed heat-shrink connections and a dedicated ground wire, corrosion and repeated light failures become much less common. Rinsing the trailer with fresh water after each launch still helps.

How long does LED trailer light rewiring usually take?

Most trailer rewiring and LED upgrades take 1-2 hours, depending on trailer size and wiring condition. We test every light before the trailer goes back on the road.

Does upgrading trailer lights improve towing safety?

Yes. Brighter, more reliable lights make your trailer easier for other drivers to see, especially at night and in poor weather, and working lights are required by law.

About this service

Visibility & Safety

Lights Built
for the Ramp.

Traditional boat trailer lights fail because they aren't designed for submersion. We install completely sealed, waterproof LED trailer lights that are brighter, safer, and designed not to blow out.

The Incandescent Failure

Hot glass bulbs shatter when hit by cold seawater. Sockets corrode, and grounds fail. Old-school trailer lights are a constant game of "fix-it" before every trip.

Submersible Tech

Our LED units are IP68 rated for submersion, and the circuit board is potted in resin, so water cannot reach the electronics. These submersible trailer lights are designed to go underwater at every launch.

Complete Rewire

In boat trailer repair, changing the light unit isn't enough if the wire is rotten. We pull the old boat trailer wiring harness out of the frame and fish new, marine-grade tinned copper wiring from the tongue to the taillights.

Installation Standard.

We don't use electrical tape. Ever.

Strip & Fish

We remove all old wiring and clips. We fish a new harness through the trailer frame to protect it from road debris and sun.

Dedicated Ground

The most common cause of flickering is relying on the trailer ball for ground. We run a dedicated white ground wire to every single light.

Heat Shrink

All connections are made with adhesive-lined heat shrink butt connectors that melt and seal the wire against saltwater intrusion.

Verify

We test running lights, brake lights, and turn signals using a dedicated 12V supply to confirm everything works before you arrive.

Bright & Waterproof.

Be seen on the highway, day or night.

Common Questions

Why do my lights flicker?

Flickering is almost always a "Bad Ground." Most trailers use the metal frame as the ground wire. Rust breaks this connection. We solve this by running a physical ground wire to each light.

Are LEDs really waterproof?

Yes. Unlike old lights that relied on a gasket (jar lid) seal, modern marine LEDs are "potted," meaning the electronics are encased in solid resin. There is no air inside to leak.
