Cheap & Easy Waterproof LED Trailer Marker & Brake Light Conversion (Under 20 bucks!)


Hey guys, thought I'd photo-evidenciate a quick little project I threw together for the boat trailer.  I had bought some dirt cheap spools of white LED light strips from hung-lo charlie across the pond, and installed them under the kitchen cabinets.  Had an extra spool, and a boat trailer that kept popping taillight bulbs, so i put two and two together and got 5 so I figured I'd take a stab at cobbling some waterproof LED conversions together.

There's a mess of pictures below - first I cut the strips along the cut lines (each strip contains 3 LEDs) and soldered wire leads to each solder pad (pretty simple with a soldering pen, just don't over-do it).  Took about one beer to accomplish.

Then, using a waxed-paper backing, put down a glob of clear marine grade GOOP, pushed each strip into it and covered it with another layer of GOOP (careful to be sure and cover the soldered connections too).  Let 'er set up overnight.  Bam - waterproof LED strips.

Next morning, I just pulled the guts from the side markers and tail lights, and soldered everything together.

For the rear facing tail lights, I did a 3 strip tall single GOOP globular doohickey, the middle strip is the running light and the upper and lower are both flashers.  That way there's lots of light when the blinkers come on in daylight.  Military grade Gorilla tape holds everything into the housing.  Suppose I could have gotten a little more professional but hey Jack, I had the tape.

The photos show most of the process, one photo shows the left tail with LEDs and the right still has the old bulbs for comparison  Should be a one-time-does-it solution, as these LEDs are rated for thousands of hours and it's all waterproofed up.

Just make sure to solder everything, don't waste your time on those crimp connections disbelief.  Surefire recipe for corrosion.  I even soldered the ring terminal grounds on the marker lamps after crimping them.

Enjoy! smile

Very very good stuff and I'll be passing this info along to my boating buds and kids. Lot of Salt Water fishing down here and trailer lights are a regular PITA. Thanks for sharing and good to see you posting, especially good tech stuff like this.

Yankee ingenuity at it's best - although you Canuks might not appreciate the moniker, you are still Norte Americanos after a fashion. I don't have any boating buds anymore, but I sure do like your approach to a pesky problem.

I have come to be somewhat enamored of LED technology, and as they develop better color rendition, the applications in architecture are growing broader.

I used an LED "pancake" light in the shower remodel we just finished (contractor did the work, but I supervised and spec'd it) and it fits the bill perfectly without having to cut a big hole in the ceiling for a recessed fixture can, just a regular four inch cut-in or remodel box. The color is a little "white" for my taste, but it sure does light up that 4' x 5' shower nicely.

These things are slick, and as an old worn out wire twister, I sure wish I had had something like this years ago; and as the technology advances, the will get a better handle on color rendition, and they will be even more appealing.

No problem there Rumbler, my Grandmother - his Great-Grandmother - her family originated in Buch's County Penn. Nice post Bry.
