Trailer light requirements?

I need to replace all the lights and wiring on my trailer. It's got the two main stop/turn signals, and then 3 running lights on the back and one near each fender. Are these running lights legally required? 99% of the time I don't tow my boat in the dark, and I'd rather just leave these lights off. Can I get away with just having stop/turn signals?

Re: Trailer light requirements?

I didn't have running lights on my old boat trailer, ZmOz. I do have the same set-up on my trailer now (3 red running lights on the center rear & yellow marker lights at the fenders), and since I run with my lights on even in daylight, I think they help make me more visible. However, I believe they're 'cosmetic' and aren't required, but you should probably check with your DMV to be sure.

Re: Trailer light requirements?

The 3 red lites at center rear of your trailer are required for trailers over 80 inches wide. The trailer manufacturer wouldn't have spent the extra to put 'em on unless he had to, so your trailer is prob'ly over 80" wide and you need to keep those lites.

Ditto what pacific coast honda said. The 3 red in center of back are wide vehicle identification lights, just like on a semi or a dually pickup. I believe the fender/clearance/side marker lights are also required on over 80" wide trailers. I think you can get by with reflectors on under 80" wide, but not sure.

If you go to Yahoo type in Federal trailer lighting requirements, it will tell you what you need for your trailer and it shows pictures where they are to be placed. If you can get there by the address, I couldn't. It is http://jeepgod.net/trailers.html

Re: Trailer light requirements?

ZmOz - It looks like the trailer light manufacturers use different definitions of stuff than us common boat folks. "Submersible" to them means the kind of light that traps a pocket of air at the top in the hope that the air will keep the bulb and receptacle dry :rolleyes: . That's why you don't see anything to physically keep the bulbs dry. They call the kind of light where the bulbs and their receptacles are actually totally sealed in an inner capsule "waterproof". Here's an example:<br /><br />Waterproof Lights<br /><br />I have those and used to always think they were "submersible" but now realize they're called "waterproof". I've been dunking them in the ocean for over 5 years and they've held up without problems very well :) . A trailer I used to have had the air pocket "submersible" ones and they corroded out right away :( . Remounted them to the transom, but then had to take 'em off the boat before every launch. Much simpler to just leave the "waterproof" ones on the trailer :D . Others here like LED lights, but I've no first-hand knowledge of them so I'll defer to those others to tell you about the LED lights. When you're ready to switch, go with the "waterproof" or maybe the LEDs. Good luck.

Re: Trailer light requirements?

Hmmmm....here's the thing...<br /><br />I'm rewiring because somehow last year, all the lights decided to stop working at the same time. It's quite weird, it appears that the two main lights died from corrosion, at the exact same time. I had to drive about 100 miles without lights, to where I killed my motor. Wow...that was a fun trip. :rolleyes: <br /><br />Now, I'm trying to fix my current lights, rather then replace them for 3 reasons. 1)I'm cheap :D 2)Someone bet me that I could never make "that old crap" work again. 3)I'm getting rid of this god forsaken pile of crap in the spring.<br /><br />Back to my question....to "fix" the lights I think I'm going to solder wires directly to the bulbs. I'm not worried about corrosion, but I am worried about dunking the lights and blowing fuses in my truck. Do you think this will be a problem?

Re: Trailer light requirements?

What will you do if you lose a bulb before you sell it?<br /><br />If a hot wire comes loose and touches bare metal (ground) it probably will harm your truck wiring, depending on the interface between the truck and the trailer. (i.e. using and electronic adapter.)<br /><br />Doing the lights like that may make it harder to sell. (Unless you plan to keep it a secret, and that would bring up a moral issue.

BTW - I replace my trailer lights with Sea Sense LED taillights. They are wonderfull and trouble-free.

Solder in a new one. :) Shouldn't be a problem though, I just bought two new "long life" bulbs. I don't think needing new lights is much of a deterent to a buyer, when I bought it to begin with somehow the previous owner managed to smash 8 of 9 reflectors/lenses... :rolleyes:

Dunking the lights and blowing fuses in your truck won't be a problem if you disconnect the trailer connector from the truck as part of prepping the boat before launching.<br /><br />

If "...all the lights decided to stop working at the same time" there's likely a common cause, like the ground connection to the trailer went bad. Check that the white wire from the connector is making good contact with the trailer frame. Maybe you can avoid trying to do all that rewiring and soldering, which IMHO would be difficult to do well and leave you with a decidedly subpar installation.<br /><br />It'd be tough to make a good solder connection 'cause the wires are prob'ly corroded and you'd have to clean the strands before solder would flow on them. Then to avoid a cold solder joint you'd have to heat the bulb connections to the point where you'd run the risk of the internal bulb connections coming loose. And for the double filament bulbs, you'd have to ensure the brake/turn and running light wires didn't short to each other where they'd be soldered in close proximity on the bottom of the bulbs. And even if you got all that done OK, then you'd be left with the bulbs hanging by the soldered on wires and the resultant bouncing around every time the trailer hit a bump will shorten the life of even the 'long-life' bulbs. JMHO, it's your trailer, you get to make the final call.

Re: Trailer light requirements?

I would have a lot of pity for someone who bought that trailer, if some quick shoddy work was done to make the lights work. They buyer will pay for it all in the long run.<br /><br />It sure does make an arguement for not buying used.......

You'd think...but I cut the wires for both tail lights and connected them both directly to a battery. Neither work.<br /><br />

I'm using new wire all around, and I've soldered to this kind of bulb before for other projects. Works great.

I love how you just assume I'm going to do a crappy job and then lie to a buyer about it. :rolleyes: First of all, the trailer is quite obviously an old peice of s**t. Any buyer knows what they're getting into. Secondly, the boat and trailer will be in 10 times better condition than when I bought it, and I plan on selling it for the same price...

Re: Trailer light requirements?

Sorry if you are offended, but my opinion is that having wires soldered directly to the bulbs shoddy.<br /><br />And I did say "Unless you plan to keep it a secret". So I wasn't assuming you would lie.
