"I still opted for LED trailer
"I still opted for LED trailer lights (and will use the led replacement bulbs to change out the 1156/1157 automotive lights that are currently in my nav lights on the boats as well since the price has dropped at a local retailer to below 10 bucks a bulb).
I understand JWB's concern but I kinda look at it the other way.
Since it seems that most "bulbs" barely last a season on the trailer in some cases (can't count how many times I've been fiddling with the wiring/bulbs in the driveway or boat launch trying to get one side to light up) and the LED's are often advertised to last 10,000 hours (2 or 3 times the life of my trailer I'm sure), I have simply added inline fuses to the harness (the assemblies cost less than a buck at most auto supply places - even got a little waterproof (box) that mounts on the tongue to contain all the connections for a few extra dollars).
Now I don't worry about having NO trailer lights, which used to be a constant issue (however, to be fair both my boat trailers have only been fitted with LED's for the past two seasons, but holding up perfectly so far).
In fact, in Ontario where I am, all commerical vehicles above a certain weight, including their trailers and all vehicles transporting compressed gas products MUST have LED's for brake, signal and running lights (too many burned out convential bulbs which posed a safety issue).
At least here, it's probably just a matter of time before it's law on all new vehicles/trailers which is why I kitted my trailer(s) with them."
