Bernie give me a break,
I'm to busy typing what was already said
to read what it was !
Dan I don't think this place ever runs out of opinions
though a lot of times we forget the question
LED concept was to be brighter at reduced electrical loads.
Now that the entered the toy catagory instead of just straight replacements,
the load of an LED setup could exceed the factory supply.
To be sure you should do the math yourself
(sometimes that's just reading the package).
One misconception some folks get fed to them is that
by replacing with a LED fixture the power draw (wattage)
will be less. Not if the manufacturer is trying to avoid complaints
about the flashers going to fast or car telling you bulb is burnt out.
So what they do is basically add a resistor across the LEDs to draw
more current so the flasher thinks all is good. It is all good, but
you have not cut the load one bit. Read them or measure them.
Trailer lights are on seperate fuses for many new trucks
and the fuses are somewhat more forgiving because they are not
supplying the trailer with truck so it's an "unknown".
Figure your total loads and don't get to close to fuse rating.
Dang it, Bernie, you're still typing too fast for me, I see you got to
some of this already. I don't care, I'm still posting it.
