My trailer's electrical box design

Forgive the intrusion but have you Americans given up using the word well ?

Graham

Iggy is not exactly an American, he is an import! Greg

English is not my native language, so do not consider me a standard of American English!

"He's fallen down the well. Well, well, well."

I didn't realise. Curiously though you do seem to have adopted a habit I've seen from other US posters of using adjectives as adverbs.

Graham

I thought you shot a video of something.

You have inspired me to make a video of my Dream PC 2006...

I have done it before though... quality of video is low but still fun.

Bye, Skybuck.

Deep subject. Dark too.

I'm an American and I cringed at that, too, Graham. (And we 'Murricans usually put quotation marks around the word in question, "well" in that sentence; don't you?)

That reminds me of the joke my dad told me one evening when we stood on the banks of Lake Ouchita in Hot Springs, AR on vacation. I was 10 or so years old:

Two guys were standing next to a stream peeing and one bragged "Ooh, the water's cold today." The other bragged "Yeah, deep, too!"

For those of you in Rio Linda (and West Palm Beach), I'll explain it to you if you like. Jes' holler, y'hear?

Hi Graham

Forgive the intrusion, but, who are "Americans"?

Jerry

Eeyore is a lame British troll, so just ignore him. He lives only to damn anything American. He pollutes the sci.electronics.* newsgroups with his hatred and ignorance.

I think that I received some meaningful comments from him in the past. Anyways, this thread has veered a little away from where I wanted it to go, specifically I would like to hear if these LEDs are a sensible idea or not. I left them powered with 15V overnight, so far they have not burned out, so perhaps 500 ohm resistors are acceptable. I will keep them on until tonight. The series resistors are hot, but still they can be touched without getting my fingers burned.

Do you really need them to run at ~ 25 mA ? I assume these are standard 30 mA @ 25C LEDs. In my view, it would be better to run them a lot lower. I'm thinking of times when the sun is beating down and it is really hot. Running them at a lower current might be beneficial.

Ed

over here it's illegal to have forwards-facing red lights (maybe go with blue, or amber instead?)

by reading the manufacturers data sheet you can tell what current is acceptable by the led.

for a 12V system if you want more brightness put more LEDs in series,

painting the back of the led and the front of panel it's fitted to black helps with visibility.

I ran an ordinary 20ma red LED off a 5v supply once, with no series resistor, just to see what would happen. It passed about 100ma and lasted more than an hour.

I doubt they will burn out in the amount of time I tow the trailer. They need to be visible in my rearview mirror. I did measure the current, it is indeed 25 mA, as you stated.

This is for brakes, not for brake lights. My trailer's axle has electric brakes.
