Title: LED lights.
Post by: muddyjames on October 10, 2007, 20:58:08: In the disco I have 1 LED light under the radio that flashes when the alarm is on.

How easy is it to wire a few more into parallel as I want to light up my devil duck when the alarm is on and put a few LED's up inside him. I think it would look quiet groovy.

Also would a few LED's be ok inside a devil duck or wont the duck like it up em (said Mr manering!!)

Post by: muddyjames on October 10, 2007, 22:02:28: but at Â£5 looks like a good price.

Mainly though are they the type I need to look for or are there different size led's?

which size do i need if so?

Post by: muddyjames on October 10, 2007, 22:32:44: I think i will need at least 6 led's inside the duck. I am just worried about how many bulbs i can run off the original led light there.

Post by: kizz81 on October 10, 2007, 22:35:19: check on the maplin website sorry i dont know the URL

your radio LED is most probly 3 mm i would use the new style bright 5 mm leds for what your looking to do, i used 5 mm super bright blue led on a custom tily meter and i had to put a huge resistor on it simply because it blinded me evan in the brightest of daylight,

yh i would suggest your local maplins store or the main website they have most stuff in stock to do with electronics

hope thats of help to you
cheer kieran :D

Post by: muddyjames on October 10, 2007, 22:39:09: I am a very very very amature person when it comes to electrics. If I run a 5mm wire in I would need to go back to where in the circuit? I am guessing that would be a whole of dash board out job? I dont fancy that tbh!!!

and as for resisitors. that flew over my head big time!!! :lol:

Post by: kizz81 on October 10, 2007, 22:44:51: lol im no expert i think all of my electrics have burnt out in the landy now :lol:
what i would do is run a wire from the radio feed and hope for the best :lol: you shouldnt need to bother with resistors you wont be pointing them towards your self, i would get a couple of 3mm red leds to give the duck a nice glow

perhaps better find some one who knows how to wire stuff up

cheers kieran

Post by: Guyh2 on October 10, 2007, 23:44:56: You can get 12v flashing LEDs so no need for current limiting resistors etc.

Easiest way to wire them up so they flash when the engines off is to wire the anode(long leg of the LED) to a permanent 12v (via a fuse) and the cathode (short leg) to an ignition switched 12v (should also be via a fuse), then every time you switch the ignition off they will flash.

Stick to 5mm LEDs 10mm LEDs are BIG !!

you only need thin wires just make sure the wire has a current rating above the fuse rating.

Post by: Evilgoat on October 11, 2007, 10:24:39: Be careful, theres a lot of conflicting advice about.

A standard 3/5/10/25mm (yes they make em that big!) Will need a dropper resistor and wont flash. Fail to fit the resistor and it will incinerate. 330r should do it for most LEDs

12V LEDs are available as are 12V flashing ones. These need to be wired so theya re only on when the ignition is off. This is do-able with a relay or if you have an alarm with an 'armed' line its a doddle.

If you know someone that is good with electronics then do a search on google for electronic snake eyes. I have a circuit like this built to go in one of the ducks at some point. Instead of flashing it glows earilly :)

Finally, the one you already have may just be a normal LED, most alarms use them rather than flashing ones. You'll find that it will probobly also have a resistor in the alarm (but it could be a 12V LED too) so I'm not sure tapping it is a good idea.

Get a relay with NO and NC contacts (5 pin VS 4)
Wire the coil in so it comes on with the accesory circuit. The wire your LED to power accross the common and NC terminals. When the coil is powered up the power to the LED is interrupted, the revers of the normal wiring. When the power is removed the contacts close and the LED comes on.

Post by: Boddle on October 11, 2007, 12:00:39: You may fined using an LED system that fits into a standard fitting (Like side lights or side repeator, ETC) maybe the simplest way and are design for 12volts.

Is where I bought most of my LED from in the past
There are some out there for motorbikes which the on LED rotate round the side light bulb it would make it look more like its on fire. You'll have to do a search on Google (or who ever you wish to use) for motorbike LED
