L.E.D.s how??

[quickstopdante 10+ year member]

so ive seen various posts about LEDs in vents and door handles and all that stuff. I'm just curious how you wire it ? like can you just tie ten of them to a switch and drop it straight to the battery or what? i'm curious for step by step details please.

I'd use a relay to provide the power and a switch to activate the relay. LED's use very little current, so it should be no problem to put several on a single circuit (fused of course) Also remember led's are one way only, if it's wired backwards, they won't light up. I think a 7.5amp fuse would be enough for a circuit containing 20-30 small leds or so, though you could determine load when you buy your led's, I am reasonably sure it will say how much current they use, and I'd run them in a series-parallel circuit.

say i wanna put like 10 in. how exactly would they be wired. i know its a lot to ask for but i'm askin for diagrams and stuff. i mean i don't wanna screw this up.

I'll see if I can draw it out for you in the morning and send it via email, or pm or something for you. I have never done it personally, but I know a hell of a lot about automotive electrical systems (ASE Master Auto technician). Where are you planning on putting them? How many branches (1 branch for each door? a branch under the dash?) Are you buying led's from radio shack to string together or are they pre wired and you hook them up?Let me know.

i havent made any purchases yet. i'm thinking one in each of the 4 front vents, maybe some other places. i drive a 4 door sedan.

what ever you do you need the final voltage to equal 12volts. you cannot wire them below that or *poof* they all go away. wiring in series (positive to negative) is the easiest way to achieve the 12 volt requirment. divide twelve by the number of LED's you want to add and then take that number and buy LED's that have that number as their voltage.

( LEDs typically come in 1, 2, and 5volt. )

and all the number in between. Radio shack has butt loads of differing voltages.

I was gonna save the images and post it in a thread, but my computer is funky and will save everything as a bitmap image instead of the original format.

Those diagrams are perfect, The only thing I would change is to use a relay, though it adds a little complexity.

my question with LEDs, how do you determine the resistor values?
