Does anyone know how to hookup 4 LED lights with transformor? I'm going to be putting two under the dash and two under the seats in the rear. But was wondering how to hook it up with a switch.

LOL...i just did the same exact thing in my car. I had the local CC install a relay. I put the lights in the car and accidentally blew my ignition fuse...oops!!! But now I've got all lights hooked up and running...I'll post pics as soon as I get a night off!

 

How much did the shop charge for hooking it up?

you do NOT want to use a transformer for leds!!!




The triangle with the line on the end means its a diode. The 2 arrows pointing out mean light emitting diode. The side of the base of the triangle is the + of the diode, the side at the tip of the triangle (with the flat line) is the -.

The /\/\/\ is a resistor. Use 470 Ohm resistors if you want to be safe. You can probably get away with 420 for a 12V source, but a car goes over 14V some times to stay to 470 Ohm, 500 Ohm or something close.


I highly recommend doing one of the bottom 2 scematics as they are the safer ones

usually you can hook 4 leds together in series and only need a tiny resistor like 50 ohm for all 4.

except 2 will be a few feet away from the other 2 in the car

so? use longer wire. you're gonna have to solder anyway

Its better to use more resistors so you aren't trying to make a 1/4 watt resistor dissipate a 1/2 watt and so on. Its safer with more reisistors. Also making the 2 seperate groups undependant of eachother ensures that if one fails it won't automatically make the other fail

I think total costs was <$50...easily...I don't like working on some of the electrical stuff on cars...i always seem to have problems, however, hooking up audio stuff...that I'm ok with!!!

Lets see for this:
4x LED: $5 or less or you are getting ripped off massively!
Resistors: $5 again or you are getting extremly ripped off!
Wire: $10 at most

This shouldn't be any more than $15 - $20 assuming you have a soldering iron, solder, wire strippers, and electrical tape. $20 - $25 if you need a switch

I was refering to having an installer put it in for me.

Oznium sells nice LEDs with the resistors already attached for like 1.29 each. They come with a 12v+ and a Ground lead attached and are both very convient and pretty bright. It's what I used for my HVAC stuff. They are better sanded down though.

$5 for 4 LEDs, are you kidding me? You're not thinking of buying them on RadioShack, are you now?

Btw, what program did you use to do the wiring thing, diskreet?


If you finish this, dear Nytelandz, please post pics of the... mini-install and finished pics. I might be considering this.
