Help w/ LEDs... *PIC* I got this radio bezel and it lights up w/ blue LEDs. All but two of them are burnt out. I want to replace them w/ red LEDs. Here's a pic of them wired. I know the anode is positive and the cathode is negative and the resistor needs to be soldered to the anode. Now what I don't understand is how you find what resistors you need and how many you need. Any info or a step by step write up would be great. Thanks, Steve.

actually the resistors need to be soldered to the cathode. Use this LED calculator to figure out which resistors youll need. (Mods please dont delete, its only a guide!)

If you wire enough of them (like 3 or 4) in series, then you may not need any resistors at all.
It kinda looks like that what the pic shows, too. I see 4 in series, then another 4 in series. It's hard to tell what's under the heat shrink, but I don't think I see any resistors.

The calculator kraaazymike posted a link to is superb for finding out which resistor to use, and how to wire the LEDs as well.

If you get confused just solder the resistor to the longer wire. There's many of converters to use out there, and I believe he uses 5mm leds, but make sure you find the right size resistor. It's all worth it!

The pink circles are the series. There are 2 sets of 4 LED's each. Chances are there is a small (56) resistor in each series just for safety (dark red circles). The green line is the pos (most likely) and it goes to each resistor. The light blue lines are the neg (most likely) and comes off the end of each series. If you want an exact wiring diagram just shoot me a PM with the LED's you will be using and Ill get you what you need. And remeber when you do the resistor calulator that the car is running at 13.2v's, not 12v.

not trying to hijack the thread...
i've got the same kit in my ss, but when it lights up next to the blue lights on my head unit the light looks almost greenish... have you ever noticed that or did i get screwed?

I didn't get screwed but I've heard of this happening

I had to slow the current coming in... Now it hasn't blown out and it has been in a year.
