I have a Mitsubishi 3000GT, in the 3Si forum it talks about using LEDs as replacements for certain factory parts. These links give examples of some step by step how tos:

My question is, how would I get a slow pulsation effect on something like this? I plan on doing several of these LED projects and it would be nice to have them all in sync.


Please forgive me, I'm rather novice when it comes to circuits, but I know a lot about computer basics and soldering! I just need step by step and where to buy these things. Thank you all for your help.

 

Define pulsating, simultaneous slowly one and off, or a ripple effect, we've been getting a lot of questions about those lately. Also, how many LEDs are we talking about?
