Integrating LEDs w/ rear turn signals

Hi everyone,

     I believe this is my first post so I'm going to try to make it simple...

I am currently in the process of practicing relay setups.  For my first project, I want to do the following described application on my motorcycle:

     Two rear turn signals: Left and Right

     Two rear liscense plate LED bolts (there are also two LED washer lenses up front hooked up to a switch in parallel [4 LEDs total to one switch] ).

     I want to try to integrate a relay (or most likely two relays) into this cercuit so that when the LED switch is on and I turn on my turn signals, the two LEDs on either side will flash at the same time the blinkers do.  When the LED switch is off, obviously I want the blinkers to function normally.  I've been reading this forum for a while now and I still have yet to build the proper level of confidence to tackle this project. 

Can you guys/gals give me some ideas as far as what I will need to accomplish this?  Either draw some diagrams or write it out and I will draw the diagrams and you can check my work.  As I said, this is my way of learning how to use relays.  I am planning on starting up a small business for neon and car stereo installations and I know that having relay knowledge under my belt will give me more room to work along with driving in more business.

Thank you in advance.

Matt

edit for last this topic:

The title should actually be Integrating LEDs w/ turn signals (not just the rear turn signals).  My relays will probably be somewhere in the rear so I was just thinking about the rear turn signals...my bad!
