Thank you Bill (our very own national treasure!)

I got radio shack 272-331 - works on test, will finish install after the rain storm stops and the sun comes up.

thanks much to all who responded!

  David,

  Just wire the light directly to the two wires of the fan. When the fan gets 12V so will the light. 

  If you use an LED, which side of the LED you connect to 12V matters. If the LED doesn't light, swap the leads. 

  Common LEDs require an external resistor to operate on 12V. Radio Shack sells LEDs which have a housing and built in resistor so they are easy to mount and can operate directly on 12V.

  Search >>>>>http://www.radioshack.com/ for 276-084.   $1.99        Red LED with Holder Model: 276-084  |  Catalog #: 276-084 

  Have fun,

    Hi kids,

    I need to have a little light to let me know when the cooling fans  
    come on (ford, but not pantera) . . . it seems one could just take 12v  
    off the fan to a light.  It also seems this is a fire waiting to  
    happen - do I need to take the power off the relay???

    Help please . . .

    electronically challenged I remain,

    David in Durango
