When I talk on my cb radio my rear led cubes turn on everytime my voice goes over the cb, anyway to make this stop?

 

are the lights grounded in the back or at the battery?
are the lights tied together and is the cabling running next to the CB antenna cable, if so separate the two. Antenna cable should be run by itself. Also the splice where the lights are tied together may need to be shielded more.

 

Where is your antenna mounted?

Do you have a 'tuned' radio (high power)?
