Installed OPT-7 Led conversion kit to replace factory. I now have radio interference when lights are on. Radio works fine when lights are off. Have anyone else dealt with such issue & if so, how did you fix it? If I can't get it fixed, I'll return them.

 

Yes it is normal. You will need chokes that clip on to the wiring leading to your lights. Chokes help cut down on the electrical frequency. You may need to use more than 1 on each light. You can get them on E bay for about $11. They are advertised for computer wiring.
