Not sure if this is the right thread but need help. I installed led warning lights on the cab of a cat 926m loader and wired them to the factory supplied plug, but now when there flashing you get the flashing noise in the am/fm radio. Any ideas on how to stop this? Thanks
Flashing noise on am/fm radio

Theres RF noise suppressors you can buy (common in CB radio days) you can put on the ground (chassis) of the radio that filters out the noise but also how close to the antenna for the radio is the light close proximity to the LED lights will cause radio noise like a whining or hiss when the lights are running leds in earning lights never actually steady burn they flash at a very high rate of speed thats what makes the noise you can put a noise filter on the negative wire on the leds as well that may help as well
