LED Buzz

[mitch.wiseman]

Hey guys I have been reading this forum for a while, finally decided to join in.

My question is regarding LED light bars.

I recently installed a Rigid Industries 40" E series on the front of my truck. While testing it my wife noticed the lights had a low hum/buzz while on. I am confident the wiring is correct, and the ground source is directly to the battery. Is this normal?

my guess is the ground...maybe some one else knows and can help you out.

A buzz is typically cause by a poor connection.

I do not know of any reason why a LED would hum/buzz while operational.

I have a 32" bar and 7.5" and haven't noticed a buzz from either
