Grounded vs. Non-Grounded LED Flasher Relay
 

In swapping over to LED exterior lights, I ran across certain LED flashers that have the ground wire that needs to be grounded in order to function and others that do not have a ground wire. I am wondering what the difference is - why some LED Flashers need to be grounded while others do not?

Thank You!

Mine was like the second one - ground is better than no ground

I couldn't get the old flasher out of the fuse box - maybe it's rusted in there

I was able to change the signal flasher and so far so good...

A flasher with a separate ground connection should flash at the same rate no matter what the electrical load as long as the load is within the operational limits of the flasher.
