LED Marker light grounding.

[briheath]

I would like to install LED marker lights on my 65 tradewind. The original lights are grounded to the body through the rivets. Can I use the second/extra wire on the LED lights to make a universal ground for all the lights? I would connect the power to the light then connect the ground to a ground wire run it to the next one and so on until they all terminate to a designated area. he tail lights are wired this was because of the plastic housing they are installed into. I have the interior gutted so doing this won't be a probelm. Is there anything that I'm missing? Is it worht the extra effort or should I just ground them to the body like the original lights?

Thanks
Brian
