Lightweight Antlers and LEDs

I saw a few posts on various horns and antlers but since I had a bit of a twist on mine, I wanted to ask. The antlers on my caribou are going to be wired for LEDs. Thus far the plan is to use flexible led strips throughout, though that may change once we get our hands on them. A sequencer is another option, though I would have to beg a friend for help on that one.

I need a way to make fairly lightweight 'bou antlers that could be wired with LEDs. It's for a toony suit so there doesn't need to be too much realism as long as they look like antlers.

It's not so much the LEDs that are the problem here but lightweight antlers that would work will with them.

Thanks!
