Compatibility of Cyclops ultra 10.0 led headlamp with Commando

I’m interested in switching from stock Lucas headlamp for Cyclops ultra led. I’m concerned with it not being compatible because of positive ground. I’ve read some older posts before the Cyclops Ultra came out that seemed to indicate the older models would work so I’m hoping I can make the Ultra work. I appreciate any help with this. I know there’s a huge knowledge base here.
