Peterson Manufacturing sells the LED model 907 for the same applications they sell the halogen 507, so I doubt they expect any difficulty in the exchange, nor should I. Both are identical weatherproof rubber housings and the sealed beam units fit in precisely the same way. The only additional modification I intend to add to this is a simple on-off toggle switch, a sealed unit, and a silicone weatherproof 'boot' that screws onto the switch. After all the connections are complete I will seal them against moisture with a small amount of 'Plasti-Dip' which should keep all moisture out of the wiring pretty permenantly. Should work out great.
Please post some pics of this setup once you have it all finished. I'm sure a lot of us would like to see it. I'd also be interested in how it handles under the cold it will get on a snowblower over a period of time.
