I've had Alpha's on my last 2 Ski Doo's. Outstanding quality kits. Just plug and play. It's a 5-minute install on a Gen 4 REV. The difference from stock is literally night and day. Just as bright on my Gen 4 XRS as on my buddy's gen 5 XRS with the factory LED's. I'd even go as far as to say they outperform the Gen 5 LED's. Don't be fooled by the cheap LED's sold on Amazon. Those are nowhere near the major league light these bulbs produce. These are worth every penny if you ride at night.
Installed h13 kit in my gen 4 ski doo renengade. The difference is black and white. 2-3xs as bright as stock gen 5. Can't speak on longterm as have only had them 2 weeks but as of now nothing but impressed.
This product is superior to all others on the market. Over the years I put them in all my sleds. Mr Sean it's always a pleasure to talk to. If you're in the market for these lights do yourself a favor, go straight to SII. I you will not regret it!
Best investment ever, I have these on three of my snowmobiles now they are the best snowmobile headlights i’ve ever tried, quick shipping from Canada to the lower 48, very pleased with this purchase
Tried cheap leds before I went to sii and there is no comparison at all the beam strength and field of view is amazing!
