Dont spend the money on these. Go on ebay and get your self a set of eurodezigns h4 bulbs. 6000K or 8000K works best on snow. I bought the eurodezigns bulbs for like 10 bucks plus 5 bucks shipping and they work great. There PURE WHITE and, in my opinion, are just as good as the piaa's. I never had a problem and have had them in my sled for over a year! Plus there are lifetime warrenty bulb. good luck!
