As far as I can tell Munson was the first .These are his kits.Now I make them.I even supply the original instruction.Thanks to a happy customer.The buckets fit a little better .The lenses are a little more scratch resistant.And the bulbs can have a higher wattage.All the style is still there.Being chassis mounted means a more stable beam.For $450+$50s&h you could even have blue lights if you wish.R.T.
