Headlamps in France

Your assertions about halogen headlamps being unavailable for use in France because of that country's requirement for Selective yellow light were unsupportable because they were wholly incorrect. In fact, a great deal of the development work and initial commercialization of halogen headlamps took place in France. Yellow glass lenses, yellow reflector coatings, and yellow internal filters covering the bulb were among the techniques used to obtain the required yellow light color in conjunction with a colorless halogen bulb. Please refrain from inserting guesses and assumptions into articles, won't you? Thanks. —Scheinwerfermann ^T·_C19:30, 17 May 2012 (UTC)

I had been advised that the reason France dropped the requirement for yellow headlights was precisely because the halogen bulb itself could not be coloured yellow. Whilst I take your point about development work involving yellow internal filters, reflector coatings etc. etc., French law, at the time of yellow headlights specifically required that it was the bulb itself that had to be yellow. A yellow coloured glass front, although it would achieve the same effect, was not actually legal. DieSwartzPunkt (talk) 11:31, 18 May 2012 (UTC)
