Lighting Driver And Controller Ics
Cornering lamps have historically been prohibited underneath worldwide UN Regulations, though provisions have just lately been made to allow them so long as they are only operable when the vehicle is travelling at lower than forty kilometres per hour . “Driving lamp” is a time period deriving from the early days of nighttime driving, when it was relatively uncommon to come across an opposing vehicle. Only on these occasions when opposing drivers handed each other would the low (dipped or “passing”) beam be used. The high beam was therefore known as the “driving beam”, and this terminology continues to be present in worldwide UN Regulations, which do not distinguish between a automobile’s main and auxiliary upper/driving beam lamps. The “driving lamp” time period has been supplanted in US rules by the functionally descriptive term “auxiliary high-beam lamp”.
