1.1 INTRODUCTION: In an automobile headlight‚ a ’meeting’ beam (dip beam) is provided in addition to the driving beam (high beam) so as to reduce the dazzle for those approaching head-on to the vehicle. The Auto Dipping Device for a head light is intended to automatically change the Headlight Circuit to either driving beam or dip beam given a particular set of road conditions‚ without the intervention of the driver. The present practice is to operate the dip switch manually. The function

Spring 2004. Choice-based conjoint analysis (also known as Discrete Choice) has been applied to reveal the relative importance of various product attributes for consumers. The EU Energy label is used for the two product categories in our survey‚ light bulbs and washing machines‚ and we investigate the relative importance of this eco-label compared to other product features (like brand name) in consumers’ purchasing decisions. We discuss differences between the two product categories‚ and draw conclusions

with fluorescent bulbs. The cost of these bulbs has come down to the point where they are now very cost effective and they consume much less energy. They screw into your light fixtures like a traditional bulb and last up to 13 times as long. The bulbs you can buy today are much higher quality than in the past with less flicker and with a warmer light. Because an incandescent bulb wastes as much as 90% of its energy as heat‚ the power consumption of the cooler-running fluorescent bulbs is much less.
