Sidgreaves - MD}16/E29.1.34 For parking purposes our side lamps use too much current. It has been possible for many years to use what I think is called a 'rheostat' to reduce the amount of light given by a lamp on an ordinary house circuit and reduce the current consumed. I remember I had one in a house 10 years ago. Is it not possible to introduce something quite simple like that on our cars for parking purposes? As long as there is sufficient glimmer of light to comply with the law, that is all that you need. Sg.{Arthur F. Sidgreaves - MD} | ||
