Generally old cars don’t have great electrics, luckily Vincenso Lancia used Bosch so at least electricity is the end product rather than smoke produced by that well known English brand. The Bosch generator like most of the Vintage era put out about 80 Watts, so that is my power budget. Unfortunately the Lambda is handicapped with a dud vac tank so has a Facet fuel pump sucking 18 Watts.
Here is the list of stuff that would be running while travelling at night.
|LED Tail Lamps||2||2W||4W|
So I’m 12 Watts over budget if the Generator was perfect, this is after I had already replaced the headlight bulbs with halogen ones saving 10 Watts and Stuart the previous owner replacing the tail lights with LEDs saving another 12 Watts. The obvious answer would be to get the vac tank working…. or LED Headlamps?
Some new cars now come with LED headlamps so they would be perfect for an old car with not much power to spare…. Well yes and no. Here is a picture of one I prepared earlier.
Picture shows LED mounted in part of the Bosch reflector, would have been a perfect fit if that heat sink was not sticking out the back.
So the problems are
- No room for the fan/heat sink.
- Nowhere for the heat to go as headlight shells are not ventilated.
LEDs although much more efficient that incandescent bulbs still produce heat and if the heat cannot get away they die early.
I think the real problem here that I do not have a vintage brain, as I’m sure in the day if your battery was going slowly flat it was time to pull over and have a kip and take off again in daylight, problem solved.
Nevertheless, a vac tank may allow me to see the light without the sleep.
